Today, there are many different types of fuels being used in vehicles as "alternatives" to gasoline or diesel. In most instances, the alternative fuel is less polluting, resulting in fewer harmful emissions in the air and a lower negative impact on human health. Many cities and companies across the nation, such as Clean Cities, have adopted programs to use alternative fuels in their fleets. These same entities are encouraging efforts to provide the fueling infrastructure necessary to operate alternatively fueled vehicles.

Battery (Electric Vehicles)
Electric vehicle batteries are primarily charged from electricity that is produced at a central power plant, with its associated emissions. Electric vehicles produce no tailpipe emissions and are generally more efficient than conventional vehicles.
Battery and Gasoline (Hybrid Electric Vehicles)
A hybrid electric vehicle (HEV) combines the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle, resulting in twice the fuel economy of conventional vehicles. Several automakers currently sell vehicles with this technology.
Biofuels
Biofuels are liquid fuels made from renewable resources. Corn ethanol, such as E-85, and soy-based biodiesel are the most commonly used.
Compressed Natural Gas
The interest for compressed natural gas as an alternative fuel stems mainly from its relatively clean burning qualities, its domestic resource base, and its commercial availability to end-users. Natural gas is primarily produced from gas wells or in conjunction with crude oil production. Compressed natural gas may also be generated from renewable sources using livestock waste or other organic waste through a process called anaerobic digestion.
Hydrogen
Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels. Other uses for hydrogen include alternative vehicle fuel via a hydrogen fuel cell battery. However, there is a high cost of fuel cells and lack of hydrogen fueling stations in the United States.
Methanol
Methanol is another alcohol-based fuel. Today most of the world's methanol is produced by a process using natural gas as a feedstock. The majority of methanol currently used as transportation fuel is M-85.
Propane (LPG)
Liquefied petroleum gas (LPG) in the U.S. consists mainly of propane, but may also include propylene, butane, and butylene in various mixtures. LPG is produced as a by-product of natural gas processing and petroleum refining and is in gas form at normal temperatures and pressures. Most of the LPG used in the U.S. is produced domestically. Propane has been used as a transportation fuel around the world for more than 60 years. Missouri has approximately 320 propane fueling sites.
Solar
Solar energy is derived from the sun. In order to collect this energy and use it to fuel a vehicle, photovoltaic cells are used. Much research has gone into evaluating how solar energy may be used to power vehicles, however the long-term possibility of operating a vehicle on solar power, alone, will depend on new technology development and is now used only to power certain auxiliary systems in the vehicle.
