Well, hydro is just spinning water again, wind is spinning air. Solar is stealing electrons from the sun (i think?) So that's cool
reappropriating :D
Well, the sun is sending them to us, so it's not really stealing!

Agree, the quantum-chem of it is amazing... Then again, solar has an efficiency of ~30% compared to the 90% for spinning steam
I don't think it makes sense to compare those efficiencies, as one is for converting heat to electricity, while the other is for converting sunlight. If you use sunlight to heat water and then use that for a steam turbine, the efficiency is similar to a photovoltaic panel. The efficiency numbers are still useful, but only when they refer to the same starting point for the conversion (e.g. only comparing things that turn heat into electricity).
You are right it doesnt really makes sense to compare them that way, it was just what the initial comment was doing. Nuclear fission is in itself only like 30% efficient. There are of course tons of metrics to compare these things, I personally like space-time efficiency or CO2/MWh.
But it's all profit baby! Let something else figure out cousin, put 0% effort in and collect the rewards!
but crucially no moving parts. very little maintenance, especially compared to anything steam driven.
I am a big solar fan, but the moving part inertia thing is actually great for stabilizing the grid.
They pump water through it. The water gives energy, all our energy is hydrogen baby
