These are both known and highly controversial issues in Germany. The first one is widely accepted as without any alternative. You can't just replace a whole bureaucracy and in retrospect it worked out to only change key positions. But obviously it was a healing and cleaning process over time. The other thing is to be attributed to the fact the we were very quick to abandon atomic power even before climate change issues were that popular. Its a hilarious contradiction. We now actually also have a plan to also get rid of the coal power plants but it will be hard, maybe we need to reintroduce the candle as a source of light. There is no lack of willingness and intent but reality has us all in its tight grip.
In Germany if you live in a bubble of progressive mid-20s. Probably the same for other European nations. I am mid/late twenty myself, commute a lot to other countries via plane and laugh about it. It's not that is an actual industry hurting phenomena, without corona aviation is doing fine everywhere and growing.
Or maybe we want to keep the peace induced through learning about different cultures via cheap travel. Maybe building dams is cheaper than recovering from a world war three.
