Americans drove 3.19 trillion miles last year. EVs can go ~3.1 miles/kWh, so if we swapped out all the vehicles for EVs, they'd have consumed ~1 PWh in electricity. That's 25% more electricity than we generated last year.

The total US nameplate generation capacity is just 1.3 TW - including mothballed generators, so I'm not sure why we'd need to add 400 GW of capacity per year let alone get to tens of TW of generation capacity.

Admittedly, solar can't generate electricity all the time, but even with a modest 20% capacity factor, it'd take about 600 GW of solar to generate 1 PWh of electricity per year.

Moreover, we rarely come close to using 100% of our existing generation capacity, outside of a few hours during hot summer days. EVs, being well, energy storage devices that are stationary the vast majority of the time, seem well suited to charging whenever we have excess supply - which is again, most of the time.
