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?

Would hydro and geothermal count? Wouldn’t count wind because wind is caused (mostly) by the sun heating things up.
I wouldn’t count either then. Hydro is ultimately powered by precipitation, which is caused by the sun evaporating water. Geothermal is ultimately caused by the gravity of the sun affecting the earth.
I agree with hydro, but you’re wrong about geothermal. Tidal forces caused by the Sun are minuscule compared to that of the Moon. Also, Earth still has a decent amount of latent heat caused by its formation.
Does it? I thought it was overwhelmingly radioactive decay driving it at this point.
No, that’s how it works on the Jovian moons, but Earth’s interior is heated by some mix of radioactivity and retained primordial collision heat.
Well there is still nuclear, piezoelectric, and kinetic, at least.
What are you going to use to actuate your piezoelectric or pedal generator? If it’s alive, it’s probably eating sunlight somehow itself.
Rocks collide in space all the time. 🤷🏻♂️
I guess if you can catch a meteor, that is plenty of energy, haha.
Hydro is also the sun - rain is delivered by (solar) evaporation and wind.
