BOXBERG, GERMANY – AUGUST 20: Steam rises from cooling towers at the Boxberg coal-fired power plant on August 20, 2010 at Boxberg, Germany. The Boxberg plant stands adjacent to Baerwalder See lake, which is actually a flooded, former open-pit lignite coal mine that once fed the Boxberg plant with coal. The lake is part of a large-scale project to convert the massive pits that scar the region into a vacationer’s paradise. The Lausitz and Middle German Mining and Administration Association (LMBV) is converting a total of 51 former mines, of which Baerwalder See is among the biggest, into lakes, and a similar project is planned for former mines in neighboring Poland.
