Inside Line: our Chevy Volt's battery miles cost more than the gas ones

During its time with us, our 2011 Chevy Volt tester consumed energy at the rate of 39.0 kilowatt-hours per 100 miles when in electric-only mode and averaged 31.1 mpg in gas engine assistance mode. We paid an average of $0.31 per kilowatt-hour of electricity and $3.31 per gallon of 91 octane swill, so the magic of arithmetic tells us that each one of the Volt's miles driven on electricity cost us more money than if it'd simply consumed gasoline instead. That's due in part to our high electricity rate - had our rate dropped to $0.24 per kilowatt-hour, we'd have reached parity on a cost-per-mile basis between electrons and dinosaurs.
p.s. keep in mind they are using 31 MPG from Volt to compare the costs... if they used >50% more efficient Prius, it would be very hard to get such cheap electricity because you would spend more than baseline and your costs would go up.

When they plug in the hybrids into the wall the power company has to burn coal to supply that electricity so instead of making co2 at the exhaust tip they are making it at the chimney. Yay green.

The best place for electric cars is Quebec. You get charged around 5.45¢/kWh
Got to love Hydro electricity. We just need more Nuclear power plants (way more clean).

31 cents per kwh? Holy crap. I thought mine was expensive at 15 cents per kwh. So if 24 cents is the magic number, then at 15 cents I'd be in the zone...until PA rate caps expire in January.

sorry, that's a stupid argument....and its been rebuked many times....look it up...even if the electricity is generated via coal its STILL way way way cleaner than the equivalent ICE tail pipe emissions.

From a pure emissions perspective, the EV movement is just silly until electric grid energy production moves away from coal.

insideline is based on socal right? That electric chart doesnt show anything higher than 20 in California...
anyways, the good news is that by 2020, PGE in california will have 40% of its energy made by alternative sources (wind, solar, and wave)

And again, 24c is breaking point for Volt which gets 31MPG... with Prius and 45-50 MPG, you would need to pay less than 15-18c just to break even, forgetting how much extra you paid for the car.

But for all we know the Plug in Prius will go further on a Kwh than the Volt does.
Using a Kill-a-Watt, I measured the total consumption in that time of 3.66 kWh. My electric cost is 8.8 cents per kWh so that charge cost me a total of 32 cents. Considering that the estimated charge time for the pack is 3 hours, I would expect that to be consistent night after night. Quick calculation: 14 miles of EV for 32 cents is 2.29 cents per mile. Compare that to my ’04 Prius averaging 60 mpg at $3.00 per gallon, which is 5.00 cents per mile. Compare that to a family sedan averaging 30 MPG and a cost per mile of 10.00 cents.
@ 31 cents per Kwh it would cost 8 cents per mile. Still seems awfully high for electric...I would go solar if I lived there.
14 miles on 3.66 Kwh = 3.8 miles per Kwh in the Prius
100 miles on 39 Kwh = 2.56 miles per Kwh in the Volt.
Unofficial of course, but that is a significant difference in efficiency. However, I would imagine that Inside Line drove the Volt hard, given the 31 MPG average, whereas all of the other reports I've been reading about the Volt have stated 38 MPG consistently.

most mags got mid 30's.... few got mid 20s.
I also wonder at miles per KWh rating basically (or KWh per 100 km), it will sure be very different between different manufacturers, just like different cars get different mpg.
