If global warming is the reason we care, CO₂ per passenger-mile (km, whatever) is what we should minimize. This includes the advantages of electric motors and nuclear power and transit and the disadvantages of coal power and low transit utilization.
- rektide 4y agoPeople 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.
