重点在这里“ In 2007, a report commissioned by an auto industry trade group
insisted that when you factor in the waste generated during production, the
notoriously gas-guzzling Hummer is actually greener than the Prius”
*****************************
Does hybrid car production waste offset hybrid benefits?
The hybrid car has been touted as the green savior of the automobile
industry. A decade after the Toyota Prius debuted worldwide, issues like
climate change and energy security have helped push the popular hybrid's
sales numbers past the two million mark -- nearly half of them sold in North
America [source: Autoblog].
Americans don't buy the Prius for its style or speed. They buy it to save
money on gas and to shrink their carbon footprint. In most American cities,
the personal automobile is the largest overall polluter, spewing millions of
pounds of greenhouse gases like carbon dioxide, nitrous oxide, carbon
monoxide and sulfur oxide into the atmosphere and into our lungs [source:
EPA]. Eco-conscious consumers see the Prius and other hybrids as an
investment in the environment and in our collective future.
But are hybrids really as green as they seem? How much is marketing hype and
how much is scientific fact? Because hybrids have a second electric motor,
they burn less fuel than conventional cars and emit lower levels of
greenhouse gases during operation. That's great, but what about the hybrid
manufacturing process? In 2007, a report commissioned by an auto industry
trade group insisted that when you factor in the waste generated during
production, the notoriously gas-guzzling Hummer is actually greener than the
Prius [source: Slashdot]. While this report was largely discredited by
environmental groups, it did raise an important question: does the pollution
created during hybrid production offset the benefits of "green" driving?
The answer might surprise you. According to an in-depth study by the U.S.
Department of Energy's Argonne National Laboratory, hybrid cars do, in fact,
require more energy to produce than conventional cars, emitting more
greenhouse gases and burning more fossil fuels during the manufacturing
process. The production of hybrid batteries, in particular, requires much
more energy than producing a standard car battery and results in higher
emission levels of gases like sulfur oxide [source: Burnham et al].
But do the environmental impacts of hybrid vehicle production outweigh the
long-term benefits of driving a cleaner running automobile? That answer is a
resounding "no." If you drive both a conventional and hybrid car for 160,
000 miles (257,495 kilometers), the conventional vehicle requires far more
energy to operate and emits far more greenhouse gases over its lifetime,
significantly canceling out any imbalance during the production stage [
source: Burnham et al].
Keep reading as we break down the statistics for both hybrid production
emissions and hybrid driving emissions and learn what "green" really means.

咱德州反正年检不查emission,17刀查个safety了事。
老夫golf连整套emission system都卸掉了,屁事没有。
