> An analysis by KPMG says the U.S. currently has enough generating capability to charge 80 million EVs during overnight hours—hence the need to control when cars are charged. The Edison Electric Institute estimates there could be 26 million EVs on the road by 2030, up from about 3.2 million today. [1] [2]
Most people will charge overnight (either at home or the office), the average daily round trip commute is ~40 miles (1-2 hours of charging at a level 2 charger to replenish this range, depending on current available). Fast DC charging can be performed in 15-20 minutes, depending on state of charge of the battery and the charging station. My Tesla, when supercharging at the grocery store, is finished faster than I finish shopping (for example).
Thanks for the links. I should have included AI in my Doomsday scenario. AI is very power hungry. Of course AI server farms will not be spread out the way electric charging stations are but will be more concentrated but I do know tech CEO's are already looking at Canada to supply the expected electricity demand. That suggests to me there isn't enough capacity in the USA to meet that forecasted demand.

Where I'm at, the number of charging stations at the grocery store is already inadequate. They are always full. I see people with electric cars wanting to "get a spot" with a charger and there isn't any. This is what I mean about the lack of planning. The govt assumes that the market will meet demand but I just think mandating all cars be electric and relying on the market to meet that sudden demand is naïve.
Conversely, it is silly that we simply default to combustion vehicles because they are easy and we are lazy. Work is hard, and nothing in this thread described cannot be solved with existing technology. Maybe we could be less lazy? Maybe!
People hate this idea, but this likely one of the biggest improvement we can make on how we utilise excess power.
Imagine everyone plugs in after work, start charging whenever peak ends, either 9PM or 11PM. By 3AM most of the cars are done charging, yet there's 4 hours of off-peak capacity left not utilised. Whats worse, we'll see massive peaks around 9PM if we do not manage charging on wider scale.
