Excellent article. You haven't missed anything that I can see, and hit all the right emphases. Perhaps in the discussion about "application of new techniques to recovery from old oil fields", it would have been worthwhile to mention EREI, or better OROI (as I note you did reference tar sands). Tar sands are an unusual case though, because though perhaps true that the energy return may be less than the energy invested, it is easily forseeable how to get the required energy from very low-value waste coke and un-processed tar (in-ground Toe-To-Heel heating, coke gassification to produce hydergen et.), so there is still a significant Oil Return on Energy Invested. Conventional oil fields and particularly offshore ones present a different case, as most of their energy inputs come from high-grade oil and refined products. There can be no discussion of their further development or operation once their Oil Return on Oil Invested goes negative.

Fred, It must be gratifying to publish this article today as oil has just reached $133 as I write these words. With each passing week you can say to all the disbelievers you have written about 'I told you so all along'. Superb article in not only its eloquent command of the English language in writing, but also in its sobering message to the western economies that import oil. Knowing the ingenuity of western engineering historically, and knowing how design engineering has advanced tremendously with the help of computers in all fields of engineering over the last 20 years or so, there is an element of truth to that gentlemen's paper in Petromin. At the oil price levels we are headed for, western private enterprise is already salivating at developing and perfecting and commercializing alternatives to oil, particularly for transport energy needs as Len has said. The prospect of making lots of money in an energy hungry world is steadily becoming a powerful motivator to innovation in step with rising oil prices. I sincerely hope some enterprises become wildly successful before it is too late and (more) wars are started over oil. A related example of this motivation is happening here in Ontario Canada. Our provincial electricity industry regulator the Ontario Power Authority has signed up so many wind and solar energy applicants to build these alternatives in Ontario, it has amounted to something like 10 times the amount they expected to sign up over a number years, all on board in just one year ! Keep up the great words on this website Fred, it needs more people like you to be vocal on it.

Another gold star article Fred. You'll like this article, just published today in the Wall Street Journal I'm sure. I'd also recommend watching the video on that page. Bob is right however, in stating that the high price is indeed a GOOD thing, and is bound to bring out replacements or behavior modification. Hopefully one of those happens before the Cassandra-like predictions of doom and gloom manifest themselves. As always the item in shortest supply worldwide is actual intelligent thought, versus what we are treated to on a daily basis by our so-called 'leaders'.

"I told you so all along". Music to my ears, but I'm afraid that what we need now is not music is a way out of this mess. Agreed, technology and the right kind of leadership can do the job, and in fact will do the job - but will it do it soon enough. What we also need is for someone to go into these great comments on EnergyPulse - especially the ones about alternative energies - and formulate a coherent/comprehensive description of a coherent energy policy. I must say though that in the middle of my song-and-dance in Paris I suddenly had a bad feeling about what is around the corner oil-wise. . In my lecture I think that I made one mistake - I put in a good word for nuclear. That put a frown on a few faces. Funny, but even in a country where nuclear supplies eighty percent of the electricity, there are some high achievers who think that wind and wave will keep them supplied with Armani gear. Fred

Here's a little ditty for your musical tastes there Fred. I know you're not keeping up on things here stateside, but after all, when the US sneezes the rest of the world catches a cold. When I spoke of leaders, I couldn't have asked for a better second verse than this one: INCONVENIENT TRUTHS ABOUT OIL Nothing funnier than politicians out to excoriate oilmen getting eviscerated instead. Naturally, the usual media suspects couldn't be bothered to report on this.

Ferdinand E. Banks 5.26.08 |
Thanks Jeff Jeff, I really liked that piece until its author mentioned the wonders of shale. That's when Fred tuned out. Most of the oil that he is talking about aint there. Trust Big Oil and Big Business on this. As somebody pointed out in this forum, what is needed is a comprehensive/coherent energy plan based on the scarcity of oil (and perhaps also gas). I can't think of any persons in the world better suited to the framing of this program than the regular contributors to EnergyPulse - by whom I mean first and foremost the individuals contributing comments. Some people dont have much to offer here, where by "some people" I am primarily thinking of yours truly (i.e. my good self), but if those commentators could put their knowledge into articles that might be just what the energy doctor ordered. But, regardless, we must all try to pull our weight in this. Even ol'' Fred has decided to try and get over his basic distaste for environmentalists and do his part, as long as doing his part doesn't mean having to rub elbows with politically correct academics and similar hypocrites.

Enjoyed the article very much, and I'm going to buy your book; my curiosity demands it. I have seen one plan for an alternative which was very technically practical, realistic, and achievable documented in ISBN 978-0-595-43519-7. As an aside, if you read it, my view on the financial side, is that it could cost about the same as the estimate for ethanol. It was been presented by populist to several governors in the US today, and many commentors like the one who confronted you in the past have been outed in the process. They really to need to hire qualified people instead of actors. Anyway, there is another saying in the 'American' Navy too, "One ship, one screw"; and many people aren't intended to get the message as well, too risky.
|

Ferdinand E. Banks 5.27.08 |
Thanks Bill, and now that we are trading sayings from the US Navy, I will give you another: 'Every ship can serve as a mine-sweeper...once'. Anyway, I received a letter from a gentleman telling me that I didn't know mine from a hole in the ground because I said that the energy input into tar sand oil might be greater than the energy obtained. I think that this is very likely, though I am not certain, however since he only took into consideration the energy in the gas that is used to obtain that oil, I had to inform him that maybe he didn't know what he was talking about. But let me say that I am NOT against the exploitation of tar sand oil, nor am I losing any sleep over the possible energy deficit involved in obtaining that oil. The more oil from any source the better, but the point is that it is not going to be enough for reasons that I suggest in my paper.

Bill Corbin 5.27.08 |
Your welcome Fred, and I'm in complete agreement. Here in old USSA, I'm watching the political response, and it wasn't gotten to the point where they're running "UFO" stories, so sad. Anyway, I tend to think, if it doesn't work in the 4 years, then 'they' need to pray for Fado music and carnations.

Fred, You indicated that high oil prices could provide an opportunity for technological development. One person pursuing technological solutions is Vinod Khosla. He was a co-founder of Sun Microsystems and was also involved in several other dot-com companies. He is providing venture capital for about 35 companies, mmany of which deal with alternative energy supply or demand. Keeping with the Inconvenient Truth theme, his recent presentation is titled "mostly convenient truths from a technology optimist." It is located at: http://www.khoslaventures.com/presentations/WIREC3052008FINAL.ppt#1 Chris

Another Gem of an article Fred. A fascinating insight and (if I may say so) brilliantly written. Of course the west does have a technically viable source of energy easily capable of replacing oil and natural gas combined and then some....but chooses not to use it - at least for the moment. That is nuclear power of course. We choose not to deploy it to its full capability because of some irrational fear, perpetuated by the know-nothings (and vested interests) of the world. At the same time as we agonise over radiation exposures so small as to be less than that from eating a banana, we glibly talk of invading oil producing countries to secure that asset. Apparently it is OK by comparison to wipe out a few thousand American and British soldiers to secure oil energy so we can drive Hummers ...a sad, sad reflection on our society. Of course the inescapable fact is that whoever "owns" the oil does not change the obvious conclusion that it will run out....don't know when but it will. Nuclear power will never run out. It is unlimited. Once you can produce electricity from otherwise useless lumps of rock you can produce hydrogen from water which the planet seems to have alot of. One carbon atom and four hydrogen atoms gives you methane and every other hydrocarbon known....all from useless Uranium (and Thorium) rock. If you agree that nuclear power is unlimited and will not run out and you agree that water will never run out then you must be drawn to the conclusion that the production of hydrocarbons synthetically is also unlimited. An oil well that never runs dry - ever....all for the radiation exposure of a banana or two. You mentioned the Alberta Tar sands. They produce about 0.5 - 0.75 million bbl/day there right now - not very much on a world scale. But it will grow as more developments (Albian Sands) come on stream. The limit to production is likely natural gas supply and labour shortages but I suspect those difficulties will be overcome. Bruce Power is planning to build Nuclear plants to generate steam to extract the oil without natural gas...indeed Saskatchewan (the Province next door) has also requested Bruce Power to consider building a nuclear plant or two there. In Peace River Alberta (another area rich in Bitumen deposits) Bruce Power intends to build the two reactors. So its not just the Middle East that benefits from high oil prices. Canada is doing very nicely thank you. The growing realisation that oil is not an unlimited commodity is sure to drive the price ever upward and at some point the inexpensive and very safe nuclear energy solution will replace it. As the old adage goes you pay me now or you pay me later but pay me you will. Of course there are those that continue to live the pipe dream of renewables and -just like the lack of understanding of the power of modern nuclear weapons - there is a total disconnect between the amount of energy that can be produced that way and the amount of energy (not just electrical energy) needed to run the world...way too little by several orders of magnitude. To me it's like trying to light up the Eiffel Tower with a flashlight battery. But despite the plethora of facts to the contrary some still cling to that misguided notion. Once again I thank you Fred for a really informative and witty article. Your work is always a joy to read. Malcolm

