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.
For Monroney fuel economy the equation is. where. is expressed as miles per gallon gasoline equivalent (as shown in the Monroney label) E G = {\displaystyle E_ {G}=} energy content per gallon of gasoline = 115,000 Btu /gallon, as set by U.S. DoE and reported by the Alternative Fuel Data Center.
Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline. It is difficult to compare the cost of gasoline ...
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
“In 2024 the aviation industry worldwide used almost 100 billion gallons of fuel,” said Mohnen. “But by the year 2050, (European leaders) told the aviation industry they need to have 70% of ...
The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [5] The LCOE is an estimation of the cost of production of energy, thus it tells nothing about the price for consumers and is most meaningful from the investor’s point of view.
E85. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. [1]
Similarly, whereas selling any fuel containing more than 10% ethanol is currently illegal in some states, this is rapidly changing. For example, Florida proposed changing state law to permit the sale of alternative fuels such as E85 at an October 7, 2005 meeting, and held public hearings on October 24. Before higher level blends of ethanol were ...
