The largest wind farm in North America, Alta Wind Energy Center in California, which is the third largest in the world, will be small in comparison with the proposed 3-GW Chokecherry-Sierra Madre Wind Project in the U.S. or the proposed expansion of China’s 6-GW Gansu wind farm to a staggering 20-GW by 2020.

Taking this change into account, it can be projected that approximately 681,000 birds are currently killed by wind turbines in the U.S. each year. These estimates likely underestimate the true extent of the problem due to the fact that many bird fatalities escape human detection. Photo by Anda Mikelsone/Shutterstock.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.The specific problem of bat deaths at wind turbines first came to biologists’ attention in 2003, when 2,000 bats turned up dead on a West Virginia wind farm.
