So that works out to 52.6 TWh of electricity per year, assuming increased efficiency and no increase in km driven, or charging losses, grid losses etc. The UK(this includes more than GB, was just a quick search for numbers) currently generates 334TWh. So that's only a ~13.5% increase in production. Less than I thought it would be.

Also a lot of EV charging happens at night, when demand is lower. So often they are effectively charging on under-utilized baseload. (Although not so great if you're planning to also transition to solar...)
