All 50 states could become wind energy producers, according to an Energy Department report released Tuesday, once the next generation of larger, taller turbines in development hits the market.

The bigger machines — reaching as high as 460 feet — could eventually make faster winds at higher altitudes an economical source of electricity, an important part of reaching the nation’s goals in fighting global warming, said Ernest Moniz, the secretary of energy.

“We believe very much the central role of wind in meeting our climate challenges, and we’re very committed in this direction,” Mr. Moniz told reporters after speaking in Orlando, Fla., at the annual conference of the American Wind Energy Association, the industry’s main trade group.

“It’s going to require being able to take advantage of a broader set of resources,” he said, and it will give wind power a “bigger footprint,” onshore and off.
