Well technically speaking crude oil is a form of solar energy. (Sun -> plants -> animals -> crude oil)
What energy sources do we have that don't ultimately derive from either solar of radioactive decay? Residual heat from object formation perhaps.
Isn't solar derived from nuclear fusion?
Nukes for the win!
