About those green tech cars
...There is much more. The electrics start out behind because the carbon expended in the manufacturing process is over twice as much as that expended in manufacturing a conventional car. When you consider their limited range there is little reason to own one. I suspect the green vision is that the power will come from solar or wind to recharge the batteries, but those sources are too undependable to count on.
If a typical electric car is driven 50,000 miles over its lifetime, the huge initial emissions from its manufacture means the car will actually have put more carbon-dioxide in the atmosphere than a similar-size gasoline-powered car driven the same number of miles. Similarly, if the energy used to recharge the electric car comes mostly from coal-fired power plants, it will be responsible for the emission of almost 15 ounces of carbon-dioxide for every one of the 50,000 miles it is driven—three ounces more than a similar gas-powered car.
