#12 of 13 hyrids are cleanest vehicles except pure electric by eaa Mar 31, 2006 (3:30 pm)
It has been studied and hybrid make less emissions than any vehicle except pure electric s. The electric comes from power plants that are regulated and have scrubbers on them to meet certain standards. 50% of US power comes from coal fired power, 17% from scary nuclear. As was noted in another response hybrids make most of their power from coasting and regen braking, power lost on regular vehicles. Hybrids are very clean. Most are also smaller and lighter and more aerodynamic like the Prius at .25 CD. Replies to this message: stevedebi (Mar 31, 2006 4:00 pm)

Replying to: eaa (Mar 31, 2006 3:30 pm) "As was noted in another response hybrids make most of their power from coasting and regen braking, power lost on regular vehicles." Unfortunately not true. Hybrids simply recapture energy that was first expended (in one form or another) by the ICE. Either the battery was originally charged by the ICE, or the ICE contributed to the speed being used to be converted to regenerative braking. And of course the ICE created the speed used for "coasting". No one has yet created the engine that will "make" power, a.k.a. "perpetual motion machine".
