...some wind power facilities, such as the Altamont Pass Wind Resource Area (APWRA) in eastern Alameda and Contra Costa Counties, California, are causing severe environmental impacts to raptor populations due to bird kills from collisions with turbines and electrocution on power lines.
This letter from the West Virginia Field Office of the US Fish and Wildlife Service to NedPower Mount Storm responds to the developer's biological assessment for endangered bats at the proposed Mount Storm Windpower project site to be located in Grant County, West Virginia.
There is less than 4% of native tallgrass prairie left in North America, and two-thirds of it is right here. Once you have experienced the spaciousness and exceptional beauty of open native grasslands, you know there is nothing in the world quite like it. These native grasslands are truly a national as well as a Kansas treasure.
Wind turbines in the Altamont Pass Wind Resource Area (APWRA) provide on average 1.1 billion kilowatt-hours (kWh) of emissions-free electricity annually, enough to power almost 200,000 average households per annum, but these turbines also kill birds that are legally protected, and have been doing so for decades. This five-year research effort focused on better understanding the causes of bird mortality at the world's largest wind farm. Researchers studied 2,548 wind turbines and combined their data with results from 1,526 wind turbines they had studied previously. They sought to: (1) quantify bird use, including characterizing and quantifying perching and flying behaviors of individual birds around wind turbines; (2) evaluate flight behaviors and the environmental and topographic conditions associated with them; (3) identify possible relationships between bird mortality and bird behaviors, wind tower design and operations, landscape attributes, and prey availability; and (4) develop predictive, empirical models that identify turbine or environmental conditions that are associated with high vulnerability. Researchers concluded that bird fatalities at the APWRA result from various attributes of wind turbine configuration and placement, and that species-specific behavior plays a large role in how each contributory factor affects mortality. The report details numerous specific observations. Researchers identified and evaluated possible measures to mitigate bird mortality in the APWRA. They offer recommendations to discontinue or modify some current management actions, to implement new ones immediately, and to experiment with others. Data presented in the report support these recommendations. The results suggest that repowering with carefully placed, modern wind turbines mounted on taller towers may be the preferable means to substantially reduce bird mortality.
Researched and written by Eleanor Tillinghast of Green Berkshires Inc. this is a comprehensive study of the probable impact of industrial wind plants on the rural character, quality-of-life and economy of the Berkshires in western Massachusetts. Specific issues addressed include visual aesthetics, tourism, property values, public roads and public safety.
Although my research started with the visual and spatial aspects of WECSs, and continues to be focused on WECSs effects on “landscape character” i.e. impacts on the spatial environment, with implications for cultural values and social systems of our region. I am equally concerned about the predictable negative effects of WECSs on the natural systems of the Flint Hills. I am concerned about serious cumulative effects and the degradation of: the visual character of our environment; the social fabric of communities that are facing the prospect of WECS-C; the health of biological, ecological components of our regional ecosystem; and the long term viability of our local, increasingly “nature-based” economy.
This document [DEIS] has not provided any demonstrable public need for the insignificant amount of power this facility is capable of producing. No valid, compelling local (or even statewide) economic reasons were offered to potentially offset the overwhelming negative impacts that will result if built. This DEIS is abundant in quantity, but extremely lacking in quality of scientific analysis and entirely deficient in analysis in certain areas. Various mitigations offered are unacceptable or unworkable. The following are areas of analysis that were either deficient or not performed at all:............
Wind turbines to produce electricity on a large scale – “wind farms” – are currently being proposed for parts of Tug Hill. Large-scale wind farms are a relatively new occurrence in the Northeast, and since they are new there are many questions that do not have clear answers.

New Jersey Audubon Society (NJAS) and its 20,000 members generally support environmentally-responsible renewable energy sources, such as wind power, photovoltaic cells, geothermal and hydro-fuel cells. Because traditional energy sources contribute to global climate change, habitat change and degradation, smog pollution, mercury contamination in our waterways, and radioactive waste, NJAS recognizes the importance of developing emission-free sources of energy. However, we are concerned about the potential impacts of these developing technologies on wildlife, and natural habitats.
More than 25 national and regional conservation groups, including Defenders of Wildlife, National Audubon Society, the Humane Society of the United States, and the Endangered Species Coalition, today called on Interior Secretary Gale Norton and other federal officials to assess the impacts of planned extensive wind power development on Appalachian mountain ridges on migratory birds, before these projects are constructed. In a letter to Secretary Norton and others, the groups cited documented bird kills by existing wind turbines in the region, and urged the U.S. Fish and Wildlife Service (FWS) to develop appropriate criteria for siting and construction of these facilities under the Migratory Bird Treaty Act, which makes it illegal to kill migratory birds.
The attached pdf file contains a letter written by Steve Anschutz, Nebraska Field Supervisor of the USF&WS, to Rockford Plettner, Environmental Specialist Water/Natural Resources of Nebraska Public Power District (NPPD). The letter responds to a NPPD request for input regarding the possible construction of a wind farm south of Ainsworth, Brown County, Nebraska. The letter's comments are provided as technical assistance and predevelopment consultation....

The commission unanimously voted down the proposal after a five-hour hearing attended by more than 150 people at Santa Clarita City Hall. Zond Systems, the largest producer of wind energy in California, had hoped to erect more than 300 windmills--some as tall as 150 feet--on vacant, mountainous land near Gorman.
The proposed Deerfield Wind project in Readsboro and Searsburg is continuing to move forward with the Public Service Board approving a plan for a bear study and the public comment period set by the Green Mountain National Forest ended.
