And you thought, they are generously promoting EVs for the environmental good
At that cheapest rate of $0.20/kwh and 3 miles/kwh for an average EV, this is more expensive than the gas costs of Toyota Prius with ~55 mpg. The Prius will cost you $2.60 for a gallon, while your utility will cost you $3.60+tax for the same 55 miles of driving.
Wait till there will be no off-peak because of more EVs. What's the rate for non-super off peak hours?
To make it actually a fair comparison, use real MPGe and MPG. In San Diego, the average gas price in the past 6 months ranged from $2.65 to $2.88. Take $2.77 as the average.
2016 Toyota Prius gets a combined MPG rating of 52.
2016 BMW i3 gets a combined MPGe of 124
2016 Nissan Leaf 30kWh gets a combined MPGe of 112
2016 Tesla Model S 60 kWh gets a combined MPGe of 99
1 gallon of gas = 33.7 kWh, as converted by MPGe rating
So the Prius, at $2.77/gallon, costs $0.053 per mile.
The i3 is 3.68 miles/kWh, or $0.054 per mile.
The Leaf is 3.32 miles/kWh, or $0.06 per mile.
The Model S 60 is 2.94 miles/kWh, or 0.068 per mile
On a 50 mile trip, that's $2.65 versus $2.70 versus $3.00 versus $3.40.
In my neck of the woods, I pay roughly $0.07/kWh at super off peak (including metering fees and taxes), which means the Model S would be $0.024/mile, or $1.20 for 50 miles.
Of course, the price of gas is extremely variable, and we would have to see the 15 year service life average cost of gas as compared to electric. Naturally, this doesn't take into account the benefits of zero emissions at the tailpipe.
