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.

    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.

    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.
