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?

    There is also kinetic energy when objects in space crash into the earth. RIP 🦖🦕

      Hypothetically those would average to O as they strike randomly though right?

        Well it’s still incoming energy, and it’s a scalar quantity. One could argue that average velocity/momentum incoming from the strikes might be zero, but I don’t think that’s the case either

          Yeah, AFAIK the big meteor showers all come from the “oncoming” direction as Earth orbits the sun. That actually might average out to zero linear momentum, depending on how they’re spaced, but it definitely is reducing the Earth’s angular momentum around the sun.
