* Internal Combustion Engines (Conventional Vehicles)


- Gasoline- Crude Oil


- Diesel- Crude Oil


* Internal Combustion Engines (Alternative propulsion)


- Natural gas- Underground reserves

                (Compressed Natural Gas- CNG)

                (Liquefied Natural Gas-LNG)


- Propane (Liquefied Petroleum Gas-LPG)- A by-product of petroleum refining or natural gas processing


- Ethanol (E85)- Corn, Grains, or agricultural waste (85% Ethanol + 15% gasoline)

- Hydrogen- Natural Gas, Methanol, and other energy sources. (


- Biodiesel (blend B 20, pure biodiesel B100)- Soy bean oil, waste cooking oil, animal fats, and rapeseed oil. (


* Alternative fuel vehicles (AFVs):

Alternative fuel vehicles include any dedicated, flexible-fuel, or dual-fuel vehicle designed to operate on at least one alternative fuel. Alternative fuel vehicles come in a variety of vehicle models such as sedans, pickup trucks, sport utility vehicles, vans, shuttle buses, medium-duty vehicles (such as delivery trucks), heavy-duty buses, and heavy-duty trucks.


* Alternative propulsion


- Electricity (battery operated- plug in) (


- Hybrid (IC engine + electric motor), (IC engine + hydraulic system)


- Fuel cell
