even if your number are correct, which I doubt, there is no way any EC makes economic sense, practical sense, or common sense. maybe some day it will, but that day has not arrived. nothing is free, everything has a cost. there ain't no free lunch.
I posted the sources of my numbers. You can look them up for yourself. They are correct. I also used some assumptions from the area of the county Katz says he lives in, and assume that his statement that he drives a Chevy Volt as a given. This is a hybrid car, not a fully electric car.
According to Katz, he drives a hybrid car. That is not an electric car, though it has an option for electric drive. Apparently, Katz only uses the car for relatively short commute trip, rarely triggering the gasoline engine to start. He tops off the charge each night. That car has a range of 53 miles on the battery only when the battery is new. Range drops off as the battery ages, as this car uses Li-ion batteries.
Such a car is also capable of open road trips, operating as a gasoline car with poorer than usual fuel mileage, due to carrying around an extra power plant.
The fully electric car also works for commuting, but it sucks terribly at any open road use or all day use like a work truck would see. The basic problem is the length of time it takes to recharge the car from drained battery to full charge. Unlike ICE cars that only take 5 minutes to refuel, the electric car takes 10-12 hours to charge. This makes the electric car completely impractical for open road or work vehicle use.
Even many golf courses prefer the gasoline golf cart. They are also preferred in The Villages, a retirement community in Florida where the citizens use them to go shopping with. Instead of cars, these people get around primarily by golf cart.
Several electric car designs are great in the snow. They have individual motors on each wheel. The computer can easily respond to any wheel slipping and route power to motors that have traction. Their extra weight helps as well.
Hybrid cars can't carry as much as an equivalent sized gasoline car, since the batteries do take up some room (typically located behind the seat). It also has a battery in the trunk which is used to start the engine when it's needed. Trunk mounted batteries do lose a lot of power in the cable over such a long run, so not a good place for it. So much for GM.
If you want to see where I got my numbers, look up information at General Motors Inc., Tesla Inc., Puget Sound Energy, local shop rates for battery exchange for the Chevy Volt and for the Tesla Model 3.
Also remember that YOUR economic sense is not going to the same as anyone else's economic sense.