Just a word of caution to Bob Amorosi. At the outset and for the record I am not against renewable energy quite the reverse. However I am against perpetuating the notion that it can provide even a very small fraction of the worlds energy and I am very familiar with what is going on in Ontario. The unfortunate fact is that installed nameplate capacity is no measure of the amount of ENERGY produced. A trap you appear to have got caught in. While there may be lots of windmills going up there is not lots of wind to keep them running at 100% of their nameplate ratings. Very far from it. Most wind farms are lucky if they make it to 20% capacity factor. You can build a million wind towers but when the wind ain't blowing they make no power. A sad but irrefutable fact. The same applies to solar panels. The Sun - if I am not mistaken - does not shine at night so the best you can do is 50% capacity factor....that is abysmal performance for a power plant and explains why the power costs 10 times more than most other "conventional" methods. Of course that makes the assumption that it is sunny every day of the year in Ontario....and I think you will agree that is clearly and irrefutably not the case. The very best you will get from a solar array is about 25% CF or less. So a 40 MW solar array covering dozens and dozens of acres of land effectively only produces 10MW average. I do applaud the efforts being made - I do believe it is being done with the best of intentions - but it is a drop in the bucket and a very very expensive drop in the bucket at that. If you want a 1000% rise in your electricity costs solar and wind are the way to go....just don't expect Ontario to have any manufacturing industry left. It will convert us very rapidly to a have not Province. Once you get your head around the scale of energy use in this Province and other jurisdictions (electricity, oil, gas and coal combined) you will quickly come to the understanding that renewables are simply not powerful enough to meet the demand. There is only one energy source capable of filling that void and - like it or not - take it or leave it - that is nuclear energy. The rest are simply far too small. Malcolm

Paul Stevens 5.28.08 |
Point well made Malcolm. The whole premise on which rising oil prices are based is rising demand. My understanding is that the US consumes more oil than any other nation, and most of it is used for transportation. A significant portion of that demand could be removed if the rules governing acceptable transport were changed. The structure of North American society is based on a dispersed (relatively speaking) population. Suburban sprawl, a desire for rapid truck based transport, and long travel distances to work have forced the construction of a large network of highways. The federal government has mandated crash worthiness tests and advertisers have promoted the large, living room on wheels versions of personal transport that can only be operated economically on cheap gas. If high mileage vehicles, such as are seen around the world in countries where disposable income is less, were allowed to operate in the US and Canada, what would happen to demand for gasoline? If such lightweight vehicles were allowed, how many could reasonably be operated by battery? If wide spread adoption of nuclear energy kept the price of electricity low, and the North American population were allowed to operate lightweigth electric or gas powered vehicles, would that not change the equation? I am not sure, but I suspect that a lot of people would jump at the chance to purchase personal transport with a roof, heater and radio if they could get 75 mpg (or a days worth of operation from their batteries) and only have to pay $6,000. No reason why such vehicles couldn't be licensed for urban use only, or restricted from travelling on certain highways for safety reasons. A 20% drop in demand for oil in North America could have a significant impact in the price per barrel I suspect. Or maybe it would be taken up by growth in China. Not sure, but I do wonder about the tight restrictions on the type of vehicles allowed on our roads. It has certainly served the big three well for many years.

Build plug-in hybrids (PHEVs) that use renewable methane as fuel. Maybe a small liquid fuel tank too, for range and to connect with the existing infrastructure. That's what we need to do. As Paul Stevens has said, North America has been built into a sprawl, but its not that sprawled, so a PHEV that can go even just 20 miles all-electric could accommodate most commutes, especially if charged on both sides. Yes, kind of a pain, but it can displace a good chunk of our oil use. Of the 20 million barrels of oil used each day in the U.S., 2/3rds of that goes to transportation, and about half of the total (10 million barrels) goes to gasoline. Since we can't easily increase supply, as Fred has shown, we need to reduce demand. We can do this the hard way or perhaps the less hard way. PHEVs are the less hard way. Since the big cost of PHEVs is the batteries, and not the electric fueling, even alternative energy strategies of solar or wind would be cost-effective to the consumer's eyes when recharging a PHEV. (A gallon-equivalent of electricity at $0.20 per kW-hr would cost $2.40.) Distributed generation from even these expensive sources could serve to reduce the infrastructure demands of many PHEVs charging up. Bio-methane is the lowest cost, most efficient, and easiest route of cellulosic biomass to a usable fuel. It easily interfaces with our existing NG infrastructure. It is cost effective NOW, either via anaerobic digestion or pyrolytic means. This is likely to remain the case for some time. Even if someone can get cellulosic ethanol to work, it will likely tie up the technology with some kind of patented microbe or process. Just like what happened with NiMH batteries. Or what probably will happen with Lithium Ion batteries. But bio-methane is an old mature technology, we can do it now. NiMH batteries lose patent protection by 2015. They already have a proven track record with the RAV-4 electrics (good for 10+ years, 150K+ miles). Definitely good enough technology for PHEVs and even EVs. If more goods were shipped by train, then PHEV-style trucks could perform the last 50 or so miles of transport. This would save lots of diesel, and the truckers could still keep their jobs. Trains still use diesel, but they are incredibily efficient with its use compared with road vehicles. So, beef up the rail system too. If broadly implemented, PHEVs + biomethane could destroy up to 9 million barrels/day of demand in the United States. If applied even more broadly, then even more oil demand could be reduced. Enough to buy us some breathing room if we started yesterday. (Yes, that's a lot of nickel used, but spent batteries can be recycled, so it's more of an invested resource rather than a consumed material.) Anyway, I don't know if its a "plan" but there you have it - use our existing infrastructures (NG and electricity) to replace the 3rd one (oil) that is running out.

Len Gould 5.28.08 |
Jim: Just a quick aside re. your calculation "(A gallon-equivalent of electricity at $0.20 per kW-hr would cost $2.40.)" -- that doesn't account for the difference in use efficiency of the energy onboard a vehicle, eg. gasoline at 25% v.s electricity at 90% so the "gallon-equivalent" in electricity will actually only cost about $0.80 or less, even at $0.20 / kwh.
|
|
Len Gould 5.28.08 |
Only real question, for me, is whether there remains the petroleum resources out there to implement one more serious drop in oil prices in order to, once again, kill enthusiasm for alternatives, as 1990's. This one uncertainty is probably the biggest hurdle for alternatives to overcome.
|
|
Len Gould 5.28.08 |
10 kwh energy per gallon gasoline. relative efficiency factor = .25/.90 = .278 2.78 kwh electricity onboard a vehicle can do the work of 1 gallon gasoline. Purchasing 3.37 kwh can probably put 2.78 kwh onboard the vehicle. (85% charger effic.) 3.37 kwh x $0.20/kwh = $0.68 / gallon equivalent.
|
|
Len Gould 5.28.08 |
Of course the previous ignores other effic. benefits of electric auto drives. Energy recovery from braking. Elimination of idling. Elimination of reduced effic. (well below the 25% used) of gasoline engines operated at low speed. And those who will come back with "what about the batteries getting sucked dry by air conditioning need to understand that gasoline auto A/C units are also driven by the engine, and the same efficiency calculations used above apply equally well.
|
|
Jim Beyer 5.28.08 |
Len, Now there you go again confusing things! Who do you think I am, Jeff? :) A gallon of gasoline contains about 35-36 kW-hr/gallon, so I already took that efficiency thing into account. Assuming .3 efficiency, you get about 10-12 kW-hr of electric for a gallon of gasoline. Ethanol is way worse, because it is only about 65% of the energy content (per unit volume) of gasoline. One you point about uncertainty, I don't think there really is any, but the automakers are always gunshy and poor. And bureaucratic. So they lack the vision and drive to implement these needed changes. The answer here is to foster retrofits which should help encourage the automakers to make the needed changes. They just HATE it when they see other folks making money that they could be making. (Toyota is WAY gunshy about PHEVs apparently due to the NiMH patent issues. If it wasn't for them, they would probably be taking a more leadership position in this area.) And just to be a stickler (and conservative) I think one should compare the benefits of PHEVs to HEVs, not ordinary vehicles. Since HEVs are already out there, one needs to justify PHEVs as an additional step from them, not just from ordinary IC vehicles. I think in an odd twist it might be that in quantity, PHEVs might even be less expensive to build than HEVs, but that's another story that I won't get into.

Len Gould 5.28.08 |
argh.... Jeff may be right...

Bob Amorosi 5.29.08 |
Malcolm, You are correct. No one really believes that solar PV and wind turbines will displace the conventional large central generators in Ontario, merely just compliment them. The thinking I believe is that when the wind and sun ARE blowing and shining, their contributions to the grid will result in that much less output needed from the large central stations, whose fuel costs are continually going up. Storage is another big potential. If battery storage technology keeps getting better over time as it has, and if its cost goes down, then there will be energy from some renewables available 24/7, admittedly only maybe only on small scales at first in microgenerators.

