  3. Alternative fuel - Wikipedia

    en.wikipedia.org/wiki/Alternative_fuel

    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 ...

  6. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...

    The standard Hubbert curve.For applications, the x and y scales are replaced by time and production scales. U.S. Oil Production and Imports 1910 to 2012. In 1956, Hubbert proposed that fossil fuel production in a given region over time would follow a roughly bell-shaped curve without giving a precise formula; he later used the Hubbert curve, the derivative of the logistic curve, [6] [7] for ...

  8. Bioplastic - Wikipedia

    en.wikipedia.org/wiki/Bioplastic

    Materials such as starch, cellulose, wood, sugar and biomass are used as a substitute for fossil fuel resources to produce bioplastics; this makes the production of bioplastics a more sustainable activity compared to conventional plastic production.

  9. Renewable fuels - Wikipedia

    en.wikipedia.org/wiki/Renewable_fuels

    Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
