We’re on GreenMountain 100% wind generated electricity (and don’t tell me they don’t have enough wind generators in Texas for their customers – they’re busy right now building a wind farm in an extremely windy place in an adjacent county).
But even if an EV were powered by dirty coal-generated electricity, it only involves about two-thirds the pollution of an ICE car, and the pollution can be controlled at the power plant. I knew some people in an EV conversion club in IL (The Fox Valley Electric Vehicle Association), and they gave me some lit on it, plus a book, “Why Wait for Detroit?”
Re my calculation, I was comparing it to a 2010 Ford Focus. My husband really wanted a Ford Taurus, but not the ones built after 2008, but we couldn’t find any 2007-2008 models for sale in our area. And he didn’t like the Focus bec he felt squashed, so we probably would have actually gone for a bigger gas guzzler, rather than a smaller economy car. He totally dismissed the Cobalt and Aveo without even test-driving them.
The Volt is roomy enough and he likes the way it drives. You know how men are about cars - picky, picky picky
Here are my calculations (which may or may not be very accurate):
PRICE & MAINTENANCE:
Car price: Volt (42,000 + 2625 tax) - 1200 trade-in - 7400 tax rebate = $36,025 - 17,000 selling price in 7 years = 19,025
Other car at 24 mpg city (15,000 + 938 tax - 1200 trade-in + 3000 additional auto repairs in 7 years) = 17,738 - 5000 selling price in 7 years = 12,738
COST DIFFERENCE after 7 years:
$6288 more for the Volt
FUEL COSTS:
A. DRIVING UNDER 36 MILES/DAY: At 12.7 cents per KWH, a 60% charge of the 16 KWH battery capacity (= 9.6 KWH – it’s buffered 20% on the upper and lower levels), which gets a 40 mile range, that comes to about $1.22 per 40 miles (I figured high at $1.30 per 36 miles – figuring low on the range due to AC and other factors). At 5,000 miles per year being driven less than 36 miles in a day, that comes to $179. Other car (at 24 mpg city) 5,000 miles/24 mi = 208 gallons x $5 per gallon (which is likely under what the 7 year average will be) = $1040/year
DIFFERENCE PER YEAR on Under 36 mile/day driving: $861 savings with Volt x 7 years = $6024 savings
B. DRIVING ABOVE 36 MILES/DAY:
Figuring high at an extra 1000 miles per year for miles driven above 36 miles in a day (like a 300 mile trip), at 40 mpg highway for Volt = $125 per year. For other car at 30 mpg highway = $165 per year.
DIFFERENCE PER YEAR on over 36 miles per day: $40 savings with Volt x 7 years = $280.
**A + B: total driving savings with Volt over 7 years: $6304
PRICE COST DIFFERENCE (from above): $6288**
TOTAL DIFFERENCE (cost, driving): In 7 years the Volt about breaks even, saving $17, but thereafter goes on to save $900 per year. Those savings could then be applied for the big upcoming expense of new batteries in, say, 70,000 to 100,000 miles (in 12 to 17 years). Not to mention this is a really fancy, hi-tech car that would be a real guy-catcher; hubby is REALLY sold on it now that he’s seen all the fancy stuff – while I wouldn’t mind if you had to hand crank the windows.
I realize there may be hidden expenses I’m not factoring in; but there may also be hidden savings, as well. When we got our SunFrost frig in 1991 (uses one-tenth energy of conventional frig, actually 1/12 of our old clonker frig at the time), we also found out that veggies hardly spoiled at all, so there was a lot of extra savings there, and the $2700 frig (incl shipping from Arcata, CA) not only went on to save the difference, but to actually pay for itself in relative savings over the years.
And we haven’t even factored in the lives saved and miscarriages prevented…
