Are just pulling this out of thin air or why are people spreading complete crap here? Just because Germany has such machinery it doesn't mean most of the electricity is from coal.
Here that's last year's energy mix in Germany: https://docs.google.com/viewer?url=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2F7%2F74%2FStrommix-D-2010.svg
Yes, that's 43% coal in total, but not the majority. It's a huge share, too huge if you ask me. But it won't increase significantly next years. The coal plants that are planned to be build until 2022 are mostly replacements for the old, aging and really dirty plants that are currently running. They were planned to be build either way, no matter if we shut down the nuclear power plants or not. So that share won't be affected.
What will be affected is the 22% nuclear energy share (it will drop to 0 by 2022) and the renewable energy share (currently around 17% if I calculated right) which is supposed to exceed 30% by 2022. Calculate in the saving by not exporting as much electricity and you'll see that there is no need to produce more electricity from coal.
Now put that into perspective with China (78% coal, 2% renewable energy) and the US (50% coal, 9% renewable energy) and then you'll see that you better think twice before telling anyone how to produce electricity.
