> Much needs to happen infrastructure-wise In what way? Plenty of utilities have stated that ubiquitous home-charging won't require major modifications to the grid. As residential demand creeps up, some spending and changes will have to be made, but nothing major. En-route charging infrastructure is getting built up rapidly without public support. Commercial EV demand alone could drive the formation of a very nice charging infrastructure.

I have vague memories of countries running out electricity at peak hours in certain conditions. In the UK they struggle with water boilers [0]. I'm fairly certain that if we switched all gas cars to electric we'd struggle quite a lot with peak electricity demand, especially during holidays and other events.

  I always assumed they would be charging overnight when not much else is going on. If we were really smart about it we could adjust the charging according to demand.

    That's what is happening already. https://insideevs.com/average-hourly-electric-usage-ev-households-versus-non-ev-households/ https://insideevs.com/average-hourly-electric-usage-ev-house... The thing is that it's cheap to charge at night right now because it's off-peak. With a shift to EV it'll be the opposite. It doesn't work very well with solar or wind energy since you can't modulate their production.

      Obviously solar is out at night but I can't see the problem with wind. I would have thought it was helpful as you could vary the demand according to supply.
