There does not appear to be any viable substitute for oil

Don't forget about coal. There's a lot of that.

Worldwide, coal is the most abundant of the fossil fuels, and its
reserves are also the most widely distributed. Estimates of the
world's total recoverable reserves of coal in 2002 were about
1,081 billion sort tons. The resulting ratio of coal reserves to
production exceeds 200 years, meaning that at current rates of
production (and no change in reserves), coal reserves could in
theory last for another two centuries.
