The Obama Administration is calling for continued government support of wind energy, touting a new report showing that it accounted for nearly a third of new electric capacity added in the United States last year. A report released Tuesday by the Department of Energy says the U.S.wind power industry is “facing uncertain times,” growing strongly but confronting the possibility of an expiring tax credit that would deal it a severe blow. Roughly $14 billion was invested last year in the industry, which accounted for 32% of new U.S. generating capacity, the report says. The U.S. has also become a major player on the manufacturing side, producing 67% of new wind turbine equipment used domestically last year.
