I believe the whole non-renewable energy debate will be obsolete by the end of this century.
It is looking increasingly likely that energy derived from nuclear fusion will be commercially viable in the next few decades. The fuel is nothing more than water. It will solve mankind’s energy consumption problems forever. There is multi-billion dollar investment by the international community (notably the EU, China and the US) in major projects (HiPER and ITER) to make this a reality. Science and technology at its best.
I hope there are members of this community who will be alive to see this happen.
