The idea of &#x27;cheap&#x27; makes increasingly less sense going forward as the abstraction of money falls apart due to automation.<p>What matters is EROEI with externalities included (e.g. energy cost of carbon capture or sea barriers or whatever).<p>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&#x27;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.
