If you look closely enough the sunlight that powers solar panels also comes from the fusion of hydrogen that will be literally changed to another element. But

If you look closely enough the sunlight that powers solar panels also comes from the fusion of hydrogen that will be literally changed to another element. But I think it's still fair to call solar renewable because the sunlight hitting the Earth is continually renewed. And while the amount of Uranium on Earth is fixed the amount of uranium in the seas is renewed from that much larger stock, so I think calling extraction of sea uranium is fair.
