It's a pretty flawed comparison, though. It assumes a certain amount of fossil fuels being burned at the power plant that's feeding your electric car. That's a number that varies a lot between regions, and is bound to change as more and more renewables are spun up. Putting solar panels on your home throws the whole comparison out. It's nearly useless.

Isn't the point for the consumer to measure their cost? Not the overall efficiency of the production and distribution for each source of fuel?

Like I buy X gallons per month of gas because my car gets 20 mpg and I dive Y miles. If this electric car uses Z amount of electricity and I still drive Y miles, I'll save ß dollars.

It is not really possible for the consumer to calculate their respective mpge, since your specific utlities power mix will differ region by region.

That's the idea, but it doesn't actually do that. Even if it did, the cost would be variable by region, so it's still imperfect.
