You can point your finger at the CDU, but saying that the CDU was the big driving force is disingenous.
It seems that Germany's descisions on exiting nuclear power plants are always unhappily timed. First, Fukushima happens, making the extension a few months earlier look really weird. Then, the Ukraine war happens, rendering Germany's original plan moot to replace coal with natural gas from russia, and everyone is shaking their head again as Germany is keeping to the original plan.
That the current generation of voters who supported the shutdown of nuclear power production were substantially "encouraged" to adopt such views by said Greens' actions and politics when they were children and teenagers living in the 80s is incontrovertible fact. So, even if Merkel ended up as the one who executed the will of the people as head of the CDU, that will had nothing to do with CDU policy, and certainly not in the 80s and 90s. That was by definition the policy of the Greens, who also laid the groundwork for the irrational fear that Germans in their 40s and 50s have been cultivating for decades.
Why can i say this with complete certainty? Because I was one of those kids.
Kids are glueing themselves onto streets because their obsessions aren't satisfied strongly enough. The brainwashing is real.
Unfortunately obsessions lead to lack of wider thinking or logic.
And fighting it isn't something that only Germany is tasked with.
btw. it's not kids, but grown ups of all ages that are gluing themselves onto streets; in various countries
I'm rather sure that not being able to afford energy - heat in the winer - is a the real existential threat to a kid in continental Europe.
Worrying about sea level going up 10cm in his/her lifetime is a rich person hobby.
Worrying about the future past next year is definitely a rich person hobby, if you define "rich" as "not imminently starving".
Sea level rise is the least of the trouble. Look at fisheries decline (yield per inflation-adjusted-dollar spent has been recorded for a long time now - in spite of new tech it's been dropping for over a century), temperature-driven crop failures, increased frequency of severe storms damaging infrastructure.
But the primary near-term risks from climate change are heat damaging crops, (wet) heat killing humans, declining soil moisture in some regions, and increased risk of flooding along some rivers. Over two centuries, coastal cities may be inundated, but that is a long time.
So no, this isn't something rich people will face in 50 years. It's something everyone faces today.
But let's take the last year, sanctions policies that lead them to trade direct resource imports from Russia to having the same imports but paying premium through brokers like Morocco, India and Chinese LNG(all coming from Russia). Let's remember what the BASF CEO said before it escalated.[1]
A lot of people in Germany were begging the government to postpone the shutdown of the remaining power plants until they have replacements, but the ideological Greens just charged ahead replacing Nuclear with Coal to achieve their ideological goal of removing nuclear. They have also been at the forefront of pushing legislation at an EU level to block nuclear in various forms.[2][3]
I've seen these obsessions in various other parts of society. I've had people stand behind me waiting telling me they could not pass anywhere but where I am even though they could just take a turn around me. I've personally experienced and heard from multiple people at the CCC that their Math teachers would punish them for achieving a result with a different technique than what the teacher taught them.
