A small town in Missouri has switched to wind energy, producing enough to dump its surplus onto the local grid.  Pretty cool.  More at http://www.rockportwind.com/

From the town's press release:

Rock Port’s 100% wind power status is due to four wind turbines located on agricultural lands within the city limits of Rock Port. The city of Rock Port uses approximately 13 million kilowatt hours of electricity each year. It is predicted that these four turbines will produce 16 million kilowatt hours each year. Excess wind generated electricity not used by Rock Port homes and businesses will move onto the transmission lines to be purchased by the Missouri Joint Municipal Utilities for use in other areas. This makes Rock Port, Missouri the first community in America capable of meeting its entire annual electricity demands from wind power!
