Even now non-oil Energy accounts for a tiny fraction of total energy supply. And non-oil energy (even nuclear) heavily depends on oil for mining, enrichment, transport.

As we have less and less oil and try to replace it with non-oil, we have to do it faster than humans have ever done before. e.g. in 25 years we have to replace half-oil-output with non-oil. in 45 years from now we have to produce TWICE the stuff/energy we make from non-oil, because demand will have gone high. Human beings have NEVER changed energy sources faster than 50 years. Coal to oil transition took 60 years. Biomass to coal transition took 50 years.

Even now total electricity used in transportation is negligible. Electric trucks are too heavy to carry their own battery weight. Electric airplanes still cannot move large number of people. Nuclear ocean-liners are still only used in the US military. Cheap ocean transport is why globalism is possible. Without it, the world will be split into fortress islands of civilization, that keep out the rest of us barbarians.
