Follow our national drive for greener fleets
At ComEd, our commitment to responsible environmental stewardship is exemplified by our large fleet of alternative-fuel vehicles – a fleet ranked in a 2009 environmental report by GreenBiz.com as the 7th largest green fleet in the U.S.
Currently operating a fleet of more than 2,100 alternative-fuel vehicles means 63 percent of the ComEd fleet uses a fuel source other than straight petroleum. Compared to a non-green fleet, this reduces carbon dioxide emissions by more than 4,200 metric tons annually – or the equivalent of removing about 1,300 cars (or 400 bucket trucks) from the road for a full year.
- Alternative-Fuel Vehicle – Any vehicle fully or partly powered by an energy source other than 100% petroleum.
- Electric Vehicle (EV) – One category of alternative-fuel vehicles powered fully or partly by an electric motor with an onboard battery. These vehicles include Hybrids and Plug-in Hybrid EVs.
- Hybrid – Any vehicle with wheels driven by a combination of a gasoline/diesel engine and an electric motor with an onboard battery. The battery is typically recharged by the gasoline engine and regenerative braking. (Examples: Toyota Prius, Ford Escape.)
- Plug-in Hybrid Electric Vehicle (PHEV) – A hybrid electric vehicle with the additional capability of being plugged in to charge the onboard battery. PHEVs are currently not available from major vehicle manufacturers, and require a third-party retrofit.
- Extended Range Electric Vehicle (EREV) – An electric vehicle in which the wheels are driven solely by the electric motor, with a small gasoline engine to recharge the batteries. These vehicles also have a plug and larger battery for greater all-electric driving range. (Example: Chevrolet Volt due in 2010)
Exelon 2020. ComEd's Green Fleet is one of many environmental initiatives that support Exelon 2020, a comprehensive strategy to reduce greenhouse gas emissions.
