Do you close all the power generation before or after everyone has an EV?
True that. In all seriousness, one of the main reasons my wife and I have both an EV car and a gas pickup is so that our transportation eggs aren't all in one car type basket.
If the Dims mess up our access to gasoline -- we have an EV. If the Dims mess up the grid -- we have the gas pickup. If the Dims mess up both, we have the EV for local driving (because of home solar producing most of our power, including what we use to charge the EV).
