The stardust is a given. As for sunlight, all the energy including somewhat arguably geothermal (using the suns gravity to help form the earth and I guess radioactive material being formed by other stars) comes from the sun and gets converted into chemical energy you eat so you’re stardust animated by sunlight (mainly).


I don’t know how much but I’m sure at least some geothermal energy is due to tidal forces on the earth.
Which would make some of it technically lunar power.
Only when a moon orbits around a planet faster than the planet spin on its axis, then only will this moon transfers its orbital energy to the planet.
Our planet, by the means of tidal forces, transfers a small part of its rotating energy to the moon’s orbital energy.
… in this process most of the rotation energy lost by the Earth is converted to heat.
so … you’re saying that earth will eventually slow down the spinning until its angular velocity equals that of the rotation of moon around earth?
That is accurate. However, there is also an effect from the Sun. I think the Sun will do it first, but I have not checked.
How did the moon get there? Would it be there if there was no sun? It’s a shit argument I know but the moon and its mass is in some form due to the existence of the sun.
“Lunar power” arguably came from the initial condensation of matter spinning into the sun - it’s the stuff that didn’t get sucked into the fusion reaction. Now - where did that kinetic energy come from? Likely supernovae nearby not too long ago…
Tidal forces on earth are a combination of the moon and the sun’s gravity
And neither are powered by the fusion of Sol - they got their energy when the solar system formed out of the ejecta from previous stellar explosions - probably not much “big bang” direct contribution to rotations in the local frame.
