Isi artikelA freight train, its dozen cars loaded with coal covered in a light dusting of snow, snaked through the narrow valley, sometimes following the two-lane highway and sometimes crossing it. The valley was silent and snowy, and though it was two days into 2012 it could easily have been 1982, 1942 or 1922: coal has been mined in Appalachia and carried out by rail for well over a century. And by some measures, coal is still going strong. It provides more of America's electricity than any other fuel. The Energy Information Administration (EIA) reckons America has enough coal to meet current demand levels for the next 200 years. But if the raw numbers look good, the trends tell a different story. Regulatory uncertainty and the emergence of alternative fuel sources (natural gas and renewables) will probably make America's future far less coal-reliant than its past. Toughening regulation has an effect, too. Coal-fired power plants are the source of more than one-third of greenhouse-gas emissions in America.
