The American Wind Energy Association said new wind turbines this year will generate about 7,500 megawatts of additional electricity, far surpassing the 5,249 megawatts installed in 2007.
Wind power accounted for more than one-third of the new electric generating capacity installed in the U.S. in 2007, and the industry is projected to grow at a 45 percent pace for the second straight year, said Randall Swisher, the association's executive director.
"We're past the point of wind being a marginal player," Swisher said.
A financial bailout package passed by Congress and signed by President Bush provided an eight-year extension of investment tax credits for the solar industry but gave just a one-year extension of production tax credits for the wind industry.
Swisher said capital in the near term clearly will cost more and be more difficult to get, but other factors provide a bit of a silver lining. Transportation costs are continuing to come down, and steel prices have dropped significantly in the past few months. A wind turbine, by weight, is 89 percent steel, Swisher said.
Industry growth is also occurring on the manufacturing side.
Eight new wind turbine component manufacturing facilities opened in the U.S. this year, nine were expanded and 19 new facilities were announced, according to the trade group.
Swisher said governors from states such as Colorado and Iowa have worked hard to attract companies that build turbines, towers and blades to fuel their local economies.
"Wind will be one of the leading sources of new manufacturing jobs in the 21st century," he said. "And there are a bunch of governors that are starting to figure that out and are driving their own state economic development strategies to take advantage of that."
