Maybe, those on lower incomes will continue to drive polluting vehicles, (as long as "authority" allows ) while the "pollution free" ones will be company cars? (i.e. initial cost and subsequent battery replacement costs ) Perhaps "used" electric cars will have low residual value because of the cost of replacing the battery?
A while ago, at our Engineering Society, a chap from Lotus showed that fossil fuels provide the highest energy density of all currently available fuels, surpassing hydrogen and electricity by a huge margin.
(After all, the energy to produce and distribute the electricity and to produce the Hydrogen, has to come from somewhere ).
Currently, there seems to be little interest in reliable recurring natural forms of energy production, such as tidal or wave power, rather than intermittent and inconsistent wind power.
Even PV cells cannot maximise production, since sunshine all day, every day, cannot be guaranteed,
Having put the cat among the pigeons, I'll watch the results!
