The US ranks second globally behind China with 91.42GW wind capacity, according to AWEA’s US Wind Industry Annual Market Report Year Ending 2013 released Thursday.

US developers installed 1.087GW of new capacity in 2013, the industry’s worst year since 396MW in 2004 and down 92% from 13.13GW in 2012.

“Most of us know the primary culprit behind the paradoxical market dynamics of the last couple of years - namely, the threatened expiration of the federal production tax credit (PTC), wind’s primary policy driver, and an extension that came too late to avoid damage to our industry,” AWEA says in the report’s introduction.
