Carbon Reduction of Plug-in Hybrid Electric Vehicles
Estimates from the GREET model (see Argonne National Laboratory's information on GREET) show that passenger car PHEV10s produce about 29% fewer carbon emissions than a conventional vehicle, when plugged into an outlet connected to the typical U.S. grid. Even when PHEV10s are charged using power generated completely from coal, carbon emissions are about 25% less than those of a conventional vehicle. The use of light truck PHEV10s reduces emissions by 28% when charged on a typical grid and 23% when charged on power generated from coal. The carbon reductions are greater as the length the vehicle can travel on electricity increases.
