Not to mention that even with California's insane electricity prices the cost per mile to fuel an electric car charging at your home from the grid is somewhere around $0.0325. For a typical sedan that's equivalent to paying $0.98 per gallon for gasoline. Use your own electricity rates and mpg to plug in to this formula: [MPG of your current car] * [Electric rate per kWh]/4 = gas price equivalent This only applies to cars, not trucks and heavy vehicles.
