No. Nuclear isn't (unless you're going to stretch "solar" to include past supernovae. Geothermal comes from nuclear fission (or possibly residual gravitational energy? Either way, not solar). Given the discovery of hydrocarbons off-Earth, it's possible that some proportion of oil is non-solar in origin, too, though that would mean it's ultimately geothermal, and thus a nuclear by-product. Not sure of the status of that speculation currently, though.
