I mean... I guess.

We eat stuff that either got energy from the sun or ate other things that got their energy from the sun.

And wind currents are created by solar heating and convection, so wind is solar.

And coal comes from ancient organisms that either used solar energy or ate stuff that did, so coal is solar.

And lakes and rivers that fall through dams to make power really came from rainfall, and the water cycle is powered by the sun, so hydroelectric is solar.
