Then it's just heat transfer medium for most of geothermal powerplants too, because from what i understand, most of the time condensed water is recycled (and source of energy is just "hot rocks" anyway)

then if you look at the bigger picture, all that energy can be traced back to either sun, nuclear fission (in reactors) or nuclear decay/primordial heat (geothermal)

"Root" energy source really just depends on where you draw boundaries of thermodynamic system in question

Same for all the others like coal and nuclear though. So that's a dumb distinction to try to make.

Steam is always just a transfer mechanism if it's part of the power generation

Hence the meme. Because almost everything uses steam.

Any other jokes you want to break down for no reason?

Arguably these are even greener than photovoltaics, since they don't require the same kinds of materials to make (mostly just steel) and last longer than photovoltaics are supposed to. They use a fair bit of water, but you probably aren't building them in places where water is at a premium.

Hydroelectric is just liquid steam, and wind is just cold, thin steam.
