The Energy Policy Act of 1992 defines alternative fuels as methanol, denatured ethanol, and other alcohol; mixtures containing 85 percent or more (but not less than 70 percent as determined by the Secretary of Energy by rule to provide for requirements relating to cold start, safety, or vehicle functions) by volume of methanol, denatured ethanol, and other alcohols with gasoline or other fuels. Includes compressed natural gas, liquid petroleum gas, hydrogen, coal-derived liquid fuels, fuels other than alcohols derived from biological materials, electricity, or any other fuel the Secretary of Energy determines by rule is substantially not petroleum and would yield substantial energy security and environmental benefits.
Japan is pursuing alternative fuels in order to reduce its dependence on oil. Oil once accounted for nearly 80% of Japan's demand for primary energy. But the oil crises of the 1970s prompted the government to set targeted reductions of this figure. Calls for development of oil alternatives have also grown around the world in recent years from the standpoint of preventing global warming. Natural gas is a common alternative fuel used in industry and electric power generation, and nuclear power and coal are also referred to as alternative fuels in the wide definition. With automobiles responsible for 40% of Japan's crude oil consumption, the nation is promoting development of such natural-gas-based fuels as gas-to-liquid fuels and dimethyl ether as well as fuel cells, which generate electricity through a chemical reaction between hydrogen and oxygen.
Substitutes for traditional liquid, oil-derived motor vehicle fuels like petrol and diesel. Includes alcohol, biodiesel, compressed natural gas, and others. The alternatives are promoted for pollution reduction properties and/or to reduce dependence on oil.
transportation fuels other than gasoline or diesel. Includes natural gas, methanol, and electricity.
Fuels that can replace ordinary gasoline, such as compressed natural gas (CNG), alcohols, liquefied petroleum gas (LPG), and electricity. Alternative fuels may have particularly desirable energy efficiency and pollution reduction features. The 1990 Clean Air Act encourages development and sale of alternative fuels.
Are those defined by the Energy Policy Act of 1992, including biodiesel, electricity, ethanol, hydrogen, natural gas, and propane. Since 1992, when the Energy Policy Act (EPAct) was passed, only one new fuel has been recognized as an alternative fuel under the EPAct petitions provision. P-Series fuels were added to the list of alternative fuels in 1999.
Any method of powering an engine that does not involve petroleum (oil). Some alternative fuels are natural gas, propane, hydrogen, hydrogen-blended natural gas, and electricity.
Low-polluting fuels which are used to propel a vehicle instead of high-sulfur diesel or gasoline. Examples include methanol, ethanol, propane or compressed natural gas, liquid natural gas, low-sulfur or "clean" diesel and electricity.
Vehicle engine fuels other than standard gasoline or diesel. Typically, alternative fuels burn cleaner than gasoline or diesel and produce reduced emissions. Common alternative fuels include methanol, ethanol, compressed natural gas (CNG), liquified natural gas (LNG), clean diesel fuels and reformulated gasoline.
Fuels such as methanol, ethanol, natural gas, and liquid petroleum gas that are cleaner burning and help to meet ARB's mobile and stationary emission standards. These fuels may be used in place of less clean fuels for powering motor vehicles.
A popular term for "non-conventional" transportation fuels derived from natural gas (propane, compressed natural gas, methanol, etc.) or biomass materials (ethanol, methanol).
Substitutes for traditional liquid, oil-derived motor vehicle fuels like gasoline and diesel. Includes methanol, ethanol, compressed natural gas, and others.()
any fuel source other than gasoline or diesel such as alcohols, electricity, natural gas, or propane. Many alternative fuels are cleaner burning than fossil fuels and may, in the future, be used in place of fossil fuels.
Other fuels that can be substituted for the fuel in use. In the case of natural gas, the most common alternative fuels are distillate fuel oils, residual fuel oils, coal and wood.
Methanol, denatured ethanol, and other alcohols, separately or in mixtures of 85 percent by volume or more (or other percentage not less than 70 as determined by Department of Energy rule) with gasoline or other fuels. Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), hydrogen, coal-derived liquid fuels, fuels other than alcohols derived from biological materials, electricity, or any other fuel determined to be substantially not petroleum.
Fuels that can replace ordinary gasoline. Alternative fuels may have particularly desirable energy efficiency and pollution reduction features. Alternative fuels include compressed natural gas, alcohols, liquefied petroleum gas (LPG), and electricity. The 1990 Clean Air Act encourages development and sale of alternative fuels.
Environmentally friendly fuels that provide better gas mileage, do not release harmful toxins, and do not support oil wars. Most if not all Diesel engines can be converted to run on vegetable oil.
