A study by the National Academy of Sciences found that wind energy could reduce the energy sector's carbon dioxide emissions by 4.5 percent by 2020, Wind power also reduces global-warming pollution, so fossil fuel emissions will kill much more birds because of environmental impact.
Wind farms are able to generate 7 percent of U.S. electricity in 15 years, also wind energy costs cheaper than fossil fuel.
So it has less environmental impact than other kinds of energies, but at the same time it can be bad for birds. According to statistics wind turbines kill less birds than aoutos and building, but it can threaten whole flocks of birds especially in migration corridors. It is very important to be extremely careful while locating and regulating turbines.
"The first three rules of avoiding impacts with wind turbines are always going to be location, location, location," Mike Daulton, a spokesman with the National Audubon Society, said in a telephone interview.
A wind farm went up at the Altamont Pass Wind Resource Area in California in the 1980s that has killed birds of prey like golden eagles, whose populations are still recovering from use of the now-banned pesticide DDT.
A wind farm in California Altamont Pass Wind Resource Area killed a population of golden eagles in the 1980s. The population is still recovering from that huge harm.
Texas is the home of tanagers, that can suffer from turbines. "I don't envision these wind turbines being like a giant weed eater chopping birds to bits," said Clifford Shackelford, an ornithologist at the Texas Parks and Wildlife Department. But the same tanager can suffer not only from turbines, but also from bad weather. And when the weather is very bad to the birds, the lights of the turbines help them find the right way to fly.
North and South Dakota are the home of water fowl populations, which can also appear at risk because of wind power.
Wind farms have 197 and 295 feet tall towers with blades that have diameters ranging from 230 to 295 feet. Most of the farms have hundreds and sometimes even thousands of that kind of towers., which can kill entire bird populations of migrating birds.
