Peak oil is “a largely forgotten issue” because it was a largely overblown issue to begin with. Fracking relieved the immediate supply pressure while reductions in demand will help matters even more.

Fuel shortages are unlikely to be a serious risk for centuries. Hydrocarbon reserves are measured in the trillions of barrels (in the US alone) and the different types are largely fungible at <$100 barrel inasmuch as you can convert them all into fuel.

We may greatly reduce hydrocarbon fuel usage but it won't be because we ran out in my lifetime.
