Midwest Generation's Fisk Generating Station, a coal-fired power plant, is seen Wednesday, Feb. 29, 2012, in Chicago. The city's two coal-fired plants will shut down early under a deal between the operator, city officials and environmental groups. The Chicago Clean Power Coalition says Midwest Generation signed an agreement Wednesday to close its Fisk plant by the end of the year and its Crawford plant by the end of 2014. Chicago is the only large U.S. city with coal-fired power plants operating within its borders. (AP Photo/M. Spencer Green) less
