Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels (petrol or petrodiesel). The term also refers to any technology (e.g. electric cars, hybrid electric vehicles, solar-powered vehicles) powering an engine that does not solely involve petroleum. [citation needed]
A phase-out of fossil fuel vehicles are proposed bans or discouragement (for example via taxes) on the sale of new fossil-fuel powered vehicles or use of existing fossil-fuel powered vehicles, as well the encouragement of using other forms of transportation. Vehicles that are powered by fossil fuels, such as gasoline (petrol), diesel, kerosene ...
As of 2017, there were more than 21 million E85 flex-fuel vehicles in the United States, [1] up from about 11 million flex-fuel cars and light trucks in operation as of early 2013. [20][21] The number of flex-fuel vehicles on U.S roads increased from 1.4 million in 2001, to 4.1 million in 2005, and rose to 7.3 million in 2008. [3][19] E85 flex ...
Renewable Fuel Standard (United States) The Renewable Fuel Standard (RFS) is an American federal program that requires transportation fuel sold in the United States to contain a minimum volume of renewable fuels. It originated with the Energy Policy Act of 2005 and was expanded and extended by the Energy Independence and Security Act of 2007.
A Natural Gas Vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGV's rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.
A conical flask of "green" jet fuel made from algae. Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. [ 1 ][ 2 ] When made from seaweed (macroalgae) it can be ...
Synthetic production of liquid fuels (i.e., gasoline and oil substitutes) in the United States has a long history. In the 19th century, dozens facilities produced oil, gas, grease and paraffin from coal, but by 1873, cheap petroleum caused the last coal oil plant to close. The commercial scale shale oil extraction began in 1857 at shale oil ...
