Unfortunately, Germany has been ruled by a conservative party for the last 16 years and they did everything in their power to sabotage renewable energy so that lignite mining could stay longer. However, heating in Germany is a difficult problem to solve with renewable energy: You need lots of power in winter, when there is (close to) no power from solar. One solution would be excessive wind power and heat pumps that can be controlled remotely by the power grid operators.
