Well a quick search turns up about 29.3% coal, that's a lot compared to specifically France (1.8%). That's because France is crazy into nuclear (71.6%) which the green movement made wildly unpopular in Germany (13.7%). To add one more comparison point, US is 23.5% coal and 19.7% nuclear. Natural gas is 10.5% in Germany, 7.7% in France, and 38.4% in the US.
