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?

    Tides are from the pull of the moon’s gravity. And the moon formed from another body colliding with the Earth. It’s not just due to angular momentum and the moon forming out of cosmic dust like the Earth did.

      Without angular momentum it would have fallen back down to the Earth instead of going into orbit. It’s the orbit specifically that powers the tides, not just it being there.

      But yeah, you’re right. Beyond providing the materials dust was not involved.
