> Industrialized countries have power grids and the like that were built before such demands for power existed

This stinks of fake news to me.

At least for locations with air conditioning systems this seems false. Hvacs require more inrush (start capacitors) and run energy (run capacitors) - and coordinate very poorly with neighbor and industry use (during the heat of the day)

Electric Cars require none of it, 90% of use cases can charge 1-3 nights a week off of a standard 120v 15 amp circuit.

It's also possible to coordinate both your hvac and Bev to not turn on at the same time and to deprioritize for your utility or rate plan.
