Like fossil fuels come from organic matter that grew because of the sun. Is there any form of energy on that cannot be traced back to the sun in some way?

    Although geothermal could be because of the rotation of the earth compared to its core along with tidal forces.

    Although I’m not sure how much of that is from the sun or just in general.

    Not sunlight though. Just the sun’s gravitational affect on the earth as well. But nuclear is definitely extrasolar

      It could be, but it’s not. A big part is nuclear decay, strangely enough. Some is from primordial heat, and some is from the motion of the core, but mostly from regions rising and falling, not rotation.
