And, that drunk homeless guy could be President.
A tempting offer indeed!
Power generation demand can be affected in different ways as private transportation is electrified. It's not an all or nothing proposition.
What we see from China is that they can indeed produce a surplus of BEVs, they can add renewable capacity to the sources they already had, and they can therefore decide to use more renewables.
As fossil fuels demand shrinks, the demand for sea freight goes down as well. Moving fossil fuels to and from refineries is a significant part of sea freight.
As more family cars change over to electricity, the inefficiencies of ICE become more obvious: those who can make the switch need less energy to travel.
What might States do to accelerate the transition? The usual: adjust car buying related taxes to favour EV and make ICE less competitive. Keep the demands on legacy ICE manufacturers to make more efficient and less polluting vehicles.
End exemptions for "classic" vehicles, so that old cars and bikes keep doing roadworthiness tests each year (this is a pet peeve of mine, and might be UK-specific).
Then there are the BIG interventions that have not happened yet (to my knowledge): We can know with some certainty whether the next day will use a lot of fossil fuels or whether the renewable sources will be sufficient. At what point do we prioritise a "climate emergency" over regular productivity, and decide "tomorrow we're turning off non-essentials, everyone gets a lie-in until the solar farms are covering most of the demand at 11am."
