Reply to comment by tacknosaddle in Electric-vehicle charging stations could use as much power as a small town by 2035 — and the grid isn't ready by Sorin61
Doubling the power grid would be much more expensive than any of those things. For every wire that exist, you will now need two.

I think you have a misunderstanding of how power grids work…

I work on them for a living. You either double the current or double the voltage, if you want to double the power. Doubling current means the copper carrying the energy has to be twice as thick. And they can't step up the voltage much more at local levels, usually not at all.

Car chargers for the home run on 220V. Are you really trying to say that the current grid cannot supply that voltage to houses?

No, you are confused. I'm not talking about the wall outlets at your house.

I'm not confused. Home charging for an electric car can be done with a regular 110V outlet, but it is very slow. If you hook it up to a 220V then it will charge overnight and those are common home outlets for electric stoves and dryers. Nobody is looking to put the "quick charge" stations in their homes, those are and will continue to be commercial applications.

So if I want to have to have twice as a many baths, I need to install another bathtub and plumbing system?

No, because you only use about 0.001% of the possible flow-time of your pipe.
