Volt looks like a good car for a lot of the general population. A little high on price especially with the economy the way it is these days. Someone commented that it is a lemon as far as pollution is concerned. "Trading pollution from burning gas for making electricity". It would appear to be true but if you take gas burned in a year and the pollution to refine the oil and transport it I think this may be a step towards less pollution. Think about it. If an average person burns 1000 gallons of gasoline a year and you change to a Volt and use the 70% value, that is 700 gallons less per year that is used. The pollution associated with that 700 gallons would have to include drilling the oil, pumping the oil, transporting the oil, refining the oil, the transportation by a tanker truck of that gas to a retailer, the leakage of fumes by that 700 gallons of gasoline, etc. Even if the average Volt user population were to only achieve 50% less fuel, that would be a significant reduction. How many kilowatts total from drill to pump does it take to make gasoline? A lot more than what the Volt needs to take a charge. A person could offset the kilowattage used to recharge the car by converting things in the house that waste electricity to something with higher efficiency. CFL bulbs, LED bulbs, HE washer and dryers, on demand water heaters, HE ground source heat pumps, low flow toilets, turn off electric devices, recycle trash, insulation, etc. We have to start somewhere and this is just the first step. Battery/power source technology will have to advance quickly and this may be the motivation to make those advances. Plus, there are at least two other car manufacturers making electric drive cars. The more manufacturers that get into the market the more likely we will see advances in technology.
