The idea of 'cheap' makes increasingly less sense going forward as the abstraction of money falls apart due to automation. What matters is EROEI with externalities included (e.g. energy cost of carbon capture or sea barriers or whatever). But even if we play that game, in the UK we already pay something like a 75% combined tax rate (probably higher now) on car fuels. So we've already priced in 4x. And household electricity bills are generally trivial compared to stuff like land cost. We can, and will, afford it in monetary terms.
