COTTBUS, GERMANY – APRIL 12: Exhaust plumes from cooling towers at the Jaenschwalde lignite coal-fired power station, which is owned by Vatenfall, April 12, 2007 at Jaenschwalde, Germany. Germany is planning the construction of 40 new coal-fired power plants, though officials claim the plants are based on technology that radically increases their efficiency. The Jaenschwalde power plant, built by the former East German government in the 1980s, emits 25 million tons of CO2 annually and is among the biggest single producers of CO2 emissions in Europe.
