Green Options

Recently, I discussed the interaction between clean energy and the future of plug-in hybrid electric vehicles (PHEVs). The study cited makes it clear that unless we clean up power production, there isn’t much point in moving to PHEVs from regular, old hybrids (HEVs).

Interestingly enough, MIT has just come out with a new study, profiled by Green Car Congress, which studies all sorts of vehicle options and how each vehicle will perform in well-to-wheel greenhouse-gas (GHG) emissions. This study was done particularly on HEVs, PHEVs, battery electric vehicles (BEVs), and fuel-cell vehicles (FCVs). The MIT researchers came to the conclusion that ultimately, electric propulsion in automobiles could eliminate our dependence on petroleum, which to me sounds like an exciting prospect, regardless of GHG emissions.

French analysts have concluded that the wild popularity of gasoline-hybrid electric vehicles in the United States could potentially hinder development of more sustainable and advanced green vehicles:

Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France. They suggest that the adoption of HEVs might even slow development of more sustainable fuel-cell powered electric vehicles.

The researchers go on to argue that the “misinformed craze” for hybrids in the U.S. is creating a situation where every manufacturer must include hybrid technology in their portfolio in order to stay afloat:
