Elon Musk said that electricity consumption will double if car fleets are electrified.
If they ever get to where they fully charge an electric car in a few minutes, each charging station will literally need an electrical grid substation right next to it.
A gallon of gas contains about 124 MJ (megajoules) of thermal energy; if you're pumping gas at the rate of one gallon every ten seconds (6 gal/minute) into your tank at the gas pump, equivalent mechanical energy of a bit more than 3 million watts is flowing through that fill pipe into your gas tank. That's about 4000 hp. This assuming your engine has thermal efficiency of 25%, which is actually a bit low for modern automotive gas engines.
If six cars are "filling" at once from an electric recharging station, that's almost 20 MW, which is roughly the amount of power you figure on for a town of roughly 2000 homes.
The actual amount of heat energy that flows through the fill pipe is that multiplied by four.
My point is that a gasoline pump and fill nozzle is an extremely rapid way of moving and metering energy.
