That's about all it took for a demolition crew to tear down seven wind turbines in Madison County, New York. As part of New York's first-ever commercial wind farm, the towering mechanical beasts came down not for any reason you'd expect. It had nothing to do with politics, health concerns, or aesthetics, or that birds might fear wind turbines. The Madison turbines were inefficient, and it was becoming too expensive for the local municipality to maintain them. New technologies offer more capabilities and some of the tech will even let wind turbines build themselves.
