This alone would had given AfD my vote
And that's one of the reasons why Germany's establishment finds them intolerable. They challenge an unspoken of (in Germany) energy policy grift with billions on the line and Russian influence op involved.
So who do those who challenge the climate hysteria actually challenge?
1. Putin. See: whole Nord stream 2 debacle. Check out what's Gerhard Schroeder doing these days. For all the talk about how Putin is bad, Germany is dependent on Russia's gas, and in fact is needing more of it with the increasingly ambitious CO2 targets. And that's because gas and renewables are the only acceptable energy sources in climate hysteric's world, while you can't power a major first world country with renewables alone. So Putin can feel safe that Germany can't press him too hard no matter what because he holds Germany's heating and industry hostage, and he gets paid for it.
If Germany was free to switch to an energy mix that makes good relations with Russia completely optional... that wouldn't be a happy time for Putin.
2. Green idiots, probably still useful idiots for their former handlers. No nuclear for you because they exist, and even have a relatively successful party. Probably lots of leftist activists in education and media to blame for that.
3. Renewable energy sector. Selling renewables is a good business that is possible mostly thanks to massive subsidy regimes thanks to the whole climate hysteria related policy. Take that away, suddenly they have to compete with coal, take away green idiots, suddenly they have to compete with nuclear, they know it, their political sponsors know it, so its a great moneyed relationship for sure.
