Goal of 80% Renewables by 2050Germany has been a rock star lately when it comes to clean energy. Their policies have encouraged huge growth in solar and wind, and over the years this has added up to a very significant chunk of the country's total energy use. The Bundesverband der Energie- und Wasserwirtschaft (a utilities association) said that the "share of wind, solar and biomass power is expected to rise from 20 percent in 2011 to 23 percent this year." That's a 15% increase, which is impressive on such a large installed base (we're not talking about 1-2% of total like in some countries).
The Washington Post reports that "strong growth in new solar power installations — helped by subsidies — is expected to lead to a solar output surge of 47 percent to 28.5 billion kilowatt hours," and that renewable sources should provide 40% of the country's energy by 2022 and 80% by 2050.
