Take it a step further and nearly all our energy comes from nuclear fusion, with the exceptions you noted.
I use a gravitationally-confined fusion reactor, and pull power out of it by allowing the radiation to excite unbound electron-hole pairs in a semiconductor substrate. It's dangerous; even miles away from the reactor itself I can't expose myself to the radiation for too long or I get a painful skin reaction, and that might lead to cancer someday, but hey, it's cheap and quiet and I don't pay for the nuclear fuel!
Solar is actually fusion power, which is way cooler than any fission plant that puny humans have ever constructed.
