Regarding the affect of EV adoption on electricity consumption the site https://robbieandrew.github.io/EV/ has some interesting data. I'd recommend looking at the following graphs:

* Distance travelled by passenger cars in Norway

* EV electricity consumption and total power generation in Norway

EVs now make up approximately 1/3 of miles travelled, but the increase in total electrcity consumption is fairly small.

now that 98% of cars sold are BEV, i wonder how long its gunna take for that 1/3rd to get to 95%