Ferdinand E. Banks 5.29.08 |
Gentlemen, in case you missed it, there is a discussion in the latest or next latest Newsweek which contains a discussion between the (former) pro-nuclear Greenpeace boss and Amory Lovins. It reminded me of an expression I once used to describe the members of the economics section of the Nobel Prize committee: dumber than stupid. Fred
|
|
Malcolm Rawlingson 5.30.08 |
Thanks Fred, I don't normally read newspapers but the Newsweek article you mentioned might persuade me to buy it. Not that I am a fan of Mr. Lovins. And I thank you Bob for your comments. Unfortunately there are many people who DO indeed believe that solar power and windpower can substitute for the massive power plant infractructure. In fact many members of the public are quite convinced that the 1.8 MW wind tower outside of the local nuclear plant was built to replace it. I have pointed out to alot of people that it takes several thousands of such windmills to replace a nuclear plant....they still do not believe it and who can blame them when the media continue to promote these low power technologies as "the answer" to our electrical energy supplies. They are not and they never will be. You are also correct that fuel costs are going up. Where the fuel cost is a significant component of the total cost of electricity - as is the case with - coal oil and natural gas fuelled plants - I agree 100%. For nuclear that is not the case at all. Nuclear fuel costs have risen as a result of increased Uranium demand, however the fuel is such a small part of the cost of nuclear generated electricity that a doubling or even tripling of nuclear fuel costs has almost no effect on the price of electricity produced. Nuclear power is almost free as far as fuel costs go. Storage of electrical energy is an interesting topic Bob and yes I do agree that storage will indeed assist with the availabilty of renewables. I have stated many times on various posts here that storage is the key to the usefulness of renewable energy. However should large scale storage become available the industry that will benefit most is nuclear not renewables. The reason is that nuclear is only useful up to the limit of base load on the grid. Cycling of nuclear plants is undesirable (at least the current designs) and it is far more desirable to keep then running at full power all the time. With cheap energy storage available nuclear can increase its contribution because the base load will increase by charging the storage in off peak times. But I do not see the cost of this storage going down any time soon and the exotic metals and materials used in the technologies I have seen will make their widespread deployment very very unlikely. What is a much more likely scenario is the production of hydrogen by electrolysis and the subsequent production of methane. Fuelled by nuclear generated electricity the production of hydrogen is much like a storage device. renewables can benefit from this approach too. But the scale of renewables is far too small to have any significant impact and - sadly - we are going to learn that truth the hard way because we simply do not as a public understand or comprehend the scale of current power plants. Replacing Nanticoke with windmills is not quite as easy as it sounds is it? At 20% capacity factor for wind you need about 10,000 2 MW windmills to replace it and tens of square miles of PV cells. Or just three nuclear plants. I think nuclear is by far the best and most reliable option for a Province with no fossil fuels...the very reason they were built in the first place. Comments appreciated as always Malcolm

Ferdinand E. Banks 5.31.08 |
I received a mail from a gentleman in Austria telling me why I was on the wrong track with this article. According to him all would be made well by horizontal drilling, more exploitation of oil in far Arctic waters, and of course the recent Brazilian 'strike' somewhere in the Atlantic. It is indeed theoretically possible that we will come out on top in this oil game, but these three things will have little or - most likely - nothing to do with it. Horizontal drilling cannot obtain oil that is not there; for the time being talk about Arctic oil is mostly infotainment; and as a commentator in this forum pointed out, it might be ten years before the quantitative aspects of that Brazilian strike can be fully ascertained. Let me tell you how I think this thing should be approached: we need coherent/comprehensive energy policies based on the liklihood that oil is going to be really really expensive, regardless of how things eventually turn out in Iceberg Alley or the South Atlantic. Fred
|
|
Malcolm Rawlingson 5.31.08 |
Fred you are not on the wrong track. Even if you believe that there is more oil to be found (and that it can be found and extracted at a reasonable price) no sane person could agree that the commodity is in unlimited supply. If it is not UN limited it must be LIMITED. If it is limited it will - sooner or later - not be there depending on how fast it is consumed. When there is none left then what exactly does one do then? Would you pose that question to your Austrian correspondent. Of course there needs to be an energy policy that has as its fundamental precept the fact that fossil based energy resources will eventually not be available. At that point some time in the near or distant future the following list of machines will no longer operate bacause there will be no fuel to operate them. There will be no fossil fuelled power stations, no aeroplanes, no diesel engines, no gas turbines,no gasoline engines, no gas powered lawn mowers, no motorcycles, no steel (uses carbon) and the list goes on and on. Only the following energy sources will be available, wind, solar, tidal and nuclear energy. Wind and solar may make a contribution (insignificant compared to total energy demand). Tidal may be more of a contributor in future years but much work to be done on that technology - promising nevertheless. But the aggregate total of all of these alternatives is not very large compared to the sum total of all electrical and fossil energy consumed. All require some type of energy storage to make them viable 24 hours a day seven days a week. And that leaves nuclear energy as the only viable large scale means of replacing all of the energy we use now. And even that source will find it difficult to replace ALL of the energy we use now. Or we use less - alot less. When there is no energy, or the price rises to where only the wealthy can afford it then we will have reverted our society rapidly back to the dark ages. Without a coherent energy policy from our politicians that day is coming much faster than many think. Malcolm

Ferdinand E. Banks 6.1.08 |
Malcolm, I'm pretty sure that I'm on top of this oil thing, but making that gentleman in Vienna understand would not be easy - unless we were in the same room, where other persons were present. Then he would understand - or at least say that he understood. Pardon my French, but in considering my experiences in the educational wars, I would rather try to teach American soldiers who can only add and subtract thermodynamics than attempt to teach many economists with PhDs energy economics. This thing with nuclear is of course amazing. Whether a nuclear reactor is the most flexible piece of equipment in the world is indeed uncertain, but once you have the comparatively inexpensive electricity and heat that a reactor produces, I suspect that you can go a long way where flexibility is concerned. But try to explain that to the TV audience. Fred

Todd McKissick 6.2.08 |
Rest assured, there are many ways of using alot less energy. For starters, we could use motion sensitive LED street lights with PV on their tops. We could inform drivers of impending greens so they could better time their approach to avoid stopping. We could run a DC bus around our houses to eliminate the dozens of 70% or less efficient AC to DC power supplies in all our latest digital (DC based) equipment. We could make use of the .99 to 4.99 mhz of unused internet bandwidth in most households to make a smart grid today, instead of way in the future. We could integrate a point-to-point lightweight maglev rail in a majority of densly populated and high transportation areas which could also serve as a driverless frieght system. We could also encourage more local food products as opposed to shipping it half way around the world. These are all in addition to the efficiency/conservation pushes currently underway. Of the remaining energy needs, we have a number of things available to help meet the demand. We could spread out large scale wind (towers and high altitude farms), geothermal, solar thermal, hydro, tidal and possibly a few others across the landscape as their resources allow. We can't forget the solar thermal aluminum foundries going in in the 'other' countries. On the smaller scale, we could continue with PV and wind, but build up the market for solar thermal and ground source heat pumps while waiting for fuel cells, hydrogen / methane / compressed air and run-of-river turbines to make it. Many of these systems produce capturable waste heat which effectively doubles it's usable energy output. For the still unhappy commuter, there's the HEV and PHEV and the latest round of pure BEVs that rival a porsche in 'fun'. For those STILL unhappy, we can grow genuine gasoline in greenhouses from photosynthesized algae or refine our veggie oil. For rail, we won't need as much to transport as today since my neighbor's train runs averaged 88% coal last year. For them and the airline industry, we can direct our biodiesel towards for their power. Since the personal rapid transit system is private and point-to-point at high speed, I'm guessing air travel will be more limited to overseas. Since storage on a small scale is virtually identical as demand reduction (DR) and distributed generation (DG) is an extension of storage, as far as the grid cares, we only really have DR. No one cares if I shut off my 1000w light or my neighbor kicks on a 1 kw genset. The same is true for large scale systems where hydro can cover peaks better except that there's more of a coherant intelligence behind the timing. What's needed is a way to extend this purposeful decision making down to the small scale where economies of scale (unit quantity vs. unit size) take effect to make a massive collective difference. Currently, our energy is being used in many ways that make no sense at all. How much of our oil, in barrels, goes to move other energy around? How about the daily shipments of fresh alaskan fish to most major cities in the US? How about the truck driver going all over town to fill a load before driving it to another city? I don't even see anyone discussing traffic aggressiveness as opposed to the lame argument of speed alone. We're all in for a long and redundant battle until we start to address these types of issues and dismissing them in favor of any one-size-fits-all approach is purely emotional passion. I say get the government as far out of the game as possible and let the markets decide on all levels what works best for them. I'm sick and tired of paying my middle-eastern counterpart so much money.

Todd, You have touched on many cultural issues as well as what's technically possible to reduce our energy needs, and changing a culture takes a lot of effort read time and money in free market systems. Energy has been so plentiful and cheap to us westerners for so long that we have grown a culture that is pervasively inefficient in so many ways. Getting us off our old habits into radically new ones will never take place in the free markets as long as consumers and businesses have the choice available of using the cheap old inefficient methods. The only way free markets will work to get us off the old habits is when the cheap old methods become too expensive to bear, which is about the only thing good about the current escalation in oil prices. Trouble is the new competitive technologies can't come into the mainstream fast enough before our middle-eastern counterparts get very rich in the meantime. Legacy methods and infrastructures that are inefficient will not disappear overnight unfortunately.

