Nuclear is not renewable though, those isotopes were created when some past generation star collapsed as supernova.

Solar will no longer be renewable in 5 billion years as well.
But it is today
And wood, coal, and oil are renewable. It's funny that we have fixated on "renewable" when carbon in the atmosphere is the problem, isn't it?
No, coal and oil is not. Since we have micro organisms that can consume wood, coal and oil will never be produced again.
> During the Carboniferous period, massive amounts of plant matter accumulated to form coal because microorganisms and fungi had not yet evolved the ability to break down lignin, a tough, aromatic polymer in woody plants.
