Obama presses Congress to extend energy tax incentives

The American Wind Energy Association, a trade group, warned in April that with the expiration looming, “the supply chain is feeling the uncertainty, and layoffs have now begun.”

While wind power has bipartisan support — Midwest and Great Plains Republicans are particular fans — extension of the credit this year is uncertain amid election-season political battles over green energy and other factors.

Separately, the 2009 stimulus provided $2.3 billion worth of credits for manufacturing equipment such as solar panel components, “smart” electric meters, fuel cell components and wind turbines.

Applications for the 30 percent credit far outstripped the $2.3 billion cap, but several congressional efforts to add billions of dollars to the cap have sputtered.
