> The highest peak electricity demand in the UK in recent years was 62GW in 2002. Since then, the nation’s peak demand has fallen by roughly 16% due to improvements in energy efficiency.

> Even if we all switched to EVs overnight, we estimate demand would only increase by around 10%. So we’d still be using less power as a nation than we did in 2002, and this is well within the range the grid can capably handle.

> In the US, the grid is equally capable of handling more EVs on the roads – by the time 80% of the US owns an EV, this will only translate into a 10-15% increase in electricity consumption.1

The way I think about this is that I use an L1 charger at home that draws 1500 watts about half the time (on a normal day).

That's ~= 15 light bulbs from the 1990's, or roughly 6 desktop PCs. I switched from incandescent to LED bulbs, and a desktop to a laptop, so that's almost enough to offset the EV's usage. Also, we have solar panels, and a house battery that can time shift our energy consumption.

A modern fridge and washing machine are both vastly more efficient, too.

Switching overnight is a silly scenario, and I agree we shouldn't pay much attention there.

The power grid also naturally grows from year to year. As more and more battery systems come online and are available to store and discharge power (your car, a household power backup system, solar, etc), the load on the grid will smooth out.
