Yes, bird and bat deaths from wind is hard to take. But, the Wind industry has a higher standard than "Cat Owners" and some other contributors. New technology, painting turbine wings, echo chamber tech. for the bats, base cultivation, and the list goes on come from a Green Wind Industry with higher standards than others. Bird fatalities have been dramatically cut while bat fatalities have been cut in half.
A Greater Perspective
If we’re looking at the bigger picture, wind power’s impact on bird populations is relatively small when compared with other human-related sources of avian mortality. Numerous studies demonstrate that far more bird deaths are caused by collisions with buildings (676 million), vehicles (214 million), and power lines (32 million) in the United States. (It should be taken into consideration, though, that birds killed by wind turbines have historically been of higher conservation value than the robins and sparrows killed by non-wind-related sources.)
