FELDHEIM, GERMANY - JUNE 20: Michael Knape, mayor of Treuenbrietzen, which also includes the village of Feldheim, poses for a portrait in a field of barley on June 20, 2011 in Feldheim, Germany. Feldheim recently won recognition from the state of Brandenburg for becoming exclusively reliant on alternative energy sources for its energy needs. It produces electricity and heat at a biogas facility and also draws electricity from nearby wind and solar farms operated by renewable energy supplier Energiequelle GmbH.
