"Anyway, it's all Entropy"
Whilst fundamentally true, it is manifestly unhelpful. Things are categorised for good reason, and there are accepted meanings for 'renewable' and 'solar' which we may as well adhere to. It would be super if you didn't muddy the waters further.
Also, I believe heavy elements are apparently formed in supernovae and were not themselves formed in the big bang, which would presumably have only resulted in light elements... maybe even only hydrogen. But I Am Not An Astrophysicist, etc.
