Wind Turbine Mortality

As the Obama administration pushes for clean energy one possible source would be wind farms with dozens or even hundreds of wind turbines. These might be thought to be environmentally friendly, although they're aesthetic eyesores, since they don't have any perceptible impact on the land and don't generate any pollution. They do have an important downside, though, as this article from the American Bird Conservancy explains:

Recent U.S. studies indicate that bird mortality at wind turbine projects varies from less than one bird/turbine/year to as high as 7.5 birds/per turbine/year. This means that between 10,000 and 40,000 birds may be killed each year at wind farms across the country - about 80% of which are songbirds, and 10% may be birds of prey. While not a large figure, local or regional impacts may be significant, and the rate of increase in turbine construction has conservationists concerned that new generators be built to standards that minimize the potential for bird kills. Bats are also subject to high mortality at wind farms frequently at considerably higher rates than birds.

The increasing number of proposals for new projects has stimulated discussion on the need for proper siting, operation, and monitoring guidelines or regulations to prevent, or at least keep to a minimum, avian and bat mortality.

Before construction of new wind farms, detailed studies should be conducted to assess the potential impact on birds, bats, and other wildlife. Sites known to be used by birds and bats listed under the Endangered Species Act should be avoided if the construction and operation of wind plants might adversely affect these species, as should locating turbines in known local bird migration pathways, in areas where birds are highly concentrated, or in areas or landscape features known to attract large numbers of raptors.

So I wonder if the following isn't a plausible scenario. President Obama gets cap and trade and wipes out the coal industry as he admitted his policy would do (see here). Entrepreneuers then try to get into the wind farm business, but they find that because of the effect of turbines on wildlife few of their siting proposals can pass EPA muster. So now we have no coal generated electricity and no wind generated electricity. Then what? Relax EPA standards? Build nuclear plants? Fat chance of that as long as the Democrats control the approval process.

What's most likely, it seems to me, is that electricity will get rationed just like medical care. You'll only be able to use it during certain hours of the day and in certain amounts. Kiss that air-conditioner good-bye, hope and change are cool enough all by themselves.
