Can you identify when exactly the German environmentalists did this thing you refer to? I'm assuming it's something coal related.

Total and per capita coal usage for Germany and a few other peer nations:

I can see a bump in early 1980s but I see the same in other nations, possibly a response to oil embargoes, possibly just economic growth.
