Most energy sources trace back to the sun’s power through direct or indirect processes. Fossil fuels, wind, hydro, and biomass all originate from solar-driven cycles on Earth. About the only thing you could argue that isn’t solar is geothermal. But even that exists because some sun exploded created gas and dust that clumps together and forms a planet.
But in the end isn’t all energy solar?
