The American Electric Power Company's cooling tower at their coal-burning Mountaineer plant is shown in this file photo taken October 27, 2009 in New Haven, West Virginia. The Obama administration proposed March 27, 2012 the first ever standards to cut carbon dioxide emissions from new power plants, a move likely to be hotly contested by Republicans and industry in an election year. The Environmental Protection Agency proposed the long-delayed rules that limit emissions from all new U.S. power stations, which would effectively bar the building of any new coal plants.
