Companies do themselves no favours claiming that things are emission free when all they are doing is shifting the energy process hence pollution somewhere else.
If said companies were honest, they'd mention that the pollution such cars produce even from a coal plant is there, but still less than a comparable gasoline powered car. Fortunately, many of them, like AC Propulsion, or Commuter Cars are fairly honest about this. On the other extreme, you had General Motors, Chrysler, and Ford funding false studies with grossly inaccurate figures claiming the electric cars made much more pollution than comparable gas cars when the emissions and batteries were counted. These false studies were off by factors of thousands, but were used as a smear campaign to paint a negative picture of the technology.
What I need to know is how much energy(usually electricity) is used to make this car's 'fuel', and how much energy it takes to recycle it. This will let one calculate the pollution associated with its use.
The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson
