This is a ridiculous take. Germany did not screw up their energy policy, they had a transition plan that ended up not working due to one of the partners in that plan starting a war and believing that they had Germany by the short hairs to stop them from interfering.
For individuals in Europe that have the possibility to spend a few hundred (or even a few thousand) bucks up front to lower their energy bill is a win for everybody, it lowers emissions, decentralizes energy production and generates ROI. My own system (which is a little bit larger) paid for itself in the first three years and has allowed me to do all kinds of things that I would not have been able to do otherwise if I had had to pay for the electricity. The surplus that I don't use I sell at a discount to the grid and that's fine by me.
Well, Germany made an assumption that their „partner”, which already was starting wars, would at least keep them far enough from their home turf. It backfired spectacularly and we can blame German government for that.
Not much to disagree about generating energy at home though.
The 'handel durch wandel' policy was always predicated on the fact that economic pressure would be a strong tool to force russia to abandon its policy of expansion. It did not work. I don't blame the politicians so much for trying as I do for not realizing way earlier that it clearly wasn't working. The revolving door to high positions in the russian oil industry should have been forbidden to them and obviously they should have known better. But hope springs eternal and I can see why they fell for it, even if I think it was dumb (and I already thought so at the time, but I'm more of a pessimist I guess).
I share your take on the gas policy failure. It was hard to prevent because Russian gas was so cheap. How could the German government have forced companies to buy more expensive gas elsewhere?