Bob, Agreed that people are set in their ways and won't really make a change until it benefits them. That's why I limited my list to items that are cost equal or cost negative. That is, unless they only consider the next pay period's timeframe, which, unfortunately is how most people make decisions.

I don't have any fundamental disagreement with Todd that there are lots of ways to conserve energy....I probably practice most of them and that we can do lots to make homes and offices more efficient. There is nothing inherently wrong with anything proposed here except that it is order of magintude too little. I just do not comprehend how you run an aluminium plant or a steel plant consuming electrical power in the tens to hundreds of megawatts when it is supplied by PV cells and wind towers that may (or most often may not) be producing any power at all. You cannot shut down a steel plant when there is no electricity - all the furnaces will be destroyed. Electrical storage in the hundreds of megawatts is just not on the cards right now. I think what is at the root of it is a lack of understanding of the processes that modern society relies upon and the fact that they are very energy intensive. All of the gadgets that Todd notes are useful - but they do not grow on trees. Alot of energy is used to make them - very often more than the device will save over its life. The same with storage batteries. Hopefully better technology will come along to allow high capacity storage - but I would not bet the farm on it. Whoever cracks that one will be a bazillionaire overnight. But all of this avoids the basic question that you cannot have the industrial society we live in with renewables and conservation only. You cannot conserve what you do not have. While Todd and I have had this debate before...the underlying principles of why nuclear power is the only real answer is this:- if we are to elevate the living standards of two thirds of the worlds people to anything even close to our own then massive increases in energy supply (100 to 1000 fold) will be required. Solar and wind are not even close to meeting that and we sure are not going to be able to do it with coal or oil without significant environmental damage. Malc

Fred, Yes I can imagine trying to persuade those with closed minds of the need for an energy policy - at least while their lights are still burning brightly every night. But that is the nature of the beast and its probably not worth your energy trying to teach people who just don't want to know. Viennese Ostriches by the sound of it. About flexibility of nuclea plants...the control logic and systems of older generation nuclear plants were not up to making nuclear reactors follow the load so they are all run at base load. With the newer reactors load following is very feasible. Even with that flexibility he large capacity of nuclear plants (modern plants are in the 1000 - 1500 MW range) the economics favour continuous full power operation (ie base load). Pebble bed reactors now being developed and built in China and South Africa offer much higher outlet temperatures and can be used for electrcicty production as well as process heat and steam production and will be able to replace much of the coal oil and gas installations used in many industrial plants for making steam and hot water. But the key to using nuclear to get away from oil and other fossil fuels is to harness the unlimited energy production capability to produce methane on a large scale from hydrogen. In other words connect nuclear plants to the gas infrastructure via the on-site manufacture of hydrogen. That way there is no new "hydrogen" infrastrucure required. It uses what is already there. Of course methane is the key bulding block to the synthesis of all hydrocarbons and therefore the key to fossil fuel independence. It would be wiorth trying to figure out the economics of such a system. It is the only viable way I can see of getting off of the oil bandwagon. No doubt trying to convinve the Vienna crowd of THAT concept would be most difficult indeed. malcolm

Todd, A recent post on the limits to renewables describes one man's efforts and costs associated with installing Government subsidised solar PV arrays on his house roof in California. Clearly this is a thoughtful man and he cannot make such a system pay for itself in a reasonable time frame even at rates as high as 36c/kwhr in peak times. If he cannot make a go of it in Sunny California WITH subsidies and WITH high electricity costs - surely it does not take a rocket scientist to understand that doing it anywhere else is just a non starter economically. And that is without the cost of a battery to power his home overnight. Remember in the ideal world of renewables there can be no other power plants to back up your system overnight. They are all off line shutdown and dismantled. Solar, wind and hydro is all you got. The pay back time in Canada is never. Power rates here are about 7c - thanks to lots of Nuclear Power - and a nice amount of water power (good old Niagara Falls). The Sun does not shine alot (seems like never in the winter time) and its strength is far less than in California. So if it is not economic in California it sure ain't gonna be worthwhile here and Canada is a very big and very cold country. malcolm Malcolm

Todd McKissick 6.3.08 |
Malcolm, Thanks for your comments. Indeed, we have discussed this and it always comes to the scalability sticking point. The problem is that the subsidies greatly favor (possibly even conspire toward) only the renewables that do have the problems you mention. You are correct that PV would have a very difficult time running an aluminum smelting plant but a solar thermal one is not only viable, it has been running for a while now in Uzbekistan. With only backup fuel being occasionally needed, it is proving much better economics than electric plants. Too bad the US has listened too long to those saying it can't work. The reason I keep harping on the subsidies, it that those have overpromoted the PV and Wind you use to measure all renewables against. For those, your arguments are all valid, but for many of the other, they are not. They don't follow the bigger-is-better economies of scale that most energy guys subscribe to. They follow the 'stamp out millions of cheap little ones' EoS. Think PCs and McDonald's toys. Those things are both so cheap that they impacted the market for their larger predecessors. Unfortunately, they have to be perfected which means they have to be accepted by the masses, which unfortunately today, also seems to mean they need government blessing. On the argument that we can't scale any of these up fast enough to make a difference, I refer you to the old 8' satellite dish industry. Those things were a huge capital investment to the consumer to provide independence from a then overcharging industry, and they looked very intrusive. But they sold over 5 million of these things in just a few years and that adoption rate was only bottlenecked by the manufacturing capabilities. This is because financing, assembly, installation, setup and maintenance were all distributed to the local community (or the end consumer himself) and only manufacturing was centralized. Now drop a plant every state or two and add in a few competitors and you've got tens of millions of 1 - 5 kw systems going in each year starting this year. This is the power of the DG industry that's silently growing up around our feet. On financing, if you compare the economics of large scale to DG systems, you'll find a few differences. The large guys will include every last cent in the proposal and fight for that last basis point of interest. The little guys are more subject to emotional passionate decisions, miss adding in the extras and have an easier time raising the project's funds immediately. This makes them more succeptable to less lucrative deals (read that as earlier adoption), but it also provides a larger market for the DG systems manufacturers to compete for. Once again, the free market prevails. No sun in Canada? Hmmm, much of Alberta has the same yearly average (4 khw/m/day) and January minimum (2 kwh/m/day) as most of the midwest USA WITH a colder medium to discharge waste heat to and more domestic uses for that heat. As an engineer, I'm sure you can see this translates to better system utilization of either solar thermal or even some concentrating PV systems. If you still don't want solar, there's wind, seasonal storage systems, run of river hydro, bio-fuels or any of the new systems which still need fueled but are just more efficient. Otherwise, you can stick with nuclear or just have me send you some of my excess. ;) By the way, most of the die-hard, off-grid, remote-living guys that I've followed all live in Northern Ontario and one runs a personal foundry!

It's the attitudes like Malcolm which have gotten societies into this mess to start with. I call it the "big utility" or "engineer's don't create" mindset. No possibility of anything working which hasn't already worked for the past 20 years. Agreed, engineering schools have been in the business of stomping the creativity out of young minds for the past 50 years or so, on the theory that guys calculating stress levels on bridge girders had better stick to the rule books and not be creative. Let someone else do the creating. Problem is, the only other qualified "someone else's" are all too busy writing engineering textbooks and teaching at engineering schools to be creative, so nothing really novel ever gets done.

Jim Beyer 6.3.08 |
Malcolm, I agree with your mindset and viewpoint in general, but it is also a bit of a closed mindset, and thus somewhat dangerous. It's not hard to show the non-economics of PV, but the numbers are much better for something based on solar thermal or concentrated solar. Solar powered water heating is fairly easy to justify cost-wise. And even with PV, what if that electricity was put into a PHEV.? Then even at high electricity rates, it still might displace gasoline economically (albiet ignoring the cost of the battery packs). Another thing that kind of grinds me is when other conservative folks chaffe at the infrastructure cost involved with charging PHEVs yet do not seem to acknowledge the infrastructure benefits that DG such as PV also provide. I agree that nuclear makes sense now, and will even make more sense in the future. Solar and Wind only make sense if their intermittent sources can be used effectively. Smart metering, PHEV charging, and temporally-displaced HVAC (via freezing water) are all examples of technologies that can help make these sources more effective. Conservation is another one. We always seems to forget that one. I also have to voice some of the anti-nuke sentiment (though I am NOT anti-nuke) that if nuclear power is such a great deal, then why isn't the private sector going whole hog and building them? You could argue public sentiment, but again, if they are such a great deal, then why isn't the private sector lobbying and campaigning furiously to the public so they can get them built? Personally, I feel nuclear power plants ARE a great deal, and should be built, but I think the private sector is scared of them. They are so big and problematic to build that they are not comfortable investments for them. Who wants to spend $5 Billion on something that may have a 50% cost overrun? That's just too scary a notion for interests with that kind of money. This is a shame, but nonetheless the case. Say what you want about solar or wind, but at least the investments are in smaller portions.

