WSJ Opinion piece headline on production tax credit for wind power: "Puff, the Magic Drag on the Economy"

Lamar Alexander and Mike Pompeo: Puff, the Magic Drag on the Economy - WSJ.com

From 2009 to 2013, federal revenues lost to wind-power developers are estimated to be $14 billion—$6 billion from the production tax credit, plus $8 billion courtesy of an alternative-energy subsidy in the stimulus package—according to the Joint Committee on Taxation and the Treasury Department. If Congress were to extend the production tax credit, it would mean an additional $12 billion cost to taxpayers over the next 10 years.
...While the cost of renewable energy has declined over the years, it is still far more expensive than conventional sources. And even the administration's secretary of energy, Steven Chu, calls wind "a mature technology," which should mean it is sufficiently advanced to compete in a free market without government subsidies. If wind power cannot compete on its own after 20 years without costly special privileges, it never will.

Mr. Alexander is a Republican senator from Tennessee. Mr. Pompeo is a Republican congressman from Kansas.
