Geothermal and tidal energy are also not fundamentally based on local solar power.
Though one might argue that they're also ultimately stellar-based power in the sense that in the case of geothermal energy both the residual gravitational thermal heat and heavy-element radioactive decay, and in the case of tidal power, the formation of our own proto-solar-system nebula were themselves based on earlier-generation stars.
But then so is nuclear fission based on heavy elements such as uranium, plutonium, or thorium.
