I have never seen windpower get a favorable review whenever it is honestly analyzed. Add to that the slaughter of wildlife and there is no reason why windpower should even be considered. Wind farms kills more birds than all the oil spills of the world combined ever, in a single year.
I think wind power has been over-hyped, but it is still useful in countries like Spain and Denmark that have excellent wind conditions.
The bird thing always struck me as a bit of a red herring:
According to the CSE, for every bird killed by a turbine, 5,820, on average, are killed striking buildings, typically glass windows.
The CSE recommends building wind mills out of known migratory routes. That doesn't seem too hard.

I'll listen to these people a little more closely.....
The number of birds killed by wind turbines is highly variable. And biologists believe Altamont, which uses older turbine technology, may be the worst example. But that said, the carnage there likely represents only a fraction of the number of birds killed by windmills. Michael Fry of the American Bird Conservancy estimates that U.S. wind turbines kill between
75,000 and 275,000 birds per year. Yet the Justice Department is not bringing cases against wind companies.

ALTAMONT PASS, Calif. — The big turbines that stretch for miles along these rolling, grassy hills have churned out clean, renewable electricity for two decades in one of the nation's first big wind-power projects.

But for just as long, massive fiberglass blades on the more than 4,000 windmills have been chopping up tens of thousands of birds that fly into them, including golden eagles, red-tailed hawks, burrowing owls and other raptors.
After years of study but little progress reducing bird kills, environmentalists have sued to force turbine owners to take tough corrective measures. The companies, at risk of federal prosecution, say they see the need to protect birds. "Once we finally realized that this issue was really serious, that we had to solve it to move forward, we got religion," says George Hardie, president of G3 Energy.
