Basically, the entire European green and anti-global warming movement was either delusional or bought off and there was (and still is) not really much of a counterbalance to this within the mainstream. They pushed for renewables that required a huge amount of natural gas as backup for when the wind dropped or the sun went behind clouds and for the shutdown of alternatives like coal and nuclear, whilst simultaneously campaigning to block new natural gas exploration and investment in Europe. This made energy supplies completely dependent on imports from totalitarian dictatorships. In addition, Germany chose to make themselves completely dependent on Russia specifically despite attempts by the US and eastern European countries to stop them and somehow arm-twisted the EU into letting them go ahead with this - but even if it wasn't for that, the natural gas capacity just isn't there to cope with Russia refusing to supply and there hasn't been the willingness to invest in building more.

I don't think they've stopped this campaign even after it ended in catastrophe either. It's certainly still going on in the UK - for example just yesterday I saw a BBC article telling people that building more natural gas production here is pointless because wind and solar are cheaper, presumably based on the raw per-MWh number with no storage to fill in the gaps when it doesn't produce. That is not a useful replacement for natural gas at all.
