The booming U.S. wind market is set to cross the 150 gigawatt mark by 2020, according to a report from market research firm Emerging Energy Research (EER). That includes 5.33 GW installed last year, and another 8 GW currently under construction and planned for completion by the end of this year, EER says. But it will take actually double that 2020 projection — a total of 300 gigawatts — if we want to get 20 percent of our electricity from wind like the DOE and T. Boone Pickens think we can.
