I agree that if people think a "zero-emissions" vehicle is actually
non-polluting, they are extremely ignorant of where electricity comes
being said, I would have a hard time believing that those numbers are
correct. It could be possible looking at strictly the coal to produce
electricity to move the car the same amount as a gallon of
However, how much energy is used to truck the gas from the refinery
to the gas station? How much to refine that gallon of gas from oil?
How much to transport the oil from the rig...how much to power the rig...how
much to build the rig...to power the engineering and manufacturers building...to
drive to work to design a rig...etc...etc...
actual math is very complex...so much so that I doubt it could actually be
think the hope is that with more electric vehicles, we are dependent on
electricity, of which we have a lot of resource in the US, and become less
dependent on oil, of which we don't have a lot of local

renewable energy in the US.
Further, electricity is cheaper than gas, and will ultimately help
Eventually we would hope that solar panels and wind farms would power
all our electric vehicles. I guess we first need solar panel and wind
turbine manufacturers to run 100% on solar or wind power themselves, but baby
steps are good.
fact is economic demand will push us to a renewable and clean energy policy far
before moral outrage will. Electric vehicles will create an economic
A letter to the editor in today's
Chronicle quotes "a recent article in National Geographic that with
a coal-fired energy source, a zero emissions electric vehicle actually is
responsible for more than twice the amount of carbon dioxide as produced by a
conventionally powered gasoline vehicle."
If this is so, do we still want to drive these "clean"
vehicles? Here is a link to the article (scroll down to the 5th letter "A
Fly in the Ointment")
