According to the American Wind Energy Association, the U.S. now has 9,149 MW of wind capacity installed after a record 2,431 MW of new installations in 2005. And since the federal production tax credit will remain in place until at least the end of 2007, AWEA is expecting rapid growth to continue for at least two more years.
