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: https://ourworldindata.org/grapher/coal-consumption-by-country-terawatt-hours-twh?tab=line&country=JPN~DEU~USA~GBR https://ourworldindata.org/grapher/coal-consumption-by-count... https://ourworldindata.org/grapher/coal-consumption-per-capita?tab=line&country=USA~GBR~DEU~JPN https://ourworldindata.org/grapher/coal-consumption-per-capi... 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.
