You're right, it's NOT free, it's SOMETHING YOU ALREADY PAID FOR.
The really insane thing is that the USA spends more money per capita than ANYONE and still gets worth healthcare coverage and worse overall results, with lower life expectancy. There's even this effect where rich people don't get as good care as average people in other countries for a number of common conditions or procedures, because the whole system is so bad you can't even PAY for great service.
But that aside:
Solar is so gobsmackingly cheap, it'll pay for itself in almost zero time. The real cost is the grid, but generating enough power is so stupidly trivial it hurts. You put a solar panel out in a field and it collects electricity and that's the end of the story. You pay for that panel once every 20-30 years and it generates electricity for you. You don't dig things up out of the ground or fight wars, you just let it collect the electricity.
Technology Connections did an excellent video on renewable energy, and using just the figures for putting solar panels on corn farms that produce corn for ethanol and not food, his back of the envelope calculation was that you could produce 7700 TWh of electricity a year, which is considerably more than the 4100 TWh that the US grid currently produces.
The reality is there doesn't need to be any energy crisis at all. AI data centres don't even need to be an environmental problem, you can just hook solar panels and batteries up and run them and they'd even use less water than the corn fields that were displaced for the solar farm.
The whole discussion is ridiculous. More solar panels. Solar panels everywhere. It's effectively free. The only reason governments don't do it is so they can keep lining their pockets with oil and gas industry kickbacks.
Here's the video link to the right time stamp, if you want to check what I'm saying and review his math.
