Maybe there is a discussion to be had about WHY it needs to make economic sense? Power is a natural monopoly, maybe it doesn't need to be a part of the economy?

Power distribution is a natural monopoly, power production is commodified/competitive business.

It was not a good idea for Germany (and certain other parts of the EU) to be so dependent on Russian gas. It was also not a good idea to become dependent on LNG from Qatar or the US. Spain uses natural gas from Algeria (via Morocco), also not great. Italy also gets some from Algeria/Tunesia, still not great. Inside of Europe, we are far too dependent on Norway. Not because Norway is likely to turn on us (or we on them), but because the pipelines are relatively easy to disrupt.

The transition from coal to gas gave us cleaner air (and less CO2) but it definitely also had costs, some of them in the form of many thousands of dead Ukrainians, some of them in the form of concessions to the US.

And $ cost is a poor metric to chase when what you really care about includes a lot more-- exposure to the whims of geopolitical forces you can't foresee or control, which have both $ cost and more.

Because if a thing is valued by thing-consumers at x and you set the price to <x, then you are incentivizing people to use more of the thing than they need, even to waste the thing. This thus requires more infra than is actually needed or wanted.

This doesn't go away under socialism/communism/collectivism. If you set the price too low, you either have to build far more production capacity at public expense than needed, or you cope with regular blackouts.
