Living under SoCal Edison rates with a Tesla has triggered an unfortunate rise in my electric bill (as expected). I wanted to see how economical my new car is against a fuel efficient ICE or hybrid. Napkin math: $4/gal / 40mpg = $0.10 per mile $0.30/kWh / 3mi/kWh = $0.10 per mile Now the tier rates in SCE don't start at $0.30/kWh, but they do go up quite quickly into Tier 3-4 if I'm driving more often. My driving habits improve when I'm low on battery but I average 350+Wh/mi (worse in the winter). One might argue that 40mpg is tough to maintain without a hybrid, but gas looks like it's closer to $3.50 in CA (winter). Does this mean I'm not really saving any money by driving electric?
