CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said. Credit: ACS, Weis et al.

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid.

Toyota "Moves"

Plug In Partners

Toyota moves to corner the 'plug-in' market Reversing course, the Japanese automaker reveals it will make hybrid cars that can go even farther on electricity. But gasoline prices have since soared to more than $3 a gallon. A typical hybrid has a big gasoline engine and a tiny electric motor.

But when you do, your car essentially becomes an electric vehicle with a gas-tank backup. Lifetime service costs are lower for a vehicle that is mainly electric. Scientist have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner.