Malcolm, I heard from that Austrian gentleman again. This time it was about nuclear, and you will be happy to hear that he was in your corner. I also heard from someone at the Rocky Mountain Institute about participating in a conference call arranged by none other than Amory Lovins. Unless I am mistaken, Meester Lovins is familiar with this forum, and if he wants to go to war over nuclear, I am sure that there are plenty of people in this forum who will gladly provide him with the satisfaction he deserves. Fred

Todd McKissick 6.3.08 |
Fred, I had the opportunity to speak with Mr. Lovins in February after one of his presentations. He seems a nice enough guy and very sincere about his beliefs. I found them only slightly narrowed by blinders. For the most part, everything he was promoting was sensible and doable. I know he's against nuclear but I don't know the root causes for that belief. I think it's more based on that we don't need to go down that road if we get our act in gear elsewhere.

I'd like to see a really good updated debate with validated and numerically research data to back up everything as much as absolutely possible. Too bad that the Integral Fast Reactor went through, modern day Gallieo's. What do I know, I was looking at BlackLight Energy today, and thinking, whoa, I'd love to see that prototype

Jim Beyer 6.3.08 |
Bill. The debate about the cost of nuclear power has been beaten around quite a bit on EnergyPulse. Lots of thoughtful people have provided insight on this issue to the extent that (at least in my mind) some things seems fairly clear. Among them: Cost of waste storage is not a significant issue with nuclear power. That being said, it is still not completely resolved, but when it is, it won't cost all that much. Less than half a cent per kw-hr of energy produced. Likewise, the cost of Uranium is not a significant factor, and won't be for quite awhile. Even a 10X rise in fuel prices will not significantly raise the cost of power produced. It's simply to small a portion of the overall costs. The big cost bugaboo with nuclear power is plant construction costs. These are NOT included in EIA numbers, which only cite the operating costs of nuclear power. These are around 3-5 cents per kw-hr, and include fuel, maintenance, and (I think) the cost of waste storage. So, what everyone scratches their head about is, how much do plants really cost, and how much does this impact the overall cost of nuclear power? The good news seems to be that newer plants will last a long time; closer to 60 years than 30. This bodes well that eventually they will be cost-effective generation strategies. The bad news is that cost controls on building these things do not seem to be well-established. The track record is spotty and overruns are common. Many blame excessive regulation. Whatever. This is the reality, at least in the States. All that being said, my own guesstimate is that the true price of nuclear power is probably close to 6-8 cents per kw-hr, when plant construction is amortized into the equation. This is probably high, given the plants could last 60 years, but it's hard to price something out that far. The best future (as a plant owner) would be to get one built and then know, eventually, you will be able to make a lot of money off of it after it has been paid off. 6-8 cents is higher than nuclear proponents would like to claim, but much lower than nuclear critics (like Lovins) would claim. As a result, it probably isn't that far off. If you look at the data, it's hard to see how claims of 14-20 cents are justified. Likewise, claims of 2-3 cents are hard to believe, given the reality of cost overruns, maintenance costs, and fuel price increases. Anyway, just my 2 cents.

Len, Engineers for the most part are realists. We make stuff work. We keep your lights on day after day after day, week after week and we do it so well you complain when they go off for even a few minutes. When you tell me that "solar" or "wind" is the answer or conservation my training and many many years in the energy business tells me to look at the numbers because numbers tell me what is really going on without the politcal spin doctoring. The numbers tell me that Solar energy of any sort CANNOT operate when there is no Sun and that is 50% of the time on average. That means that to make power at night you must store it during the day. That means you must have more capacity during the day to power the day needs aswell as the night storage needs That means you must build a solar facility AND a solar storage facility if you are to provide power round the clock. A similar case for wind. Different conditions depending on wind availability but the story is the same. Not against it but with capacity factors at the best sites of 20% you will need many more than the nameplate tells you you need. Please post on this site a plot of actual electrical output over a year from any wind generator of your choice and plot it against its nameplate rating over the entire year....what it should produce IF the wind was blowing all day and all night which it never does. Perhaps that will convince you and everyone else that wind power is not sufficient. I am not preventing nor would I want to prevent, any one from installing solar panels on their roof or building a windmill in their back yard and I applaud any Government that wants to promote it- go ahead you are free to do what you want. Your neighbours might not be too pleased at having a view of your 50 foot windtower outside their living room window. But even with incentives I do not see hoards of people doing so. I can only assume that it is either too expensive or the way that electricity is currently provided is the better choice for most people. In Canada they would spend most of the winter brushing the snow off them. I cannot envisage the average senior citizen climbing up on the roof to brush off their solar panels before the fridge will work or the lights will go on. Might be OK for Todd but the average person - not a chance. And of course you missed the whole point of the discussion that sooner or later fossil fuels will run out. It is not a maybe - they will. and there must be a truly viable alternative available when that happens or we are all in trouble. Fred raised the issue about energy policy and my argument is that some thing must be capable of replacing ALL of the fossil fuel energy supply AND the electrical energy demand. Neither solar energy, wind, nor conservation can do that. Not even close. The point was raised above that private companies are not rushing to build nuclear power plants. I beg to differ. In Canada, Bruce Power - a private consortium - is planning to build two nuclear plants (privately financed) in Alberta and possibly one in Saskatchewan.They are already refitting four power plants using private money. They also want to construct another plant at the Bruce Nuclear Site in Ontario....plans for this number of provately financed plants hardly supports the notion that they are not economic. The are a very economic method of producing large amounts of electricity, hydrogen and heat safely and cheaply. Numerous private corporations are planning construction in the US. Many countries around the world are rapidly building up their nuclear capacity. So the argument - often repeated - never verified is that no-one wants to build nuclear. Plain wrong. The good thing for the sane people of the world is that we (lowly engineers) know how to build an operate nuclear plants we do now and we will do in the future when there are hundreds more. Call me closed minded if you will but I'd sooner have a closed mind and provide reasonably priced energy to 6 billion people than an open one sitting in the dark waiting for the wind to blow. Malcolm

Todd, Great response...I always enjoy your comments and feedback thank you You forgot one thing. It snows in Canada - alot. Darn stuff covers up all your solar arrays and energy prodcution drops to nuthin on cold snowy days. Perfect. Who pray tell is going to get up on the roof top and brush that lot off. Not your average 85 year old grandma for sure. My son works on the tar sands in Northern Alberta. Unless you're burning wood you are going to be very cold in the winter up there. In Ontario we just about exhausted all our water resources - it is why we went for coal and nuclear - no hydro power left...There is a bit more we could exploit but really not that much even on a small scale. wind and solar will help - but not much really. You also must bear in mind that being "off grid" is OK for the fit and able bodied but that is not everyone. I am quite sure my Mom would not be able to keep these systems running in her home. She would not be able to survive. And it is not just the elderly what about the sick and injured and disabled folks in our midst. Home based systems are fine for the likes of you and me with an interest in these things but on a larger scale using this approach for everyone is unlikely to work. Interested in the size of the Uzbekistan smelter. What is its output in tons of aluminium per day? Alcan (I think) is building a plant in Iceland...wonder why they went there and not the dessert to build a solar thermal one. Maybe they missed something. And I am curious to hear your opinion as to why developing countries like China and India (who essentially have a clean slate) are building large power plants on an unprecedented scale. One large coal plant a week coming on line in China. If solar or wind or small scale anything would do it why are they NOT doing that. Sure China is also building wind farms and solar arrays but the bulk of their electricity will come from coal and nuclear. If small scale was "growing up all around us" you'd think they would be the first to be doing it. So explain to me why they are not? Perhaps their engineers have been brainwashed by the engineering colleges too. Maybe the University of Bejing is in cahoots with US universities to ensure the golden truth about wind power and solar does not get out to the public....I smell a conspiracy....Or could it be that they crunched their numbers just like we did and came to the same conclusion - Nuclear or coal and when there ain't no coal left....well leave that to you to figure out. Malcolm

Todd If Josef Goebbels said the things that Amory Lovins says, they would be called lies. I think that 'misunderstandings' is appropriate here. The most important for me though is that he did not reply to the criticism he received on the two articles he published in this forum. Perhaps just as important is the simple fact that while his "doable" proposals might be just what the doctor ordered on the rim of the Kalahari, they dont make any economic sense at all for this country (Sweden). By the way, I was informed that Dubai is not a country, and according to Google it's an 'emirate'. I suspect that emirate means pretty much the same as country, but in the future I will call it an emirate.

