Debunking "green" vehicles
- Besides the obvious problems with any cars, does anyone have recommended
studies/resources analyzing the various "green" vehicles in terms of life
cycle analysis (total carbon emissions, embedded and operating energy,
toxic emissions associated with manufacture and operation, etc.)?
E.g., this would include electric cars (including hybrids), hydrogen
fuel-cell cars, etc.

Essentially, hybrids take slightly more energy and cause slightly more
emissions to manufacture than do conventional cars, and electric
considerably more. Their emissions after manufacture then depend on
how much they're driven, and for the electrics, how the electricity is
got. If you electric car gets power from a coal-fired station, it's
basically the same as driving a regular car - it's just that the
emissions are all wherever the power station is rather than out of
your pipe. An electric vehicle powered by renewable energy, however,
would have a relatively small impact while in use.
In the end, using a tonne of metal to move one person is never going
to very efficient...
I'm ashamed to say I got my driver's licence today. Doesn't mean I'll
be driving, though.
I think cars are like firearms: everyone should know how to use them
safely, but that does not mean everyone should own one, still less
that everyone should use them every day.
