  2. Ethanol fuel - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel

    For each billion ethanol-equivalent gallons of fuel produced and combusted in the US, the combined climate-change and health costs are $469 million for gasoline, $472–952 million for corn ethanol depending on biorefinery heat source (natural gas, corn stover, or coal) and technology, but only $123–208 million for cellulosic ethanol ...

  3. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    At lower quantities of production, Wang finds it appropriate to credit corn ethanol based on the input energy requirement of the feed product or good that the ethanol by-product displaces. [8] In 2004, a USDA report found that co-products accounting made the difference between energy ratios of 1.06 and 1.67.

    Now, to calculate gas cost per mile simply divide the total miles driven by the total cost of your last fill-up. Using the prior example, if the gas cost $2.49 per gallon, your 15-gallon fill-up ...

  6. Corn ethanol - Wikipedia

    en.wikipedia.org/wiki/Corn_ethanol

    Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States, mandated to be blended with gasoline in the Renewable Fuel Standard. Corn ethanol is produced by ethanol fermentation and distillation. It is debatable whether the production and use of corn ethanol results in lower greenhouse gas ...

  7. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1] Energy density is the amount of chemical energy per unit volume of the fuel, expressed in SI units as joule per litre (J/L) or equivalent units. [2]

    The Alternative Motor Fuels Act (AMFA) enacted in 1988 [15] provides Corporate Average Fuel Economy (CAFE) incentives for manufacturing alternative fuel vehicles (AFVs) that are powered by ethanol, methanol, or natural gas fuels, either exclusively or in conjunction with gasoline or diesel fuel.

  9. E85 - Wikipedia

    en.wikipedia.org/wiki/E85

    In 2010, the cost of fuel in the US averaged US$3.42, while the cost for E85 averaged US$3.09, or 90% of the cost of gasoline. [ 21 ] [ 22 ] In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in ethanol-based vehicles when compared to traditional, gas-powered Tauruses.
