It's commonly believed that new wind power generation will displace coal and natural gas-fueled power plants and thereby avoid all their associated greenhouse gas (GHG) emissions such as carbon dioxide (CO2), nitrous oxide (NOX) and sulfur dioxide (SO2). The benefits of these avoided emissions have become a major factor in wind developers gaining public support for their plans to site wind farms. These purported benefits also are the reason for the large subsidies governments have provided to offset wind's higher power production costs. Unfortunately, some of these environmental claims are built upon incorrect assumptions about how U.S. environmental regulations actually work and the type of generation a new wind project will displace. On any given power project, the benefits of avoided air emissions can be calculated as the simple difference between whether a designated project is built versus if the project is not built. This simple calculation has been incorrectly done by several renewable project developers and their consultants. Their mistakes have led them to incorrectly claim large air emission benefits from building new wind facilities.

Eric R. Glitzenstein of the public interest law firm Meyer Glitzenstein & Crystal in Washington DC filed this letter with the U.S. Department of the Interior Secretary Kenneth Salazar on behalf of a number of conservation and citizen groups concerned with the impact of poorly sited and constructed wind power projects on bat and bird populations and other wildlife resources.

Wind advocates like to say "The wind's always blowing somewhere" to counter concerns about the variability of wind power. This is true, and it means that wind can always be relied on to produce some power, but that does not mean that wind can always meet demand. In the United States' Great Plains wind belt, wind is typically anticorrelated with demand.

This speech was delivered at the 22nd Annual Utah Valley University Symposium on Environmental Ethics, held April 1st and 2nd at Utah Valley University. Mr. Keith O. Rattie is the Chairman, President and CEO of Questar Corporation, one of America's fastest-growing natural gas producers.

Lisa Linowes, executive director of Windaction.org, presented these slides at the 2009 Midwest Energy Conference in Chicago (March 4-5). The focus of the presentation is on the costs and impacts of building an extensive transmission system to deliver wind and renewables from the central part of the United States to points east and west.

Wildlife expert Dan Boone presented these slides at the 38th North American Symposium on Bat Research held in Scranton, PA in October 2008. Mr. Boone's presentation focused on the trade-offs of wind energy development in Eastern US balancing the benefits of this energy resource against the environmental risks, particularly to bats. Note that slides # 27, 32 and 33 of the presentation provide graphs which quantitatively estimate the potential impacts on bats and forest habitat resulting from the projected intensity of wind energy development within the eastern US states which comprise the bulk of the Appalachian mountain region. The summary slide from the presentation is listed below. The full presentation can be accessed by clicking on the link at the bottom of this page.

Policy analyst and attorney, Drew Thornley, of the Texas Public Policy Foundation examines the growth of wind energy in Texas over the last decade. While many policymakers and business leaders foresee wind as a major contributor to America’s electricity supply, his report identifies several practical obstacles that stand in the way of achieving that vision.

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.

Texas oilman T. Boone Pickens is on a mission, and wants you to support his energy plan away from imported oil and towards natural gas and wind power. But commentator Will Wilkinson says to be wary of what you hear.
