Just quickly Googling:

-----------------

On average, it costs $15.52 to charge a Tesla, based on the national average cost of electricity. Across all models, Teslas cost slightly less than 5 cents per mile to charge.

...

How much does it cost to charge a Tesla?

Tesla car model | Cost to fully charge |
---|

Model S | $17.83 |

Model X | $17.99 |

Model Y | $14.39 |

(

chart source)

The chart's source says that a fully-charged model S can go about 400 miles.

A model X gets about 330 miles.

Let's see ... my Sprinter averages 22 mpg, and diesel around here is pushing $5 (+/- $0.50)

500/22= 22.7 cents per mile.

I start looking for a station at 300 miles, i start *really* hunting for a station at 425 miles.

--dick (my peak Sprinter mileage is 26 mpg, still over 19 cents per mile.)

p.s. my electric company is over 95% non-fossil. Hydro, nukes and wind are the bulk of it.
