Not sure I follow, even if coal were used for heating in Germany. Would the country be in a better environmental situation overall without the activists? I don’t doubt there’s some level of energy hypocrisy currently going on in Europe, but I don’t see how environmentalists have exacerbated the current crisis. Are you referring to their opposition to nuclear energy?
Yea because if it weren't for these people, Germany would have invested in Nuclear or secure better natural gas than from Russia (Algeria?). Nord Stream 1 was hastily negotiated with the devil. Devil then invaded Crimea to secure the oil fields. Then 8 years later, they did it again with Nord Stream 2! The devil used it as a leverage to take big chunks of Ukraine. Trump warned them (as much as I loathe the guy, he was right, unsophisticatedly but eerily accurate): https://www.youtube.com/watch?v=O24rulfjA8U
Environmentalists also invested in Solar energy in Germany. It has to be the dumbest idea ever, solar power in Germany is like 10% as efficient as Western USA. It is one of the worst places in Europe to stick solar panels. https://en.wikipedia.org/wiki/Solar_power_in_Germany
In general, Environmentalists do not understand the difference between gardening and farming. It's the Greta crowd that's going to lead this world towards mass starvation of humans. They have no solutions, only blind clueless activism.

Tried, but then they got back-up in the form of European and US weapon shipments that are trouncing the Russian's poorly trained forces and equipment - or, that's what the diverse media in my neck of the wood is saying. Russia doesn't seem to be winning or gaining though.
