Actually, those studies have been blown way out of proportion. According to other studies, power lines, cars, pesticides, cats, tall buildings, and lighted towers all have a significantly larger impact on bird deaths than wind turbines. In fact there are statistics that show that of all bird deaths due to impact with man-made structures, wind turbines account for 0.01 - 0.02% (1 out of 5,000 to 10,000).
Newer wind turbines turn MUCH slower than the smaller-faster units. Not only do they last longer this way, but they also are much safer for birds and bats.
I truly believe this type of concern is a major reason that we have gotten into the mess we are in. I know animals need to be protected(whether it be in Alaska or the coastal area or the middle of the country), but when it causes such an economical problem for our country, what is more important? The fact, that we need fuels of all kind, to assist the people of this country. People need jobs, fuel to heat homes and gas for transportation to & from work. Also, fuel for the famers at a reasonable rate so food cost can come down. It is a shame when a country like the USA have people having to choose between food and medicines due to these high cost. I do know that many of the wealthy people do not believe that people in this country are starving, doing without medical care because of the economy.
