From Robert Bryce at the National Review:
Proponents of wind-energy projects frequently claim that wind is free. That may be true, but creating jobs in the wind-energy business is a very expensive proposition.
The battle over the federal production tax credit (PTC) for wind, which amounts to 2.2 cents per kilowatt-hour and expires at the end of the year, is heating up. Last month, the Senate Finance Committee approved a plan to extend the PTC. Republican nominee Mitt Romney has said that, if elected, he will let the credit expire. President Obama wants to extend it: Last week, in a speech at the Democratic National Convention, he declared that “thousands of Americans have jobs today building wind turbines.”
