Diversified Renewables -- Florida Looks to Mine Ocean Energy

By Howard Hanson, Ph.D, Professor of Geosciences, Florida Atlantic University, August, 26, 2009 - Because energy use in the United States is so dominated by fossil fuel combustion -- the Department of Energy estimates that dominance at about 85 percent -- it is not an overstatement to suggest that the country has nearly all of its energy eggs in a single basket. The fact that a significant portion of that basket, the half or so holding the petroleum, is woven together with a fragile political alliance involving the volatile Middle Eastern oil producers makes the metaphor all the more compelling. more...

Looking for 200 Gigawatts

By John Kemp, Director, Offshore Wave Energy Ltd., July, 22, 2009 - The excellent summary of the ocean power scene by Peter Asmus in Issue 6 of the Energy Central Renewables Topic Center highlighted a number of matters that are of increasing importance as ocean power technology matures. At one point, he suggests that up to 200 GW of marine renewables might be developed by 2015 if U.S. and European targets are to be met, with over half being provided by wave energy. more...

Canada's Geothermal Potential: Learning from the U.S.

By Craig Aspinall, Public Policy Manager, Western GeoPower Corp., July, 08, 2009 - Canada has literally been a `powerhouse' of energy resources for decades with hydroelectricity, natural gas and oil playing a major role in the nation's economy, but only recently has begun paying serious attention to the potential for electrical production from geothermal energy to help meet the demand for "green, renewable" power in the western provinces and western U.S. more...

New Kinds of Hydropower Spark Buzz

By Peter Asmus, Analyst, Pike Research, June, 24, 2009 - While the total installed capacity of emerging "second generation" marine hydrokinetic resources -- a category that includes wave, tidal stream, ocean current, ocean thermal and river hydrokinetic resources -- was less than 10 MW at the end of 2008, a recent surge in interest in these new renewable options has generated a buzz, particularly in the United Kingdom, Ireland, the United States, Portugal, South Korea, Australia, New Zealand and Japan, among other countries. It is expected that within the next five to eight years, these emerging technologies will become commercialized to the point that they can begin competing for a share of the burgeoning market for carbon-free and non-polluting renewable resources. more...

Marine Renewables Make Some Headway

By Bill Opalka, Editor-in-Chief, Topic Centers, Energy Central, May, 27, 2009 - Slowly but surely, energy produced by the waves and tides is gaining some measure of momentum as a viable alternative source of power. At least on the policy front, marine renewables have gained greater visibility in a series of recent decisions, proposals and legislative acts. more...

Geothermal Development Expands Globally

By Tim Stephure, Analyst, Emerging Energy Research, May, 13, 2009 - Tapping a long, successful track record and a growing urgency to increase renewables generation worldwide, geothermal project activity is escalating significantly after relatively slow growth over the past two decades. Attractive for its unique combination of baseload power, cost competitiveness, and zero emissions (at least with current technology), geothermal power is gaining increased attention from governments and the private sector as a renewable generation technology with scaling potential. more...

RITE Project Demonstration Completed, Build-Out Preparation Underway

By Aaron Hernandez, Communications Manager, Verdant Power, April, 21, 2009 - Since 2002, the Roosevelt Island Tidal Energy (RITE) Project has been operated by Verdant Power in the East River of New York City. In three phases, the RITE Project seeks to develop, demonstrate and commercially deliver electricity generated from the tides of the East River using Verdant Power's Free Flow System. The Free Flow System is comprised of three-bladed, horizontal-axis turbines installed underwater to generate clean renewable energy from tidal, river and ocean currents. The project has received key support from the New York State Energy Research and Development Authority (NYSERDA), as well as the New York City Economic Development Corporation. more...

Basics of Geothermal Energy Production and Use

By Leslie Blodgett, Senior Editor, Geothermal Energy Association, April, 08, 2009 - Geothermal energy is defined as heat from the Earth. It is a clean, renewable resource that provides energy in the U.S. and around the world in a variety of applications and resources. Although areas with telltale signs like hot springs are more obvious and are often the first places geothermal resources are used, the heat of the earth is available everywhere, and we are learning to use it in a broader diversity of circumstances. The heat continuously flowing from the Earth's interior, which travels primarily by conduction, is estimated to be equivalent to 42 million megawatts (MW) of power, and is expected to remain so for billions of years to come, ensuring an inexhaustible supply of energy. more...
