Evolving Trends in Wind Power Generation

By Harry Valentine, Commentator/Energy Researcher, , December, 15, 2009 - Wind power generation is expanding worldwide with the tower-mounted 3-bladed design being the most popular wind power conversion technology. However, the variation of designs and range of output level is expanding as researchers and developers continually seek innovative ways to reduce the cost per kilowatt. Small-scale designs that cover the range of 200-watts to 5-kw is the fastest growing segment of the wind power market. Much of the technology in this power range can be mass-produced, including the bladeless solid-state piezoelectric device where wind-induced vibration produces electric power.  more...

Offshore wind: Comprehensive initial study is critical

By Matthew Pollard, P.E., Project Engineer, Fugro West, Inc., November, 17, 2009 - Utilities have begun considering offshore wind as a source of new energy. Delmarva Power recently agreed to a long-term offshore wind power purchase contract, and organizations such as Long Island Power Authority and Public Service Enterprise Group are exploring the development and operation of offshore wind farms. The energy industry often focuses on the real-time data and operating challenges of wind, but it is also important to consider the upfront data and information challenges of planning wind resources -- particularly offshore wind.  more...

Offshore Wind Could Surge

By Ken Silverstein, Editor-in-Chief, EnergyBiz Insider, October, 20, 2009 - Offshore wind production could surge forward. Both European and U.S. advocates say that the construction of such energy projects could take off assuming that both continents stick with their carbon-free energy themes. Offshore wind development, in theory, would avoid the typical in-fighting that occurs with respect to all other of power projects that are built on land. In practice, however, it is just as onerous largely because the wind mills in some places could be seen by local residents and because of the extensive underwater transmission systems that are thought to harm sea life.  more...

Wind Turbine Supply Chain Strategies: 2009-2020

By Keith Hays, Research Director, Emerging Energy Research, September, 15, 2009 - The global wind turbine supply chain faces the challenging task of bridging the gap between the high level of growth and the bottlenecks of 2008, and the resumption of high growth expected in 2010. Although some capacity investments have been frozen and new market entries postponed, 2009 has offered the industry a breather to retool its strategy for longer-term, sustained growth as demand becomes more consolidated globally. The global wind turbine component supply market will be shaped by the following key trends in the near term as the industry looks forward to the next economic cycle, including:  more...

The Role of Wind Forecasting in the Successful Integration and Management of an Intermittent Energy Source

By Dr. Jeff Lerner, Director of Product Delivery, 3TIER, July, 28, 2009 - Owing to the increased penetration of wind power, utility and system operators familiar with managing non-renewable power sources are being forced to learn new a new trade: wind forecasting. When the relied-upon fuel is inherently intermittent -- not a characteristic of traditional energy sources -- understanding the supply side of load balancing, dispatchability and reserves, and the cost of producing electricity inevitably becomes more challenging. This paper discusses how and why accurate wind forecasting is a necessary ingredient for the continued growth and penetration of wind power into the global energy mix. It is equally important to note the critical need for proper collaboration in planning the distribution and size of wind projects, and the electricity transmission grid from the municipal to international scale. Such efforts would require significant cooperation by parties spanning from industry, policy, education and research.  more...

Wind, Backup Power and Emissions

By Michael Goggin, Electric Industry Analyst, American Wind Energy Association, June, 23, 2009 - More than 8,300 MW of wind plants were installed last year, comprising about 42 percent of all new electric capacity added in 2008. Nevertheless, myths continue to persist about wind, including that wind does not reduce fossil fuel use and associated emissions and, related to that, myths about the need for "backup power" from fossil fuel power plants. In reality, each megawatt-hour (MWh) produced by a wind plant replaces a MWh that would have been produced by another power plant.  more...

Winds of the Kiowas

By Fred Kesinger, CEO, Everest Consulting Partners, May, 26, 2009 - For many years the Kiowa Indians freely roamed throughout the panhandle of Texas up through the panhandle of Oklahoma and on into south central Kansas. The tall grass prairie was good to them. It fed their horses. The buffalo numbered in the tens of thousands and provided food, leather for clothes and blankets for wintertime. The water was pure and they drank freely without fear of giardia or any other contamination. The sun shone brightly as there was no manmade air pollution. Only an occasional tornado. The wind blew continually -- sometimes from the southerly direction -- and in the winter it blew reliably from a northerly direction. Life was good and the Kiowa's flourished for many years.  more...

Who Owns the Wind? An Emerging Public Policy Issue

By Ron Rebenitsch, PE, MBA, , April, 28, 2009 - Part II of this article will explore the pros and cons of the regulatory and unitization models.
 
First in Time; First in Right
 
This regulatory model approach is essentially what the title implies. In typical western water law, the first user to develop a qualified use of water (i.e., irrigation) from a flowing stream develops certain rights to divert a defined quantity of water from the stream if it is available. That diversion quantity is allocated or "adjudicated" to this user according to applicable state laws.  more...

Who Owns the Wind? An Emerging Public Policy Issue

By Ron Rebenitsch, PE, MBA, , March, 24, 2009 -

As wind energy continues its major expansion in the U.S., the allocation and definition of property rights related to wind could rival the historical "water wars" of the West. Defining the legal boundaries of wind rights and how they will be allocated is emerging as a major policy issue for state legislatures and regulators.  more...
