Alternative Fuel Vehicles

Natural Gas

Using compressed natural gas (CNG) to fuel our vehicles produces significantly less harmful emissions compared to diesel and gasoline, and Texas has plenty of natural gas.  Plus, its use keeps profits in America, not overseas.  Many of the City’s fleet of sedans, pickups, and large sanitation trucks operate on natural gas.


Biodiesel is a renewable fuel produced from vegetable oils and animal fats.  Either pure or petroleum blended biodiesel can fuel diesel vehicles, providing energy security while lowering emissions.  Biodiesel is nontoxic, biodegradable, and can be made from waste material that may otherwise end up in a landfill or waterway.  You can help by saving your old cooking oil and grease and taking it to one of Sanitation’s transfer stations or an oil and grease recycling drop off center.  Visit to find out more!


Ethanol is a renewable fuel made from various plant materials, which collectively are called “biomass.”  All gasoline contains a minimum of 10% ethanol in a blend to oxygenate the fuel and reduce air pollution.  Ethanol is also increasingly available in E85, an alternative fuel that can be used in flexible fuel vehicles.


Propane, or liquefied petroleum gas, is non-toxic and presents no threat to soil, surface water, or groundwater.  Traditional uses of propane include home heating, cooking, and powering farm equipment.  Some industrial lawn mowers and large pickup trucks are now manufactured to operate on propane.  Propane is now the third most used vehicle fuel behind gasoline and diesel.
