Credit card.
At least 1/2 - 1/4 the cost of gas....
Thanks. I see that Illinois? charge rate of $0.24 kW...is that just for that area? Also, that seems pretty high given that we pay less than half that where we live. Is that a local/regional charge per kW?
(looks like you changed it to Kentucky that charges differently.)
I'm not sure how you can say that the power charge is 1/2 - 1/4 the cost of gas though. ....
Funny how the fans cherry-pick, huh? Now "
At least 1/2 - 1/4 the cost of gas" should mean exactly that (although actually, "at least" with a range makes no sense - "at least" is a single number) I'll be generous and use the 1/2 instead of 1/4, which would be the least. So in no location I pick should supercharging cost me more than 50% of gasoline cost.
So with zero cherry picking, just selecting my State and local gas prices, we have the $0.24/kWh from the Illinois Supercharger, and we have gas at less than $2.00 per gallon (I paid less yesterday, but I'll round up).
So if a kWh gets you 3 miles in an EV, that's $2.40 for 30 miles. So a gas car getting even a not great, 25 mpg (my non-hybrid car does better than that) is about on par with Supercharger. So the fan
eroscott is off by a factor of 2 to 4. Funny how those errors are always in favor of EVs. Are EV owners math challenged?
.... EV's aren't paying road use tax (yet) so the comparison is not the same.
It is a fair economic comparison for now (even if we don't think it is 'fair' to not charge use tax).
But the fans predicting some wildly high % of EV in the fleet really need to consider that if that were to happen, EVs are going to have to pay a use tax, and gasoline prices will come down as demand reduces, and kWh will go up.
Taxes on a gallon of gas are ~ $0.50 in IL. So if the IL fleet avg mpg is 25, that means to be 'fair', EVs should be paying an additional $.02 per mile, or roughly an additional $.06 per kWh. That makes a Supercharger more expensive than gasoline, not cheaper at all. And charging at home in IL @ ~ $0.11/kWh, would now be $0.17 with tax added. Cheaper than gasoline, but not by much ( ~ $1.70 for 30 miles on EV, $2.00 for gas @ 30 mpg). Especially with many (and more and more) hybrids getting > 40 mpg.
So how does this "
At least 1/2 - 1/4 the cost of gas" match up with current reality, and a future of supposed very high% of EV in the fleet. I don't think it does. If I am wrong, show me where.