Len Gould 6.4.08 |
Malcolm: The raw economics of solar PV today may not make sense, agreed, but we all already knew that so what's your point? Other systems however, like micro-CHP solar thermal cannot be so easily dismissed. There is simply no technical or economic argument that you can make which will prove that such systems cannot be implemented economically, certainly in high-insolation areas od the west (clear daytime skies is the biggest factor, not latitude). Certainly steam or Stirling engine technology is theoretically capable of electricity generation from such, and at today’s electricity costs, or those which will apply the first day Bruce Nuclear’s first reactor hits the SMD market, these should be do-able. Micro-solar thermal CHP with bio-fuelled or N Gas or propane backup (for grandma) should be able to generate electricity at lower costs TO THE OWNER than purchasing from a market where the minimum price is set by the newest baseload nuclear. But we'll never know, will we? We'll more likely all be frozen in the dark by the time you engineers figure this out yourselves, then spend twenty years undoing all the stuff you've convinced the boardroom members of so you can finance another twenty years of needed actual development work on the engine and collector technology, and associated manufacturing technology, building integration technology, automated cleaners etc. etc., then get past the errors always made on introduction of a new technology, etc. And it would also help if some metering technology engineers got a clue as well, because without a market, none of this can actually happen, but that's another whole topic. If a (very near-term likely) breakthrough in fabricating optical rectena PV panels with (theoretical >50%, likely >25%) efficiency at the price of a few ounces of carbon and some wire and plastic, happened tomorrow, the inventing company's management would likely fire the developing scientists because there's no market for such systems, no infrastructure of PHEV battery systems to absorb the peaks, and their engineers have told them it'll never make sense. (Many or most) engineers are just far too conservative and narrow minded, and have no view of the future. I know, I work with them too, though I know of a few rare exceptions who never get anywhere in hierarchical systems. BTW regarding wind, I am agnostic. I can do the same numbers you do, but am prepared to grant that just maybe T. Boone Pickens might just know something I don’t. And yes, I should spend more time on the grammar and spelling of this, but I loose patience with spellcheckers which insist that nuclear must be spelled nu {space} clear.

Bob Amorosi 6.4.08 |
Malcom: it’s obvious to most of us engineers that solar and wind distributed generation will likely never replace most base-load large central nuclear or hydro stations, and are not yet practical as you say for absolutely everyone to have on their rooftops, especially IF one thinks that the homeowner must maintain them. Granted our elderly mothers may never be able to clean snow off them in winter, but many seniors will pay someone else to do it for them just like they pay young kids to shovel their driveways. Even better, there may be an opportunity for someone to develop a heating system to melt the snow automatically, and once melted the sun's heat will keep it clear just like my black asphalt driveway stays once it is cleared (until the next snowstorm of course). Solar and wind discussions should be divided into two areas really to avoid confusion; the rooftop systems for individual residences, and secondly the large farms out in rural areas or on lakes. There are many large scale solar and wind farms being built with the full expectation that they will operate only part time, expecting the grid to buy their output when available. Once their construction costs are paid for, their owners will have virtually free energy fuel sources on a part-time basis, and expect to make lots of money I'm sure. It's why they are lining up to get signed onto contracts the Ontario Power Authority has been doling out. Consider this - if rooftop systems were deployed for even only say 20% of residences, what would the net reduction in total grid demand be during the daytime on a hot sunny summer afternoon. It would make the reductions from everyone replacing lights with compact fluorescents pale by comparison.

Some points: Alcan built their smelter in Iceland because of the free geothermal energy available there. Lovins is dangerous because he's a charming, charismatic, and persuasive speaker. And he's about 70% wrong. He's wrong about carbon fiber, as it is still too expensive for automobiles. It's barely economical for passenger jets! Maybe in 10 years it will get cheap enough. He's wrong that nuclear power is too expensive, because he dismisses the storage issues w.r.t. intermittent sources as has been mentioned above. He's right about conservation ("negawatts") but again is not practical about implementation. He was WAY wrong about hydrogen, but doesn't talk about that so much lately. He's a late convert to PHEVs. I asked him a simple question when he spoke in our city: "Will PHEVs supplant the hydrogen economy?" He babbled on for several minutes and never answered the question. (BTW, the answer is YES.) I think the only bad agenda that Lovins really carries is face-saving. I think if you advocate something for a long time, and then figure out you are wrong, you need to face up to it. He, GM, and the NHA are about the only voices left still advocating hydrogen. This energy stuff is tough stuff, so it's easy to get mixed up. But we can't afford going down the wrong path when we know otherwise. He should be better about admitting his mistakes and moving forward. Finally, I wonder when nuclear advocates are going to admit that global warming is the single best thing to happen to their industry in 30 years? Wipes 3 mile island and Chernobyl off the slate. It's clean again! You get a free re-do. Don't blow it this time.
|
|
Len Gould 6.4.08 |
Jim: Lovins is likely not wrong about carbon fiber, simply a bit too early. And if auto companies had listened to him 10 years ago on that one, the volume production involved would probably have the costs down to at least competitive with metals, even given that metals prices would now be much lower. Sure would help with fuel mileage also...

Bill Corbin 6.4.08 |
Thanks for the reply Jim. In your estimate, did you include the 100 or so reactors built during Reagan ? I know the construction management results are superior, probably learning curve benefits. But for the nuclear power industry, it seems to me that 3rd generation and earlier reactors are done (especially 1st/2nd gen hybreds Chernobyl), its got to 4th generation now and start the clean up while simultenously contributing to climate change. I personally do not think that fusion is here, but I'm all for trusting and verfiy. On a related note, I see that defense/space industry has lost its capacity to calculate a critical path, there's alot damage that has to undone from the post 1992 reigmes. I'm just not sure that it happen, the K-car/computer industrial complex wants to believe in solar just like Icarusus (excuse my spelling errors).

Len Gould 6.4.08 |
Bill: Jim's number appears to be in line with stated costs of current proposed builds, eg. multi-repeats costing "in the range of" $2,500 to $3,000 per kw. The numbers I did (unofficial) for a 4,400 mw ACR1000 plant came in at a production cost of "about" $0.08 to $0.09/kwh cost of production to the bus. Selected financing costs are everything though....

Len Gould 6.4.08 |
Malcolm: For balance, here's a perfect example of the dumb things we need to stop doing, fast. Clearly they're not both correct, but neither is clearly wrong. Nuclear power plants are financially risky given high costs -- editor -- mongabay.com, April 4, 2007 Clearly the first is biased against nuclear, and makes several unsupported assertions. But the second is no better, and nuclear proponents need to do better. Attacking CSP is the wrong approach.

Jim, Since carbon fiber is really only oil pitch heated in the absense of oxygen, is it really too expensive or is the technology just sitting idle collecting the low hanging fruit? In looking at bringing it inhouse last year, we found the big expenses to be the molds, oven and energy. All three of those are minimal in mass production which seems to be why my neighbor kids now have CF hoods and spoilers on their cars and CF skateboards. I just can't believe that on a production scale like GM has, it can't be cheaper, mine-to-melt, than steel. What would be believable is that the molding cost is exponential with size - hence your aircraft body statement. Regarding Amory's presentation, perhaps he learned from your question and has since toned down the hype. Bob, Your idea to heat the collector for snow removal is already in the plans on at least one upcoming system that I know of. An interesting discussion comes up from the question of what percentage of homes could actually make use of renewables. You suggested 20% which may be either high or low, but there's another consideration. Small businesses effectively can be counted as a residence with minimal loads 2/3rds of the day. They can still take advantage of CHP features and some efficiency improvements too. Medium businesses up through commercial and industrial can use these benefits as well. With 107+ million families in the US, we could guess that there's about 60% single families. With the average 5 workers per small business, how many of those rooftops are there? How about WalMarts, schools, Costco's and Tee shirt factories? Should we try to find out the total roof space and apply 20% to that or to just the sunny single family homes with a large south facing roof? In trying this a while back, I estimated over 1000 sq. ft. of rooftop per capita. Anybody else know any further info?

Bob Amorosi 6.4.08 |
Todd, I tend to believe your comment about CF production costs being comparable to steel. We don't see the auto industry using CF in a big way in spite of it for several reasons. I am from Canada's steel industry city, Hamilton Ontario, and can speak from experience. The globalization of the steel industry happened before the 1980's which eventually brought about huge competition for North America's steel producers, and ultimately its widespread decimation. The Canadian and American producers have shrunk to a shadow of their former size, with steel prices behaving as pure commodities suffering deflation over time. The only ones who have survived and prospered are those that developed higher quality steels for automotive applications. Dofasco in Hamilton has had a longtime PR logo "Our product is steel, our strength is people" to advertise steel's best quality for automotive use - its physical strength and that this conveniently satisfies government crash safety regulations. Another consideration is the world-wide steel industry already has a huge foundry capacity in place, paid for a long time ago. To put up similar scales of production for CF in auto applications would cost billions (I think) that most investors will not touch when there is cheap steel available everywhere already. Conversely the investments required to build production facilities of hockey sticks and other high profit consumer items in much smaller volumes is considerably less. So this is where you see investment money go into first, the ones with smaller risks.

Todd, the North American auto industry is also not liked by many of its component suppliers. The competition for suppliers is so fierce from the far east that some suppliers simply get out of supplying the auto industry altogether because they cannot make a profit operating in North America. To give you some idea, I work in the electronics industry and have dealt with automakers in past. Their purchase philosophy is simple for a new product you have designed and are ready to produce for them. They tell you OK I will buy your product from you today if you set your price at a level they specify, but you MUST also implement a price reduction plan to lower your price next year and each year afterwards. If you don't like our starting price or refuse to implement the price reduction plan, fine, they will take their business elsewhere.

