Wind power is poised to spread to entire US

New York

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

The bigger machines - reaching as high as 460 feet (140m) - 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.
