Replying to: mo460 (Dec 10, 2005 4:04 pm) As has been stated in other posts, hybrids don't plug into the electric grid to get recharged. Even if they did, here in Southern California the electricity generators are either natural-gas fired, nuclear, or hydroelectric. Exhaust emissions from these sources of electricity as compared to exhaust emissions of the current crop of hybrids would seem to be even.   Now, where electricity generators are fuel-oil fired or even coal fired, it would be obvious to anybody that the comparison of exhaust emissions between such powerplants and the current crop of hybrids is a win for the hybrids.

There is a controversy on right now as to if it will stay open... Replies to this message: robertsmx (Dec 13, 2005 9:27 am)

Replying to: stevedebi (Dec 12, 2005 1:47 pm) As I pointed out earlier, a plug-in vehicle will indeed draw energy from an electric power plant. But so will production and delivery of additional gallons of petroleum that a non-hybrid would need.
#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".
