Options for Alternative Fuels and Advanced Vehicles in Greensburg, Kansas
5/1/2008
After a devastating tornado that destroyed the town of Greensburg, Kansas in May 2007, plans were developed to rebuild the town as a sustainable community. This report focuses on outlining key success factors of infrastructure, alternative vehicles, and alternative and renewable fuels as part of an integrated energy strategy.

Clean Cities Annual Metrics Report 2006
7/1/2007
Clean Cities coordinators submit an annual report of their activities and accomplishments for the previous calendar year. Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions as well as data about sales of alternative fuel blends, deployment of alternative fuel vehicles, hybrid electric vehicles, idle reduction initiatives, and fuel economy activities. NREL analyzes the data and translates them into gasoline reduction impacts.
Survey results indicate that about 375 million gallons of gasoline were displaced through Clean Citiew efforts in 2006, 50 percent more than in 2005. Alternative fuel vehicles accounted for 71 percent of the reduction. Biofuels (ethanol and biodiesel) used in AFVs displaced 128 million gallons, 34 percent of the total 375 million.

The Harmful Effects of Vehicle Exhaust: A Case for Policy Change
1/1/2006
Most people assume that the U.S. Environmental Protection Agency is sufficiently protecting air quality by setting limits for chemicals released from vehicles, requiring newer engines to be less polluting, and restricting levels normally found in outdoor air. While the government monitors pollutants at fixed stations, these measurements bear little resemblance to the pollutiuon you and your family experience while moving through daily life. This report examines a variety of harmful effects from air pollution, including that caused by vehicle exhaust. The report focuses on Connecticut.

Study of Exhaust Emissions from Idling Heavy-Duty Diesel Trucks and Commercially Available Idle-Reducing Devices
10/1/2002
Heavy duty diesel truck idling contributes significantly to energy consumption in the United States. The EPA initiated a study to quantify long duration idling emissions and fuel consumption rates over a two year period. It performed 42 tests on nine class-8 trucks (model years ranging from 1980s to 2001). Two of those trucks were equipped with 11 hp diesel auxiliary power units (APUs), and one was equipped with a diesel direct fired heater (DFH). The APU powers electrical accessories, heating, and air conditioning, whereas the DFH heats the cab in lieu of truck idling. Results indicate that use of an APU can reduce idling fuel consumption by 50 to 80% and reduce NOx by 89 to 94%. The use of a DFH can reduce fuel consumption by 94 to 96% and reduce NOx by 99%.
