I think your assumptions discount the relatively high percentage of owners with PV solar. You CAN run your EV carbon free. Gasoline on the other hand is not only carbon intense while burning - the same is true of its manufacturing / transportation / acquisition via hostile countries etc.Moof wrote:Nice write-up:donald wrote:If you are talking about 'environmental impacts' then give up on discussing having more range.
EVs have a lower lifetime CO2 emission because they 'only' have ~25kWh of battery. Double the emissions for producing a battery twice as large and you wipe out the lifetime CO2 savings compared with an equivalent ICE. If you have to replace a battery twice as large during its lifetime, then you've really destroyed the argument for EVs over ICE, on CO2 grounds.

Indeed, the battery carbon footprint of a Leaf sized battery is non-trivial. ..... snip.........
