EV charging and hydro generation/distribution challenges

[tomh009]

As long as there is enough electricity (being generated) for everyone, that makes sense.

What does that mean? A wealthier society can afford to generate more electricity than a poor society. In 99% of societies that have existed to date, “enough” electricity was none at all; and even now, “enough” in most places is an amount that probably wouldn’t run my dishwasher.

There is no way around it: you can ration by price, letting each person decide how to use their resources; or you can pretend that a central planner is capable of figuring out what people need and want. Hint: they can’t.

This goes back to my original point: if we add millions of EVs, their power consumption may exceed the current spare capacity. And, if that's the case, we'll need to build additional generating capacity, whether zero-carbon or not. (And I do believe building additional generating capacity would need to be centrally planned.)
