Until they massively upgrade the power grid, at huge expense and time, it is only a pipe dream.
Refitting and redesigning the power grid will take decades and hundreds of billions of dollars and no one has started budgeting for it or building new power plants. To the contrary they are fighting any expansion.
BTW, wind and solar will not cut it.
Current thinking is solar and wind would get a huge boost from deployment of tens of millions of EVs. Everybody would charge them up during the day with solar and wind juice. At night, your car batteries would feed power into the grid.
Of course, these analyses tend to not ask the question “Why is my car dead this morning?”
Pipe dream indeed electric cars didn’t pan out in 1905 they pop up as a fad every so often.
