    I was thinking all energy on earth (except nuclear?) comes from the sun. I suppose that there is some inertial energy from previous stars/big bang.

      Yeah, elements heavier than iron, like uranium, only form in supernovas at the end of a star’s lifespan. So, arguably still solar energy, just not our solar energy.

        Good point. I never really thought about it but nuclear is probably the least renewable forms of energy. It all comes down to stars! Good luck figuring it all out fellow star stuff that got curious.