Thank you for the reply Len. I'll check back in 09-10, and see how the public debate has changed. Doesnt seem terribly 'expensive' to me to convert spent rods and A-bombs into fuel, electricity,etc. Theres only 10,000 years worth of the stuff that needs to be cleaned up. I'm sure the K-Car/computer industrial complex and the electrical engineers within will figure out how to minitaturize frequency regulators and goverors someday, until then looks like same old same old to me.

Todd, I think you explained the problems with CF for cars in your comment. Molds, ovens, etc. That's just a very different (and slower) process compared to a metal press with a single die that can punch out hundreds of doors per hour. Each CF piece has to be in each mold for how long? 12 hours? So 500 parts per day means 1000 molds. That's a lot of money. Plus, new molds are needed for every part change, and dozens or hundreds of molds are needed for each car. I don't think you realize the cost pressures on automobiles. Gas will have to get a lot more expensive for CF to make sense, or they need a better way to make the parts. Aluminum parts are still rare in cars, for the same reasons, and that's a much simpler switch than carbon fiber. One could argue (well) that HEV and PHEV technology would better benefit from reasonably-priced ultracaps to increase regenerative braking. Then the weight of the vehicle would be less critical with respect to fuel consumption. And the same ultracaps could be used in all car models. The economics of aircraft (weight, weight, weight, fuel, fuel, fuel) favor lighter materials much more so than cars.

Todd McKissick 6.4.08 |
I think we've pretty much nailed down the issues with using CF in cars and it amounts to which side of the line you're on. If one believes that improvements in making parts from it are too expensive then you won't support it. This is the state of the art today. If, on the other hand, one believes that with an coordinated effort to go that way, you'll get that high tech process you desire, then you would most likely agree with Mr. Lovins. Personally, I am on the fence since I haven't researched the latest progress for a long time, but I am mostly looking his way. I think most of these improvements that are mentioned on this forum are worthwhile and could actually be implemented in cost comparative manners but the imbalance of support (both subsidy and promotion) is hampering all but the most creative individuals. We're only seeing those systems make news when we could be seeing them skyrocketing and seeing their lesser known counterparts making news. That's the mix I want to be able to pick from. Right now it seems we can only choose from clean coal, nuclear and one distributed method which has many problems - PV.

Carbon fiber. It so happens I supplied some of the original industrial computer equipment to Boeing on their original carbon fiber implementation (mid 80's). They start with a device that CREATES the carbon fiber. Then this incredibly sophisticated machine spits the line out and it falls through the air, cooling as it falls (about 5 stories). The machine points the line at extremely precise angles (tolerances of 1/10,000th of an inch) and as it falls, it effectively weaves a blanket even though it is only one mono filament, miles long. In fact, my company's computer system actually drove the thing (thankfully I had no hand in programming it). Now you have the composite fiber base, but of course it would just un-weave in a second, like pulling a piece of yarn out of a sweater. Therefore, you need the incredibly expensive and sophisticated epoxies and resins that can be cured in expensive vacuum heating chambers to help you mold the design you want. Pound for pound it is vastly stronger than steel, but as Bob was stating, it is no picnic to be on the receiving end of a steel vs carbon fiber collision. On race cars, where they start with the high strength steel roll cage, this isn't such a bad thing, but passenger cars have a long way to go to reach that level of sophistication. BTW, all those resins and epoxies that I know of are based on fossil fuels.

Look at all of things that can be done with cheap fossil fuels. Which one of the military-utlity-industrial complex will be the first one to consumers a choice to purchase electricity by burning A-bombs ? And, then list out all of the over-whelming environmental benefits. Somebody needs to create a lobbyist/business group for Future Nuclear Power Operators.

Len, In 'theory', a selected financing could operate with 'carbon offsets', renewable energy credits, sulfur & nox allowances, and a well focused consumer education program. The fuels could be vintages like , 1945 to 1950, etc...and the forward curve would probably be about 60 years. Bernake would love it.

Ferdinand E. Banks 6.5.08 |
With all due respect Bill Corbin, this is hardly the time and place to be concerned with the loves of Mr Bernake. Shortly after assuming office he announced that there was no need to be worried about an escalation of the oil price, because the futures price did not lead to this conclusion. Unfortunately, the liquidity of the (distant) maturities he seemed to be thinking about was such that only someone who had no practical knowledge of futures trading could arrive at the conclusion that they could provide usable information about the oil price in the future.

Fred, perhaps you're correct again. This week the first set of atmospheric micro-burst touched down right in DC's back yard, they're lucky they didn't get some tornadoes. Its a matter of time now. If my model is right, then, another record setting hurricanes will reach DC and NYC within the next 5 years. The K-car/computer/electrical engineer/regulatory industrial complex has had 16 years to catch up with science, the science that they outlawed. I think, that if they cant get it together within the next 4 years, then the Lincolon's greenbacks will need to start up 4th gens on some bases and start cleaning up. Demand side management will become an 'all you can eat'. Full disclosure - Will vigourously short the dollar as required.

Fred, For your amusement, this recent Fortune magazine article. Enjoy. BTW, they have it wrong in the article about silver (at least) since that price was caused by the infamous Hunt brothers and Nymex' manipulations. I do agree that there will be demand destruction caused by economic downturn. Demand destruction will be good, to a point, then it gets bad, very bad.

Ferdinand E. Banks 6.8.08 |
Thanks Jeff That was a moronic article. Let's get something straight here. According to somebody they are producing oil from shale somewhere in the Dakota badlands. I really wish that I was up there with them, producing and pocketing some of that long green. Of course, they probably dont produce more than enough oil to keep your limo in the fast lane, but that's another matter, isn't it. They are still pocketing the folding stuff, aint they. As pointed out in my article, the big oil producers are in the driver's seat now. Period. There will be some demand destruction due to the macroeconomic thing, but they could ride that out if they were are smart as you and me...well, at least you. Outside of that, Fortune has always been one of my favorite publications, but they have this annoying way of getting things about oil wrong. I wonder why? Fred

Jim Beyer 6.9.08 |
Thanks for the article, Jeff. Just read "The Long Emergency", which I think is about 80% wrong, but at least it's a thoughtful look. The author James Kunstler is obviously a huge fan of both Tom Wolfe and the movie "The Road Warrior". It would seem to me that until we get off oil in a big way, the production peak or plateau will continue to stifle economic growth. So we might stall, producing demand destruction, but when we start up again, we will hit this wall of finite oil production, and stall again. And on and on. Subsidized oil consumption by India and China are not going to be particularly helpful in this scenario either. I would think if there was extra capacity to be released to capitalize on the high price of oil, it would have been released by now, don't you think? Instead, oil futures remain in contango. If we can get PHEVs working, that might buy us 10-20 years or so, but then we will be back in the same boat again.

This has been one of the better experiments in spatial economics that I've seen in a while. After its run its course, and I measure that by looking for dratic collapses in Tier 3 govts (local), Tier 2 govts (state), and finally Tier 1 instabilities, well, Lincoln greenbacks. The sun always rises but it doesnt always shine, and the wind always doesnt blow. Storing air, Hilsch-Ranque vortex tubes. I expect demand curve destruction to end when science is decriminalized in the US. It could take a while. Saw the FERC this morning , 'we need demand elasticity in elecrtricty'. Try it out food first, see what happens. Co-ops Isarel is bluffing

I get RSS feeds on multiple oil topics that interest me, and this one - Oil Fundamentals recently popped up. It is a good description of current leading to future events. He makes a fair point in the article about refining, which has been the overlooked elephant in the room in the oil discussion. The inelasticity of supply and demand being the obvious element. What no one seems to understand is the vastness associated with the oil industry worldwide. That industry is moving a LOT of physical product from oftentimes remote and barren locales against staggering logistical nightmares. So it doesn't really matter that there is oil in the Bakken formation, unless and until all the infrastructure exists to get it to (1st) the refinery and (2nd) your car. And "it",/b> is a LOT of product. Pipelines are good, but they take years (decades in the case of the North Slope) to design, permit and build. Once installed, it is a non-trivial problem to "jump on" a pipeline that might be going right by your new production play. Those tanker trucks you see plying their loads down the highway carry a trivial amount of product, the biggest of them only hold ~200 bbls. Therefore, even if you discover a million bbls per day well in North Dakota, how many trucks are needed to carry it to market until the pipeline gets built? I can't say this often enough. The oil industry is vast, and has had 150 years to get this big. There can be no palliative or replacement overnight for the simple fact that 150 years of experience, infrastructure and investment CANNOT be replaced in a short time frame. Period. Meantime EVERYONE needs to do EVERYTHING they can think of to alleviate the problem on the demand side, and do so for about 50 yrs or so, while the (market chosen) replacement gets traction and wins because it deserves to, not because some politicians took a bribe. Fred, I'll be talking to the oracle of oil in a couple of days, any words of wisdom you'd like to impart?

