People won't be able to appreciate how much CO2 they're saving if they just see they're paying 1/2 as much at the pump. If, on the other hand, we show people that their whole fillup is 2 "gallons" of electricity, then suddenly it's crystal clear how awesomely energy efficient your vehicle is. Looking only at work obfuscates vehicular performance. It ends up compounding a bunch of different factors. If we just told people how much energy- how many "gallons" of electricity- are going into their car, they'd understand much better. It'd be up to them to find out how polluting their grid energy was. But it should be much more efficient than the gas car, which still has yet to do most of it's energy conversion & is about to throw 66%+ of the energy input away to heat.
