According to the Wikipedia entry for the Tesla Roadster:
"Recharging with electricity from the average USA grid [...] yields a
full-cycle energy-equivalency of 44.0 mpg."
The formula for "full-cycle energy-equivalency" considers a bunch of "upstream"
factors in the production and transmission of electricity and petroleum-based
fuels.
So it's decently economical, on par with other small gasoline-powered cars but
certainly less than the most efficient diesel-powered cars.
