Modern — overdeveloped — societies in the West are already in a severe crisis. Something, which will eventually turn into a long global emergency in the years and decades ahead. A five centuries long era of economic growth — ushered in by colonization and leading to the plundering of natural, mineral and most of all fossil fuel resources —
What types of electric generation that aren’t heat related? I can think of wind and solar, and hydro? But nuclear and fossil fuels are steam, aren’t they?
You answered your own question - correct on all counts! 😊 There are really very few physical principles to base power generation technology off to begin with; it’s all going to come down to either inducing a current in a conductor by spinning a magnetic field (molten salt solar, nuclear, fossil fuels, hydro, wind, and anything else involving a turbine at any point all operate on this principle), or inducing a current by futzing with quantum mechanics (photovoltaic cells alone operate off this principle, as far as I understand such things - and I understand just enough to know I understand nothing at all).
