Look at this way. In terms of cost per mile, the public chargers are priced to be about the same as gas. But ICE cars cannot charge at home, whereas EVs can.
Also, MA is a bit of an outlier here due to our crazy high electricity prices. On a national average, EVs make more sense.
Depending on the efficiency of a particular EV, routine driving (i.e., our and about within an hour of your home) saves an EV drivers hundreds of dollars compared to the cost of gas. That savings can be used to rent an ICE vehicle as needed for long trips. As long as it's not done often, I would still come out far ahead.
Take these real numbers for example:
- A good EV gets roughly 4mi/kwh. Some Tesla's get more, some bigger truck EVs get less.
- Average MPG in the US right now is 25mpg.
- Regular gas is roughly $3.50/gal right now.
- So to drive 100 miles would use 4 gallons, which would cost $14.
- For an EV to beat that, the cost of electricity has to be less than $0.56/kwh.
- Average electricity costs is $0.15/kwh (I know I know, MA is way higher).
- Driving 10,000mi/yr in an ICE vehicle would use 400gal and cost $1,400.
- Driving 10,000mi/yr in an EV would use 2,500kwh and cost $375.
- The net difference is a savings of $1,025/yr.
- Looking at some non-airport car rentals nearby, I can get a 2 week-long rentals of a fullsize SUV and a several tanks of gas, and still have some savings left over.
