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
