The other thing about plug-in hybrids is are they really all that green. What if you have to have a coal-fired power plant generate the electricity for your plug-in hybrid.
Good question.
Check out teslamotors.com for some info on that. IIRC (it does get complex), they claim that with their fully electric car (high efficiency - low drag, fairly light weight, no ICE to carry and they use expensive lightweight Lithium batteries), that the Tesla is net positive, even on coal.
Plug-in Hybrids are at a disadvantage, drag around the engine, can't afford lightweight batteries *and* and ICE in a typical car. So, (again IIRC) the plug-in hybrid was maybe marginally better - but I think it was actually worse on coal. Remember, coal plants don't have catalytic converters, and you waste energy in transfer, charge and discharging batteries.
But, on the news blips, they just say - ' Gets 100 MPG!!!!'
