Reader Joseph Willemssen, in the comments to the recent post on Renewables Across the Country, linked to the American Wind Energy Association database of projects. The map showing the amount of wind power by state immediately draws the eye: California tops the list with 2,114 megawatts; Texas is a distant second at 1,288 (but since the database was last updated in late July, that won't include Sweetwater 2, so that should be 1,379 megawatts); Minnesota comes in third, with 595 megawatts. 15 states have no wind generation at all.
Total installed wind generation in the US: 6,831 megawatts (including Sweetwater 2). An impressive total, to be sure, but we still have a long way to go.
(Thanks, Joseph!)
