When you get such an "interesting" position piece stating a conclusion
that seems suspicious, go to the webpage and do some detective work.
This company seems to be a consumer survey company hired by automotive
manufacturers. As such, I personally wouldn't trust their message one
way or another. We're supposed to be researchers/educators here at UF.
Let's look at the topic of embodied (sp?) energy and do an internet
search on battery technology. From my limited knowledge I can say that:
1. Recycle rates for batteries are very high.
2. Energy costs for different modes of shipping vary widely with
shipping by sea being by far the most efficient. The second article
makes quite a big deal about shipping nickel all over the world by sea.
3. Sudbury was an environmental mess. It would be interesting to see
if the nickel produced there now is produced in the same environmentally
unsound manner or if things aren't drastically different in the positive

Subject: Prius Outdoes Hummer in Environmental Damage
The first link is to a recent study that calculates the energy and
dollar footprint for contemporary automobiles. The study has
provoked controversy with its conclusion that the Toyota Prius, a
hybrid that gets 45-50 mpg, is more energy intensive per mile than
the infamous gas hogging Hummer.
The second link is a short editorial that goes into some detail as
to why the Prius is so energy intensive. I personally know of a
Prius that is going strong at 150,000 miles, so there definitely
is room to quibble about the assumed life span. Assuming that both
the Hummer and Prius go for 300,000 miles, the Prius would come
out on top using their methodology (but not by all that much). Any
