A controversial 2006 study by CNW Marketing Research, Inc. calculated the overall energy cost of a Prius at US$3.25 per mile ($2.02/km) and a Chevrolet Tahoe SUV at US$2.94 per mile ($1.83/km). It concluded that 2005 hybrids cost "significantly more in overall energy costs than conventional Internal Combustion Engine [sic] (ICE) vehicles." David Friedman of the Union of Concerned Scientists commented that the study "has been completely contradicted by studies from MIT, Argonne National Laboratory, and Carnegie Mellon's Lifecycle Assessment Group." An article on the Better World Club website investigates the source of the statement "a Hummer is more energy efficient over its lifetime than a Prius", which it characterizes as an urban legend. It suggests that the source may be the CNW "Dust to dust" study, or follow-up articles by James L. Martin or Chris Demorro, and goes on to challenge some of the assumptions made in the study. A critique of the 2007 version of the CNW report by the Pacific Institute concluded that "closer inspection suggests that the report's conclusions rely on faulty methods of analysis, untenable assumptions, selective use and presentation of data, and a complete lack of peer review. Even the most cursory look reveals serious biases and flaws."
WTF are you talking about? I don't pull shit out from thin air. I do research. I read, post my opinion, talk about the facts then that's it.
half the people who drive them think they are saving the world though, it would be a great car to have if you dont want to spend alot of money on gas, but its not saving the earth like most prius owners think.
