origins and history
Origins and History
  • Created by DOE to address requirements in Energy Policy Act of 1992
    • Technical, financial, and information assistance to communities with alt fuel deployment plans and to regulated fleets

Clean Cities Mission

To advance the national, economic and energy security of the US by supporting local decisions to use domestically produced non-petroleum fuels in vehicles

clean cities coalitions
Clean Cities Coalitions
  • Public-private partnerships at local, regional, or state level to speed implementation of advanced vehicles and alternative fuels
  • 87 active coalitions
clean cities technologies
Clean Cities Technologies
  • Alternative fuels (as defined by EPAct)
    • E85, CNG, biodiesel, propane, hydrogen, electricity
  • Alternative fuel blends
    • E10, B5, H-CNG
  • Energy efficiency
    • Hybrids, idle reduction, fuel economy
fuel blends
Fuel Blends
  • Low level blends of alternative fuel with conventional fuel
  • E10, B2, B5, H/CNG, for example

Fuel Economy

  • Techniques that reduce fuel consumption
    • Selecting the right vehicle for the job
    • Advanced technology – low rolling resistance tires, HEVs, proper maintenance, tire inflation, carpooling
hybrid electric vehicles hev
Hybrid Electric Vehicles (HEV)
  • Hybrids use two sources of energy – electricity (batteries) and conventional or alt fuel powered ICE

Idle Reduction

  • Techniques include on-board APUs, shorepower, truck stop electrification, truss-mounted off-board heating/cooling units
alternative fuels
Alternative Fuels


  • Alcohol-based fuel produced from starch crops or cellulosic biomass such as trees and grasses
  • High octane, often used to enhance octane properties of gasoline
  • As an alternative fuel, most commonly used in a blend of 85% ethanol and 15% gasoline (E85).
  • Flexible fuel vehicles (FFVs) and are offered by several vehicle manufacturers. See the ethanol vehicles page for more information on FFVs.


  • Widespread distribution infrastructure
  • Clean burning in natural gas vehicles
  • Most common in medium- and heavy-duty markets
  • Stored onboard a vehicle as compressed natural gas (CNG) or as liquefied natural gas (LNG) Propane:
alternative fuels11
Alternative Fuels


  • Manufactured from vegetable oils, animal fats, or recycled restaurant greases
  • Biodiesel is safe, biodegradable, and reduces serious air pollutants such as particulates, carbon monoxide, hydrocarbons, and air toxics
  • Blends of 20% biodiesel with 80% petroleum diesel (B20) can generally be used in unmodified diesel engines
  • Can be used in its pure form (B100), but it may require certain engine modifications
  • Potential issues with operation in cold weather

Propane (LPG)

  • Produces fewer vehicle tailpipe emissions than gasoline
  • Produced as a by-product of natural gas processing and crude oil refining
  • Widespread infrastructure of pipelines, processing facilities, and storage
alternative fuels12
Alternative Fuels


  • Used to power battery electric vehicles
  • Electric vehicle batteries have a limited storage capacity
  • Batteries are replenished by plugging the vehicle into an electrical source, through engine operation on gasoline, or regenerative braking


  • Emerging fuel for use in fuel cells engines for transportation
  • Can be produced from a variety of processes that range from utilizing coal feedstock to biomass or renewables
  • Demonstration projects ongoing in select areas across the US
clean cities unique assets
Clean Cities Unique Assets
  • Coordinators
    • Local champion and point of contact
    • Strong local relationships and understanding of player and issues.
  • Coalitions
    • Members are committed to the mission
    • Build bridges in the local community to mutually address barriers
  • Technical Information and Resources
    • AFDC recognized nationally and abroad as reliable sources of unbiased information
    • 4.8 million page hits (FY2005)
    • Over 76,000 documents being downloaded
  • Local Strategy to Advance a National Goal
    • Local involvement works effectively in communities
    • National leadership adds legitimacy to local activities and assists with information transfer among coalitions.