The oracle of oil. Is that what they are calling me these days? Well, tell the guy or gal that you will be talking to to read my article, memorize it, and sprout it from every soapbox between the Bay of Fundy and the Capetown Naval Yard. I dont have a copyright. More oil in the Dakotas and Montana than.... I wonder who is going to get rich on that lie. I just wish it was me. A condo Aspen or Monaco would suit me fine. Fred

Bill Corbin 6.10.08 |
Tell the 'Oracle', that there's still about 2 generations of people in the US, who havent had the pleasure of marketing gas with a sidearm and a German Shepard yet. $10 a gallon is fine with me, but there would be so many people in the situation the 'work didnt pay anymore.' Wind, solar, sounds like a page turner for sustaining GDP at 0.8% annually to me. I'll be back, when science gets decriminalized.

Jim Beyer 6.10.08 |
Oracle of oil is either Arjun Murti or T. Boone Pickens, right? Questions/Comments I'd ask/make: 1. How do wind farms really integrate into baseload generation? 2. Will PHEVs really disrupt grid infrastructure in the near term? 3. Should we be buying railroad stocks like Warren Buffet? 4. Why is methane (even renewable methane) reviled as vehicle fuel?

Bill: "We will find neither national purpose nor personal satisfaction in a mere continuation of economic progress, in an endless amassing of worldly goods. We cannot measure national spirit by the Dow Jones Average, nor national achievement by the Gross National Product. For the Gross National Product includes air pollution, and ambulances to clear our highways from carnage. It counts special locks for our doors and jails for the people who break them. The Gross National Product includes the destruction of the redwoods and the death of Lake Superior. It grows with the production of napalm and missles and nuclear warheads.... It includes... the broadcasting of television programs which glorify violence to sell goods to our children. "And if the Gross National Product includes all this, there is much that it does not comprehend. It does not allow for the health of our families, the quality of their education, or the joy of their play. It is indifferent to the decency of our factories and the safety of our streets alike. It does not include the beauty of our poetry, or the strength of our marriages, the intelligence of our public debate or the integrity of our public officials... the Gross National Product measures neither our wit nor our courage, neither our wisdom nor our learning, neither our compassion nor our devotion to our country. It measures everything, in short, except that which makes life worthwhile, and it can tell us everything about America -- except whether we are proud to be Americans." 1968 speech by R FK 3 months before shot. Hasn't been a candidate who "got it" since.

Todd McKissick 6.10.08 |
Jim, You're correct in that the Oracle is indeed Mr. Murti so oil and gas related questions might prevail. This is the guy made famous for predicting oil to reach major prices that have now come to pass. It was he who applauded traders for running up oil and denies that any of his wildly overreported predictions had any self fulfilling aspect to them. His motive for the praise was that it will send a message to people to conserve or buy more efficient. I'm sorry, but many people are not in the category holding that option. Since running up this market results in OPEC getting more for their barrel, the traders getting higher margins while remaining under the radar and the oil companies attracting windfall tax hearings to their spoils, why wouldn't he want it to be self fulfilling. It's like Prof. Banks always says - who would do something to help themselves make less money? I'd have to ask him how much he's made on the 'super spikes' he's predicted and how he can sleep at nights. If he was as serious about being 'green' as he says, he would more likely donate, not invest, to promising technologies. I don't see him doing that.

Jeff Presley 6.12.08 |
Todd, everyone who's anyone knows the oracle of oil is none other than T. Boone Pickens. Jim, didn't see your email in time but I did hand him a paper written by one of my partners on wind power, either he'll read it and get back, read it and not get back or not read it at all. ;) Given the opportunity, I'll query him your points and see what he thinks. Fred, if you were willing to come back stateside, maybe you could take a chair at OSU, Boone's alma mater. You'd be amazed how much he agrees with you or vice versa. His idea is to begin to use wind power to replace the natural gas consumed in electricity production. That replaced natural gas can now be utilized for transportation purposes and he happens to own a company doing natural gas filling stations. Less pollution, longer engine life, less imports etc. Don't know if you can see this link or not, but here's some of the talk he gave.

I have been away for a while but I just could not resist informing all those who keep telling me that no-one is building nuclear plants any more that the Ontario Government has decided to build two new nuclear power plants at its Darlington site on Lake Ontario. The Ontario Government has taken a balanced approach and has placed huge emphasis on conservation and renewables but even then it still comes down to a choice between more coal or more nuclear powered electricity. As much as we would like to think otherwise the fact is that nuclear power plants provide low cost reliable electricity with very high capacity factors in very large quantities. Of course I am hoping that the conservation measures will live up to their promise...and the same for renewables...but I doubt that they will at least not without a massive and painful decrease in the standard of living we all enjoy. Ontario is constructing one of the largest solar PV arrays in the world (40 Megawatts when the sun is shining brightly - 0 Megawatts at night when the sun is shining brightly on the other side of the world). The cost of that electricity is 42 c/kwhour versus the average for Ontario of about 5 c/kwh....800% more expensive. At that price nuclear generated electricity is a quite a bargain. On a world wide scale it has been estimated that over 1400 new nuclear reactors will be needed in the next 20-30 years...just to keep up with demand and replace the present reactor fleet and I suggest we better start building now. One commentator up above here noted that it took 150 years to construct the oil infrastructure and it cannot be replaced overnight with any thing. I agree but we can easily build enough nuclear infrastructure to replace oil in much less time than that because most of it is already in place. In my view the oil industry has done a remarkable job of building an infrastructure that powers most of the world...but I think even their engineers as talented as they are will acknowledge that the resource cannot last indefinitely. Sooner or later we, as a world community, must come to grips with the reality that fossil resources are not going to be there forever and the only sources left will be wind, solar, tidal and nuclear energy. Of those only tidal and nuclear come anywhere close to meeting the present world energy demand let alone a future where everyone aspires to the North American lifestyle and its attendant massive consumption of energy. Fortunately Ontario understands that reality. Our friends at Bruce Power are forging ahead with bringing all of Bruce A reactors back on line so, as much as some might erroneously espouse otherwise - the nuclear industry is very much alive and well in Ontario.

Len, Thanks for the links. Interesting reading. Dr Wolff seems to be something of an idealist....a bit out to lunch if you ask me. I cannot envisage the Governments of France and Germany...or any other European Government... basing their whole electricity supply in North Africa....not exactly the most politically stable part of the world I think you would agree. Somehow I think Mr Sarcozy (not sure I spelled his name right) would not agree with that solution. Maybe locate the solar arrays in Spain perhaps...but France has been doing work in the area of solar mirror farms for years and decided to builf dozens of nuclear plants anyway...I wonder why. Perhaps they know something Dr. Wolff does not. And of course I am assuming that, when the Sun goes down in North Africa, that the output of these solar electric generating stations will drop to zero and the large storage systems (conveniently NOT mentioned by our dear Dr. W) will kick in and seamlessly supply the overnight energy needs of Paris, Munich, Berlin Hamburg, London, Glasgow, Edinburgh.............that is gonna take more than your average AA battery. That is one gigantic storage device. Not in a million years. Like I said - out to lunch. The man seems to get mixed up with nuclear fuel costs and construction costs of nuclear power plants. As I have said numerous times here nuclear energy is very insensitive to fuel costs. It is true that Uranium costs have risen...largely due to a supply-demand imbalance but there is lots nuclear fuel available and even if it became 10x more expensive it will not affect the cost of electricity that much. Nuclear construction costs will rise but the counter to that is that mass production reduces costs and we have yet to see the benefits of that in the nuclear industry -except maybe in France. My main beef (and I do have a few) with the nuclear business is that it has got to shake off the idea that every power plant has to be one-of-a-kind hand built Lamborghini. If you want to realise cost savings of mass production you have to build blocks of 10 or 20 or 50 all EXACTLY the same. No country with the exception of France has come close to doing that so the real costs of nuclear power plants should be drastically reduced. It is therefore quite wrong to base the future costs of nuclear plants on the costs of past nuclear plants. It is one of the reasons I favour the pebble bed reactors of South Africa and China. These can be factory mass produced and deployed anywhere. The questions that the public should be asking is why nuclear plants cost so much and what is the industry doing about reducing those costs. I am quite sure that a cost of 1c/kw hour is entirely achievable by the nuclear industry - provided it gets out of the one-off mentality and catches up with the rest of the manufacturing industry that has used mass production for nearly a hundred years.

Jeff...nice idea about using wind to replace natural gas. Nat G plants are used mostly as peaking power supplies (they are way too expensive to run on base load) so my question is how do you get the wind to blow at exactly the same time as the peak power demand? The only way that will work is if you also have a storage device A better idea would be to use the wind energy to make hydrogen from water and then combine the hydrogen with carbon to make Methane. You can store methane quite readily...we do it now...then you don't need natural gas at all and you can use the existing natural gas infrastructure to distribute it. Seems a much better use of intermittent sources to me. Doubt the economics would make any sense though....it would as a fuel for vehicles but not for replacing Nat G in gas turbines....not 100% efficient Thoughts. Malcolm
