Well I suppose the answer is that they use "electricity" which will be

I wonder how you think electricity will be made "after the liquid
stuff runs out".

Have you heard of this black rock named "coal"? You can burn it to
boil water!


That was actually what I was thinking of. With oil running out, and
only finite supplies of gas available, we will no doubt go back to
coal at some point, with the attendant increase (over gas) in carbon
emissions. But I expect to be dead by then, so global warming will be
someone else's problem.

Gasification of coal (back to town gas, essentially!) with carbon-
capture and sequestration might work - as would gasification of
biofuel (wood gas), of course. Coal gasification particularly
could be a useful gap-plugger in the short-to-medium term
until serious amounts of tidal and wave-power generation could
be brought on-line.
