  2. United States biofuel policies - Wikipedia

    en.wikipedia.org/wiki/United_States_biofuel_policies

    The first agency addressed is the Environmental Protection Agency, directing the Administrator of the EPA to provide grants for research, development, and implementation of renewable fuel production technologies in specified states with low rates of ethanol production, including low rates of production of cellulosic biomass ethanol. [7]

  3. Corn ethanol - Wikipedia

    en.wikipedia.org/wiki/Corn_ethanol

    The Renewable Fuels Association (RFA), the ethanol industry's lobbying group, claims that ethanol production increases the price of corn by increasing demand. The RFA claims that ethanol production has positive economic effect for US farmers, but it does not elaborate on the effect for other populations where field corn is part of the staple diet.

  4. Sustainable biofuel - Wikipedia

    en.wikipedia.org/wiki/Sustainable_biofuel

    In 2008, the Roundtable for Sustainable Biofuels released its proposed standards for sustainable biofuels. This includes 12 principles: [2] "Biofuel production shall follow international treaties and national laws regarding such things as air quality, water resources, agricultural practices, labor conditions, and more.

    Oceans often act as renewable resources. Sawmill near Fügen, Zillertal, Austria Global vegetation. A renewable resource (also known as a flow resource [note 1] [1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.

  6. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    Cellulosic biomass, derived from non-food sources, such as trees and grasses, is also being developed as a feedstock for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form (E100), but it is usually used as a gasoline additive to increase octane ratings and improve vehicle emissions.

  7. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    Larger hydrocarbons [17] and ethanol [18] can also be produced from carbon dioxide and hydrogen. All synthetic hydrocarbons are generally produced at temperatures of 200–300 °C, and at pressures of 20 to 50 bar. Catalysts are usually used to improve the efficiency of the reaction and create the desired type of hydrocarbon fuel. Such ...

  8. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy (also called green energy) is energy made from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries.

  9. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    Clean production bioethanol [20] is a biofuel obtained by maximizing non-greenhouse gas emitting (renewable) resources: energy directly consumed to make the ethanol is renewable energy . The farm equipment and ethanol plant use an ethanol engine , biodiesel , air engine or electricity cogenerated during ethanol production, or even wind power ...
