I don't quite understand. Where do environmental factors come into play with MPGe? I thought its a plain measure of energy.

- duskwuff 14y agoRemember that the "G" in "MPG" stands for "gallons" (of gasoline or diesel fuel). When your car runs on electricity, the measurement no longer applies directly, so a conversion is used to treat "gallons" as a proxy for pollution.
- redwood 14y agoI don't think it's pollution they're looking at here: it's cost. E.g. the cost to go the equivalent distance as the cost of a gallon for an otherwise equivalent car. Perhaps I'm wrong. But bringing emissions in adds significant value to the electric option: value not yet realized since externalities like CO2 emissions are not currently paid for.
