Wind turbines are pictured in this multiple exposure at the German village of Feldheim February 21, 2013. Feldheim, a 60-minute drive south of Berlin and home to about 125 people, is Germany's first and only energy self-sufficient village. Germany is a world leader in renewable energy and derives a quarter of its electricity from renewables, but rising prices have turned into a major political issue ahead of the election.
