This presentation by Germany's Working Group on Renewable Energy summarizes the development and status of renewable energy sources in Germany in 2010. Topics include the contribution of renewable energy sources to energy and electricity supply, associated avoidance of carbon dioxide (CO2) and greenhouse gas emissions, and share of renewable energy sources in total final energy consumption in Germany. The presentation also highlights the historical growth of individual renewable energy technologies (e.g., wind, solar, biomass, geothermal heat pumps).
