That’s a great point. Not taking away from the point:
- I’m not sure that your numbers are not old. - Given the demand for non-household EVSE, people are charging using the grid mix no matter what they use at home. - as the mix of renewables to fossils on the grid change, most will be charging when fossil resources are used in greater percentages. This will change both diurnally and seasonally. - As BEVs become more popular, I think that percentage of those buying energy cleaner than the grid will drop to levels closer to the grid mix. Again, your point is good, but the overall numbers I don’t think are as high as you think. But I have no data on this. - Mark Sent from my Fuel Cell powered iPhone > On Jun 4, 2020, at 8:41 AM, Robert Bruninga via EV <[email protected]> wrote: > > The #1 problem with most CO2 assessments of EV emissions is they take the > Grid mix (say 65% coal and Natural gas, etc) and apply that to the EV while > surveys show that 85% of EV buyers also *BUY* 100% clean electricity either > from their own solar panels, or by signing up for Wind from their utility. > > They ignore the demographics of who buys EVs! > > Saying that an EV runs on 65% fossil fuels is like saying I have an 18% > chance of dying from lung cancer because 18% of Americans smoke.
