Guess I still don’t get the number. My wife has a plug in hybrid and the cost is far less than $0.29/mile.
For her mostly local needs (which is fairly typical for many people research shows) she uses the car about 25miles per day and fully recharges on a regular 110 outlet in the garage. Our at home electric charge cost/rate is about $0.11/ KWh
so per day it’s about $0.88 to operate the car (gas equivalent)
for her/us that comes out to:
$0.035 per mile. (Or 12% the cost CC is reporting)
moreover, since she’s had the car (January 2019) I’d say she has put perhaps 10 tanks of gas in the car, total in 3 years.. (Yes I use stabil, 😂.) We have ~30,000 miles on the Kia Niro.
so if you want to add in gas costs too that’s about 30 gallons at maybe 3.30 a gallon (which is high actually). That adds another whopping $0.003/mi, keeping the running total still under $0.04/mi.
The lesson I see here is we need to be careful with the math and understand that different situations can yield wildly different results.
Anyhow that’s my $0.04 cents for what it’s worth!
PS For those who prefer mi/gal all you need to do to convert is divide the current cost of gas and divide by the $/mi estimate.
In my example above that would be $4.5/gallon (regular unleaded gas cost here in Colorado) divided by $0.04/mi.
The rounded result is 113mi/gallon.
For comparative purposes, the $0.29/mi estimate made for cc by dgatzby = 15mi/gallon.
