[Green Car Congress] According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Plug-in hybrids (PHEVs), either with a 30- or 60-km range, when powered by natural gas electricity, have the second lowest average emissions. Both BEVs and PHEVs provide large (more than 20%) emissions reductions compared to conventional gasoline, but none of them is a dominant strategy when compared to gasoline hybrid electric vehicles (HEVs), the team found…
