Transportation and Transit. Hybrid Buses Yield Lower Emissions and Greater Fuel Efficiency.
A recent study by the National Renewable Energy Laboratory of the U.S. Department of Energy's found that hybrid buses operate with lower emissions and greater fuel efficiency than conventional diesel buses.
 
The study evaluated the performance of 10 prototype diesel hybrid-electric buses in the New York City Transit fleet. Hybrid buses showed 10 percent higher fuel economy and in-service fuel economy. According to chassis dynamometer emissions 36 percent lower oxides of nitrogen and 50 percent lower particulate matter emissions than diesel buses. New York City Transit has awarded contracts for an additional 125 hybrid buses in 2002 and 200 hybrid buses in 2003.
 
A two page summary of the report may be found at: http://www.afdc.doe.gov/pdfs/diesel_hybrid.pdf. (94)
