Read all about it A million thanks to Frenchie for this one... Add this issue to the long list of the "things grass eaters do to save the planet that actually hurt the planet more" category. It turns out the energy required to manufacture a Toyota Prius hybrid far exceeds not only the energy required to manufacture a Hummer (by quite a lot), but the overall energy 'footprint' (to borrow from the grasseating lexicon) to manufacture and drive said Prius 100,000 miles exceeds that of a Hummer when driven 300,000 miles. I just love liberals; the Vulcans would never visit earth while Libs are in charge, that's for sure; they couldn't handle the illogic.
