The wind industry became a leading power provider in the United States during 2012. According to the American Wind Energy Association (AWEA), nine states received more than 10 percent of energy from wind power.
The organization said wind energy generation in the United States grew 17 percent last year, accounting for 3.5 percent of all energy produced during 2012.
"With wind power serving as the number one source of new generating capacity in 2012, it's no surprise that wind energy is increasing its role in the overall U.S. power mix," said Elizabeth Salerno, director of industry data & analysis at AWEA.
Iowa and South Dakota had the two largest amounts of wind power generation in 2012, with wind energy accounting for more than 23 percent of the states' total electricity generation during the year. AWEA said wind energy represented at least 5 percent of electricity generation in 14 other states.
During all of 2012, the United States installed 13,124 megawatts of wind energy and achieved more than 60,000 MW of cumulative wind capacity. AWEA said wind power provided almost 42 percent of new energy generating capacity in the United States in 2012.
"We are generating enough clean, affordable, American wind energy to power the equivalent of almost 15 million homes, or the number in Colorado, Iowa, Maryland, Michigan, Nevada, and Ohio combined," Salerno said.
