Wind installations in 2007 were not only the largest on record in the United States, but were more than twice the previous U.S. record, set in 2006. No country, in any single year, has added the volume of wind capacity that was added to the United States electrical grid in 2007. Federal tax incentives, state renewables portfolio standards (RPS), concern about global climate change, and continued uncertainty about the future costs and liabilities of natural gas and coal facilities helped spur this intensified growth. The yearly boom-and-bust cycle that characterized the U.S. wind market from 1999 through 2004-caused by periodic, shortterm extensions of the federal production tax credit (PTC)-has now been replaced by three consecutive years of sizable growth. With the PTC currently (as of early-May 2008) set to expire at the end of the year, 2008 is expected to be another year of sizable capacity additions. Unless the PTC is extended before mid-to-late 2008, however, a return to the boom-and-bust cycle can be expected in 2009.
