Researchers at MIT and the Ford Motor Company have found that depending on the location, lightweight conventional vehicles could have a lower lifecycle greenhouse gas impact than electric vehicles, at least in the near term. Lifecycle GHG emissions per km for different powertrain types (ICEV, LW-ICEV HEV, PHEV, and BEV) in selected counties.

MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. emissions are reduced by around 25% relative to the use of gasoline for the same engine efficiency.

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours. The results are less clear in Dallas and Houston.

The MIT Technology Review reports plug-in hybrids a big 2006 energy story: "The plug-in hybrid-vehicle era begins. This allows the cars, which typically rely on the electric power only for short bursts or to assist the onboard gasoline engine, to run on electricity alone for short trips. See "GM's Plug-In Hybrid.")

PHEVLERs are defined as PHEVs with sufficient battery capacity for all electric driving of twice the average daily distance. [ Electric fuel cost is a fraction of gasoline or diesel fossil fuel cost, even at a time when petroleum prices are temporarily reduced due to geopolitical manipulations and manufacturing costs.
