NREL has started to analyze the wind climatology at advanced turbine hub heights based on data measured on existing tall towers in Kansas, Indiana, and Minnesota. The highest measurement level at these towers was 90–110 m. There are two significant findings from the analysis: (1) the difference in wind resource at tall tower sites in the central United States seems to be controlled by the strength of the noctural and southerly winds; and (2) the average wind shear exponent of 50-100 m at tall towers in the central United States is influenced by strong southerly winds and is significantly higher than the 0.143 often used for conservative estimates of the wind resource at turbine hub height.
Glenn Schleede examines the financial incentives available to owners of industrial wind energy and how taxpayers and utility customers are picking up the tab.
The U.S. wind industry experienced a banner year in 2008, surpassing even optimistic growth projections from years past. At the same time, the past year has been one of upheaval, with the global financial crisis impacting near-term growth prospects for the wind industry, and with significant federal policy changes enacted to push the industry towards continued aggressive expansion. Dr. Ryan Wiser, and others, prepared this detail analysis of wind development in the United States.
The annual wind market report is an important document for those tracking trends in the U.S. wind industry. The report provides information on wind energy's performance and cost in key regions of the country and explains economic and social forces impacting industry growth.
Economist Dr. Robert Michaels explains the flaws with NREL's JEDI modeling when evaluating the job creation and economic impacts of building renewable energy facilities.
Impatience to solve current problems has resulted in aggressive RPSs with strict deadlines. Although we agree that renewable technologies will help attain social goals, mandating rapid, massive deployment of these technologies will result in high cost, disputes over land use, and unreliable electricity, leading to a public backlash against these policies. The United States needs to focus on the goals, provide substantial incentives to meet them, and avoid polices that exclude economical ways to meet them.
The informative paper provides a clear explanation of the risks and harm of relying on 20% of our electricity supply from intermittent renewable energy. The author is President and CEO, Deseret Power, an electric cooperative located in Utah. The concluding section of his paper appears below.

Renewable energy—harnessing the power of the wind and the sun—sounds wonderful until confronted with the facts. While wind and sun are indeed free, turning their energy into consumer-accessible electricity is not. Nor is it easy. Wind power must be used at the moment the wind is blowing— which it generally does not do during blazing-hot summer days, the peak of electricity use. Both solar and wind power require costly installations and transmission mechanisms. Instead of saving money for Americans, renewable energy sources are much more likely to spike their utility bills. Nevertheless, Congress is considering a mandate for a nationwide renewable electricity standard (RES). Heritage Foundation energy policy experts explain why an imposed national RES would be bad for families, bad for business, and bad for the economy.
During a recent roundtable discussion concerning wind power projects at the Delaware County Historical Society a participant affiliated with two local wind development companies stated that there were three issues where the health and safety impacts were predictable and avoidable---- ice throws, noise, and flicker. Since the statement was made in the presence of planners who are advising towns in the process of writing regulations to protect the health and safety of residents, I felt that a fuller discussion of the known science of these issues was important, and have prepared this report to that end.
