Germany's second largest coal company, Saarbergwerke, heavily dependent on public aid, is moving into wind energy. It is testing "all possible sites for wind" together with the Saarbruecken's college of technology and business studies, beginning with two coal waste tips: Goettelborn and Camphausen. Wind measurements are being carried out by Arge Solar, also of Saarbruecken. Saarbergwerke, together with the college and a local company, Leffer, is also developing its own wind turbine. The utility says: "In the construction and operation of both large and decentralised energy plant, Saarbergwerke is always at the forefront of energy technology developments."
