Is the sun setting on wind power growth? This fast-moving electricity source could slow if Congress doesn’t pass a new renewable production tax credit.

On a percentage basis, wind power is the fastest growing electricity source in the United States. This didn’t happen in a vacuum. The federal renewable production tax credit has promoted the development of wind and other renewable energy. But this simple, effective idea — invest in renewable energy and Uncle Sam gives you a credit on your tax bill — could be history unless the Senate acts soon.

Second largest source of new power production added in 2007:
Wind power at 30%

Years with continuity in production tax credit:
2005 through present

Years renewable production tax credit was allowed to expire:
2000, 2002, 2004

Average drop in added wind capacity in years after tax credit expired compared to previous year:

Next expiration date of current production tax credit:
December 31, 2008

Number of months the current Congress has been in session:
20 ½

Number of months it took Congress to enact a new renewable production tax credit:
Has yet to happen

Number of months left before renewable production tax credit expires:
Less than 4
