Plug-in hybrid: true comparison?
The current US average price for a 1 kW collector is about $5,450. If your figures and calcs are correct, that means investing probably $7,000 or more to install the collector and charging equipment for a tiny car that only travels near home and only 30 miles per day. And only when the sun shines.
Still needs work, unfortunately.
Plug-in -vs- buying gas - video comparison
for a comparison between the hassle of putting gas into a Prius versus plugging in an EV at home.
A good blog on the subject
Essentially the point is that to have a car that is a good plug in EV you need a full electrical drivetrain and battery pack. To have a car that can do long road trips when the batteries die you need a full gasoline engine drive train. The weight of each compromises the range and efficiency of the other. The complexity of having two complete drivetrains is a potential maintenance nightmare. And, of course, with two drive trains there is little space for people and luggage.
You would be better off with a pure EV like a Tesla that can go 200 miles on a charge, and have a second car (diesel?) for long trips. Or even cheaper, rent a car for long trips. The few long trips most people go on, it is cheaper to rent.
PV Solar Panels to Power EV car
I agree with the poster that said that installing a 7,000 solar panel to power a car "needs work."
However, I have an 8Kw solar system on my house and I am better than energy neutral (meaning I generate more power than I use).
In conjunction with eliminating my home bills and still being able to completely power my Tesla (perhaps the upcoming Whitestar, but if I can, the roadster), the 40K spent on the solar is pretty good (with the power company paying half and a 1k state tax credit and a 2k federal tax credit).
However, the investment is likely still to high for the average consumer (even though they buy 50k SUVs) and it does need a lot of roof space in a good open area (I am in AZ).
Another option is Ethanol.
Another option is Ethanol. But NOT corn based ethanol.
the USA is trying to produce ethanol from corn. But from seed to gas tank, it takes 1 gallon of petrolium to produce 1.3 gallons of ethanol.
Brazil is producing suger cane ethanol with 8 gallons of ethanol produced from each gallon of fuel used to produce the ethanol.
but suger cane does not grow well in Montana.
BUT... cellulose based ethanol can be produced from sawgrass that grows from Dakota to Texa. Sawgrass based ethanol produces 10 gallons of ethanol from each gallon of fuel used to produce it.
So why are we using corn? Because Con-Agra, Agway, Monsanto, el al paid our government to use corn. Regardless of the science.
I donít believe your
I donít believe your 1.35 lb of CO2 /kw-hr of electricity. You should probably clarify/support.
Also, you conveniently miss all of the upstream CO2 required for the pumping, transportation, and refining of gasoline.
Youíll find that than an EV (or Prius in EV mode) can go farther on the electricity required to refine a gallon of gasoline (ignoring pumping and transportation energy) than most cars can go on the gallon of gasoline.
