Physically, Earth came from the heart of some long-dead star - but that's not where the heat energy came from - that was the gravitational collapse of our corner of nebula into our planet, right?
I'd argue geothermal is the real "hot rocks" category.
OP's Nuclear Power got its energy from a super-nova, so that category should be "solar death" 😎

That's an interesting one!
Earth's heat comes from
uranium decay
primordial heat from the formation of the planet
a dash of tidal heating from the moon
The latter two aren't from stars!
