Germany generated 45% of its energy from coal and 25% from renewable energy sources in 2013, according to AG Energiebilanzen. Chancellor Merkel, who as environment minister supported the Kyoto agreement in 1997, announced a plan to cut carbon dioxide emissions by an additional 62 to 78 million tons by 2020. The cuts will rest largely on improving energy efficiency, and with a third of the cuts in the power industry. With the drive to close 17 nuclear plants in Germany, the power industry has increasingly relied on coal generated energy. This is an effort to change this situation. It is supported by German public opinion.
