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.
