About those green tech cars

...
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.
...
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.
