2012 proved to be a record-setting year for the US wind power industry. More than 13 gigawatts (GW) of wind power capacity was installed across the country last year, with a record-breaking 8,380 megawatts (MW) installed in the fourth quarter alone, according to the American Wind Energy Association’s (AWEA) 4Q industry report.
Leveraging private sector investment of $25 billion, utility-scale wind turbines were installed in 26 states and Puerto Rico in 2012.
Cumulative wind power generation capacity totaled 60,007 GW as of year-end 2012, with turbines up and producing clean, renewable electrical power in 39 states and Puerto Rico. The 60 GW milestone was breached just five months after AWEA announced cumulative US wind power capacity had reached 50 GW. The more than 60 GW rated capacity of installed US wind power generation is enough to supply the equivalent of nearly 15 million US homes – all those in Colorado, Iowa, Maryland, Michigan, Nevada, and Ohio combined — with electricity
