The sun is literally a nuclear fusion reaction. Wind and hydro are an artefact of the sun + the motion of the planets. We could even stretch the argument that fossil fuels are also indirectly solar from photosynthesis.
Maybe it was a typo?
- xxs 4y agoNot a typo - pretty much all the energy that we get on Earth is the just the Sun - which indeed is nuclear (perhaps i should have said fission). "Geothermal" pumps are solar, too (the earth being heated conserving energy), I suppose the term is used a bit too widely - with the Earth core/spinning being a vastly different source. Your point stands though. I meant type of energy that's readily available on Earth - either Sun based (fossil, solar, wind, hydro - all directly depend on the Sun), or nuclear fission. We don't have any fusion available, yet - that would be a real change.
