BOSTONMassachusetts is seeking $6.5 million in stimulus funding from the federal Department of Energy to spur the use of hybrid and alternative fuel vehicles by municipalities, private companies, and government agencies, according to the Boston Globe.

"Our single biggest greenhouse gas emitter is transportation," said Philip Giudice, commissioner of the state Department of Energy Resources, as reported by the Globe. The money would be used to purchase about 315 vehicles, including buses powered by compressed natural gas and hybrid trucks and taxis. Though the emissions reductions are not guaranteed, Giudice said he has "high expectations."

Several communities and agencies have already indicated they want to upgrade their vehicle fleets. Boston city officials want to build five electric vehicle charging stations and add plug-in hybrids to their fleet, according to the Globe.
