This important report, which appeared in the Wildlife Society's Journal of Wildlife Management, details the effect on raptor and bird mortality following repowering a portion of the Altamont Pass Wind Resource Area (APWRA) in California (USA). Repowering involves removing older generation towers and replacing them with higher capacity -- and potentially better sited -- units. The abstract to this report appears below. The full report can be accessed by clicking on the link at the bottom of this page.

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 Animal Welfare Institute, Mountain Communities for Responsible Energy and David G. Cowan have filed a law suit against Beech Ridge Energy LLC and Invenergy Wind LLC under the federal Endangered Species Act ("ESA"). This filing seeks preliminary injunction to halt further construction, turbine erection, and operation of the Beech Ridge industrial wind power project. The plaintiffs argue that the project, if constructed, will result in the "likely killing, injury, and other forms of "take" of endangered Indiana bats in violation of the ESA." The wind project is proposed to be located on ridgelines in Greenbrier County, West Virginia.

Energy analyst Tom Hewson provides details on new wind power generation and whether the claimed benefit of avoided emissions is overstated.

Windaction.org is grateful to Dr. Smallwood for taking the time to develop these constructive comments in response to the US Fish and Wildlife Service's 3rd draft of its wind turbine siting guidelines.

In late February 2009 the Minnesota Department of Health (MDH) received a request from the Office of Energy Security (OES) in the Minnesota Department of Commerce, for a “white paper” evaluating possible health effects associated with low frequency vibrations and sound arising from large wind energy conversion systems (LWECS). MDH agreed to evaluate health impacts from wind turbine noise and low frequency vibrations. In discussion with OES, MDH also proposed to examine experiences and policies of other states and countries. Below are the Introduction and Conclusions of the white paper released in May 2009.

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.

Dr. Jay Apt presented this compelling testimony before the U.S. House of Representatives Subcommittee on Energy and Environment in reference to The American Clean Energy Security Act of 2009. Dr. Apt's full testimony can be accessed by clicking on the link(s) at the bottom of this page.

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.
