  2. 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 electricity. [3]

  3. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels typically requires a geological process of millions of years. [4] Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources.

  4. Non-renewable resource - Wikipedia

    en.wikipedia.org/wiki/Non-renewable_resource

    Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1] An example is carbon-based fossil fuels.

  5. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy is more evenly distributed around the world than fossil fuels, which are concentrated in a limited number of countries. [28] It also brings health benefits by reducing air pollution caused by the burning of fossil fuels. The potential worldwide savings in health care costs have been estimated at trillions of dollars annually.

  6. 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.

  7. Fuel - Wikipedia

    en.wikipedia.org/wiki/Fuel

    Fossil fuels are non-renewable resources because they take millions of years to form, and reserves are being depleted much faster than new ones are being made. So we must conserve these fuels and use them judiciously. The production and use of fossil fuels raise environmental concerns.

  8. Non-Fossil Fuel Obligation - Wikipedia

    en.wikipedia.org/wiki/Non-Fossil_Fuel_Obligation

    Funding for the NFFO was originally generated by the Fossil Fuel Levy, a levy placed on all electricity consumption in the UK. This was collected by Ofgem, which paid it to the Non-Fossil Purchasing Agency, [3] a body created in 1990 by the public electricity suppliers to purchase on the supplier's behalf. The purchasing agency is based in ...

  9. Alternative fuel vehicle - Wikipedia

    en.wikipedia.org/wiki/Alternative_fuel_vehicle

    An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum-based fossil fuels such as gasoline, petrodiesel or liquefied petroleum gas . The term typically refers to internal combustion engine vehicles or fuel cell vehicles that utilize synthetic renewable fuels such as biofuels ( ethanol fuel ...
