Wildlife and Wind Energy
Birds and bats are occasionally killed in collisions with wind turbines. Like any form of development, wind projects can also negatively impact wildlife by altering habitat. However, although the wind industry receives a lot of attention for avian impacts, research shows that nuclear and fossil-fueled plants have a greater impact. The Avian and Wildlife Costs of Fossil Fuels and Nuclear Power report, for example, quantifies those impacts. The study estimates that wind farms are responsible for roughly 0.27 avian fatalities per gigawatt-hour (GWh) of electricity while nuclear power plants involve 0.6 fatalities per GWh and fossil-fueled power stations are responsible for about 9.4 fatalities per GWh. Within the uncertainties of the data used, the estimate means that wind farm-related avian fatalities equated to approximately 46,000 birds in the United States in 2009, but nuclear power plants killed about 460,000 and fossil-fueled power plants 24 million. 
Over the past two decades, wind development's impact on birds has been greatly reduced by improvements in turbine design and particularly through improved project and turbine siting. Organizations such as the National Wind Coordinating Collaborative and the Bats and Wind Energy Cooperative are working to reduce the risks of wind development to wildlife by participating in collaborative research and outreach efforts with industry. The wind industry, in partnership with environmental organizations, is also taking action to reduce wildlife impacts through the efforts of the American Wind Wildlife Institute.

The American Wind Wildlife Institute (AWWI) facilitates responsible development of wind energy while protecting wildlife and wildlife habitat. AWWI was created and is sustained by a unique collaboration of environmentalists, conservationists, state wildlife agencies, and wind industry leaders. Its purpose is to help lay the scientific groundwork and best practices for wind farm siting and operations through targeted initiatives: wind-wildlife research, landscape assessment, mitigation, and education. The AWWI offers the Landscape Assessment Tool, a general screening tool using data available to the public to provide current information about the environmental characteristics and important landscape-level wildlife values of a geographic area.
