Most recent estimates are that under typical electrical grid power sources, it takes 8,000 miles to pay off the manufacturing CO2 debt for an EV, not 30,000 miles. I believe that larger figure is if you’re grid were 100% powered by coal.
- jfklsdfjsdf 5y agoThat would be the most optimistic estimate I've ever seen - do you have a source for it? Assuming 73kg/CO2e per kWh of EV pack[1], an 85kWh EV pack, an ICE that gets 40mpg (and thus 40 miles per 11kg CO2), grid production of 0.30kg CO2e / kWh (which is far lower than the US grid output), and 3 miles per kWh for the EV, the breakeven point is at 35,000 miles.
