"Do you want the story of how I got rich and ran for governor? It's kind of a funny story." That's how former Maine Gov. Angus King, in a 2009 interview, described his entry into the world of energy conservation in the late 1980s -- a decision that would ultimately make him millions of dollars and pave the way for his successful 1994 gubernatorial bid. Since leaving office in 2003, King, who recently announced his independent bid for the Senate seat being vacated by Sen. Olympia Snowe (R-Maine), has returned to conservation, focusing on developing wind energy projects in his home state.
