So, let's look at this 'high electrical bill' argument.
I own a 2011 Chrysler 200 that gets a combined 29.3 mpg (about 75% highway/25% city). I drive it (outside of pandemic times) about 22,000 miles per year. That means I use an average of 750 gallons of gasoline per year. At today's price of $3.099, that's $2325 per year spent on gasoline.
If I take that $2325 and apply it to the cost of electricity where I live (aggregate 20 cents per kwh with all costs combined), that would buy me 11,625 kwh.
If I assume a battery pack of 65 kwh, and that in real life, you never charge from 0 to 100% capacity, let's say a 'full charge' is 60 kwh. That gives me 194 full charge cycles, or better than one every other day.
If I further assume that I can conservatively get 200 miles on a charge cycle, and I have 194 charge cycles available per year, then I can drive 38,800 miles as an EV vs 22,000 miles for the same money with gasoline.
Or, working the equation the other way, if I drive 22,000 miles and get 200 miles per charge (again, conservatively), that's 110 charge cycles at 60 kwh per charge cycle, and at 20 cents per kwh for a total of 6600 kwh per year, my annual cost for EV 'fuel' is $1,320 - vs $2325 on gasoline.
I save over $1,000 per year on the energy cost alone.
Add to that the savings of EVs having a much reduced maintenance and repair cost of approximately $700 per year in my case (eliminating oil changes, tuneups, coolant system maintenance, and all failure modes associated with them, with exhaust systems, with combustion), and the savings is $1,800 per year.
If I keep the car just 7 years, I save $12,600.
And since the point-of-generation for the electricity is moved to a power plant that produces half the CO2 per kwh that my car does, I save 4.7 tons per year of CO2.
