Division for Air Quality
Hybrid Electric Vehicles

The Division for Air Quality incorporated nine hybrid electric vehicles (HEVs) into its fleet.  The Energy and Environment Cabinet (EEC) and Division of Waste Management have also added hybrids to their fleet.  EEC estimates over $3,000 per year in fuel costs have been saved per vehicle purchased.

Our education and outreach program offers HEV education for schools or events.  If you would like to have a HEV and educational program come to your school or event, you may contact our education coordinator Roberta Burnes.

HEVs are an innovative technology that incorporates two sources of power – a gasoline engine and an electric (battery) powered motor.  These two power sources work in tandem, increasing fuel economy and reducing air emissions.

How do HEVs Work?

Hybrid electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power or additional auxiliary power for electronic devices and power tools. For more information on how HEVs work go to this Web site:

This is a diagram on how a Hybrid vehicle operates.

How do HEVs reduce air emissions?

First, hybrids reduce air emissions by increasing fuel economy.  Second, many hybrids are designed to meet more stringent emissions standards, such as SULEV (Super Ultra Low Emissions Vehicle) and PZEV (Partial Zero Emissions Vehicle) standards set by the California Air Resources Board.
