Synthesis of operational mitigation studies to reduce bat fatalities at wind energy facilities in North America
We conclude that increasing cut-in speed between 1.5 and 3.0 m/s or feathering blades and slowing rotor speed up to the turbine manufacturer’s cut-in speed yields substantial reductions in fatality of bats. Given the magnitude and extent of bat fatalities worldwide, the conservation implications of our findings are critically important. Research efforts should continue to focus on incorporating additional variables, in addition to wind speed (e.g., temperature, time of night, bat activity) into treatments and explore using automated systems to . . .

Ecological impacts of wind energy development on bats
Thomas Kunz, of the Center for Ecology and Conservation Biology, Boston University, with colleagues from Bat Conservation International, Western EcoSystems Technology, the U.S. Fish and Wildlife Service, the Illinois Natural History Survey, and the National Renewable Energy Laboratory, reviews the state of knowledge about impacts of wind energy facilities on bats. Published in Frontiers in Ecology and the Environment, August 2007. Of particular concern is the cumulative effect of continuing wind energy development. Based on existing studies and the proposal . . . Complete article »
