Fossil fuel would I guess be chemically stored fusion energy from a long time ago

    I could be wrong, but I think geothermal may be the exception to that. That heat is from the formation of the planet and radioactive decay.

      Radioactive elements were formed in the last moments of a collapsing star, so even those were formed during fusion.

        That is true. I guess it depends on how much of the heat is generated via fission processes and how much is just stored from planetary accretion. I don’t have any numbers for that at this moment, but I will certainly concede that geothermal is fusion-assisted lol.

      Maybe tidal energy would also be an exception? It’s from the motion of the moon, which is the result of ancient planetary collisions?

        Ooh, yeah. Didn’t even think of tidal energy. I don’t think we get any significant amounts from it currently, but it’s being actively developed.

        I guess if we want to get super pedantic about it, it would also be fusion-assisted since without the sun’s energy keeping the oceans in a liquid state, it would be frozen and unable to generate any power.

    I guess, if you’re taking into account the formation of all matter with the beginning of the universe.

      Wind: The sun (a giant fusion reactor) heats the atmosphere which generates the wind (highly simplified).

      Hydro: Driven by the water cycle where the sun plays a key role in the “evaporation, condensation, precipitation” process.

      Wind is due to the asemetric effects of heating different parts of the globe different amounts. Hydro is from rain and snow which is evaporated with the sun
