Thank You!
Not done by me:
Chevy Volt at the invitation of General Motors.
For four days in a row, the fully charged battery lasted only 25 miles
before the Volt switched to the reserve gasoline engine.
Eric calculated the car got 30 mpg including the 25 miles it ran on the
battery. So, the range including the 9 gallon gas tank and the 16 kwh
battery is approximately 270 miles. It will take you 4 1/2 hours to
drive 270 miles at 60 mph. Then add 10 hours to charge the battery and
you have a total trip time of 14.5 hours. In a typical road trip your
average speed (including charging time) would be 20 mph.
According to General Motors, the Volt battery holds 16 kwh of
electricity. It takes a full 10 hours to charge a drained battery.
The cost for the electricity to charge the Volt is never mentioned so I
looked up what I pay for electricity.
I pay approximately (it varies with amount used and the seasons) $1.16
per kwh.
16 kwh x $1.16 per kwh = $18.56 to charge the battery.
$18.56 per charge divided by 25 miles = $0.74 per mile to operate the
Volt using the battery.
Compare this to a similar size car with a gasoline engine only that
gets 32 mpg.
$3.19 per gallon divided by 32 mpg = $0.10 per mile.
$3.75 per gallon divided by 32 mpg = $0.12 per mile.
The gasoline powered car cost about $15,000 while the Volt costs
$46,000.
So Obama wants us to pay 3 times as much for a car that costs more that
7 times as much to run and takes 3 times as long to drive across country.
REALLY? I say "drill here - drill now". This is nuts, but people have bought them.

um, average price per kilowatt hour in US: somewhere between 0.11 and 0.12.
Mine: 0.28how does that effect both of your calculations? don't care much for Obama but....i think Tonga has the worst rates in the world at over $0.50.

Oilspot,
SolbergFanBoi's math is a little fuzzy you might want to recheck it.
I pay .14 per kwh so that meens it cost $2.25 to charge a battery not $18.56 to charge the battery.
So $2.24 per charge devided by 25 miles is $.089 per mile; not $0.74 per mile.
That less than 9 cents per mile by my math, but I dont use that GWB fuzzy math.
would you like me to continune to debunk the rest of the math?
Ps. the average daily comute in the US is 27 miles. 27x.089 =$2.41

In another few generations, when hybrids like the Volt are standard at most homes, we'll have a whole new group of "wild" teens figuring out to hack into the computer, force electric power to standby, and increase the pulse width to the injectors to lay some rubber (just like great grandpa did with two four barrels attached to most anything). The attraction of young males to increased velocity will never go out of vogue. But going wading with a big battery Rover hybrid might be real fun in the salt marsh.... they found the truck with just the roof rack sticking up out of the mud hole.

If we all gave in and just road bicycles everywhere the clowns in Washington would find a way to create a "carbon tax" for the exhaust coming out your a$$...
