optimisticly, most fossil fuel reserves will be gone in 30-50

You're forgetting nuclear as well. There's enough uranium to last at last
150 years if not more. Beyond that, fusion will most likely be a reality.

Actually, there's 6000 ppb of thorium in the Earth's crust and
1800 ppb of uranium, totalling very roughly 10^30 joules to play with.
