HAMM, GERMANY - MAY 23: Power lines lead away from the Kraftwerk Westfallen coal-burning power plant on May 23, 2011 in Hamm, Germany. The plant, operated by German utilities giant RWE Power AG, was originally built in the 1970s, though two new additions under construction as part of a modernization effort will increase the plant's output by 1,600 Megawatts for a total capacity of 1,884 Megawatts. The future of Germany's energy supply is currently a hot topic of political controversy. The government has pledged to hasten the country's withdrawal from nuclear energy and pledged support for renewable energy sources, including solar parks, wind turbine farms and biomass projects, yet burning coal is and will remain the main means of electricity production for at least many decades to come.
