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?

    Y’all need to pay attention to the actual question being asked. Geothermal, nuclear, tidal are all originating with the formation of the galaxy and the formation of stars.

    Ask yourself: WHERE did the earth get X,Y,Z? Where does nuclear materials come from: supernovas. How do planets form? A gas cloud coalesces, the star forms, and the remaining gasses coalesce in that gravity well formed by the star. Without a star forming in the middle, you get no solar system. You get cold blob of gas or a cold dead rock. Where does tidal come from: same gravitational interactions that require a sun sized object - tides aren’t 100% earth & moon.

    Stars are like the seed needed to form crystals. Without them, nothing else forms. Just a bunch of basic chemicals floating around.

      OP said the sun, indicating they meant our sun. Other commenters have clarified that fissile material (and a shit-ton of the other stuff further down the periodic table) didn’t come from our sun, but other suns.

        I mean ya okay I see that. But still very neat that all energy in every form we have can be traced back to a star if not our own star. That’s so interesting! Let’s get started on the Dyson sphere.

      That video was above my pay grade I think. But ya I like what you’re saying here. Sounds like all of our energy does come from a star if not our own star
