ADVANCE FOR MONDAY, DEC. 19 AND THEREAFTER - In this photo taken Wednesday, Dec. 14, 2011, the stacks of Dominion's power plant tower over a nearby neighborhood in Salem, Mass. More than 32 mostly coal-fired power plants in a dozen states will be forced to shut down and another 34 might have to close because of new federal air pollution regulations, according to an Associated Press survey. Together, those plants produce enough electricity for more than 21 million households, but their demise is unlikely to cause homes to go dark. (AP Photo/Charles Krupa)
