...33.7 kilowatt hours of electricity is equivalent to one gallon of gasoline... http://en.wikipedia.org/wiki/Miles_per_gallon_gasoline_equivalent

Our local electricity costs about 11 cents per kWh (tax included). So .11 x 33.7 = 3.70 per “gallon” equivalent.

Smart states that their electric gets 122 city and 93 hiway per EPA estimates. This about 3x what their fuel based Smart’s get for efficiency, so I have my doubts about the accuracy, but will go with the lower value for guestimating http://www.smartusa.com/comparevehicles/

I drive up to 300 miles per week for round trips of less than 60 miles.

If their estimates are correct, and more importantly if my math is correct, then the fuel cost of the Smart electric would be as follows, again using their lower fuel consumption number of 93 mpg:

300 miles divided by 93 mpg = 3.22 gallon equivalent units of electricity.

Accordingly, 1 gallon equivalent of electricity is the same as 33.7 kWh. So 3.22 units x 33.7 kWh = 108.51 kWh.

108.51 kWh x cost (11 cents per kWh) = 108.51 x .11 = $11.93

Is this accurate? Less than $12 to drive 300 miles?
