Technically every form of power is an indirect form of solar power.

Not fission nor geothermal nor tidal power, nor fusion, if it ever arrives. But most of the other ones.

(You can say that some of them, like fission, rely on heavy metals produced sort-of in a star. But still that wasn't from our sun.)

Not nuclear! :)

All elements used in fission reactors can only come to be due to supernovae. So I guess not from our sun, but another star.
