Fuels & Vehicles

As a Clean Cities coalition, we promote all alternative fuels – electrification, biodiesel, natural gas, renewable fuels, biofuels, natural gas, and more – that help to reduce transportation emissions.

Promoting Alternative Fuels and Vehicles

Advanced vehicle technologies, electric vehicles, alternative fuels and anti-idling help to reduce emissions, improving local air quality and helping to reduce our nation’s dependance on foreign oil.

Many of these emissions-reducing fuels and technologies are featured below.


Biodiesel a diesel substitute fuel made from biomass, which means that it is inherently renewable and it, in itself, contributes nothing to carbon-dioxide loading of the atmosphere.

Ethanol burns cleaner than gasoline; it is a completely renewable and domestic fuel that enhances the economy and energy independence of of the nation.

Natural Gas

Compressed natural gas (CNG) is the same natural gas that is used in home heating, except that it has been compressed to 3600 psi in a high-pressure tank for use in a vehicle.

Liquefied petroleum gas (LPG) is basically the same type of gas that is used in home barbeques. For automotive applications, it is a mixture of propane gas and butane gas.

Hydrogen will play an important role in developing sustainable transportation in the U.S., because in the future it may be produced in virtually unlimited quantities using renewable resources.

Electric Vehicles

Electric vehicles (EVs) are propelled by an electric motor (or motors) powered by rechargeable battery packs. Electric motors have several advantages over internal combustion engines (ICEs)

Hybrid Vehicles

Hybrid-electric vehicles combine the benefits of gasoline engines and electric motors and can be configured to improve fuel economy or increase power.

Fuel Conservation

Idle reduction technology allows engine operators to refrain from long-duration idling of the main propulsion engine by using an alternative technology.
