As by reported by Joby Warrick in the Washington Post, the first such study by the U.S. Department of Energy (DOE) in seven years predicts that easily a third of U.S. energy needs could be supplied by wind power by 2050.
The DOE report is entitled "Wind Vision: A New Era for Wind Power in the United States." The analysis estimates that wind power could support 600,000 jobs by mid-century.
