> EVs consume a lot of electricity. An EV’s battery can store the equivalent of an average American household’s daily electric power consumption two or three times over. If EV owners charge to full from 50% each day, a household with an electric vehicle will now be consuming twice as much electricity as it did before
This premise is Fear and Uncertainty though.
1. Ev batteries (Lithium Ion) charging profile is a slow ramp up and down; So super stable low demand power factor. (They are digitally controlled -- and with grid tie in possible) where they can charge when the HVAC is not running, to use the same running load as the HVAC.
2. 50% Charge every night applies to a very few percent of Americans; Where the average American commute is 41 miles a day and the lower packages of the average cars today are 200 miles of range; that's closer to 20% charge a day. (At 300 miles of range, that's 10% of a charge a day)
To expand on 2;
Not all charging will happen at home, or at night - not everybody has 240v service, a parking spot -- the solution to this are commercial charging networks -- which have their own substations - with 500v service. and (as is Tesla's case) local leveling technologies (battery, solar generation) . Not having these charging networks means many abandoned gas station properties in the next 10 years and the impossibility to go on any meaningful distance road trips; And this means instead of charging 20% every 5 days a week, some drivers might "fill up" once a week.
