Many people think that building many different turbines will put the animals (mainly birds) at risk. While it is true that some birds do die in the windmills, the number is significantly lower than you might think.

The number of birds that die from wind power is much less than the amount of birds that die from car crashes, crashing into buildings, and even from being killed by housecats. In 2005 the birds that died from any one of those causes mentioned were in the millions. The amount of birds that died as a result of wind power only totaled 20 to 30 thousand.

While it is true that more birds are dying from wind power, it is also true that birds are more likely to die from many other things then a wind turbine. If buildings were to be built instead of wind turbines, the death rate of birds would likely be even greater.

Birds are not the only animals that could possibly fly into a wind turbine. Bats also crash into them once in awhile. This mainly occurs during migration because the bats may turn their sonar off and not see them coming. With their sonar off bats probably wouldn't see anything else either like trees, houses, etc.
