  2. McKelvey diagram - Wikipedia

    en.wikipedia.org/wiki/McKelvey_diagram

    A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery. The diagram is used to estimate the uncertainty and risk associated with availability of a natural resource.

    Fossil fuel divestment or fossil fuel divestment and investment in climate solutions is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels.

  5. Primary energy - Wikipedia

    en.wikipedia.org/wiki/Primary_energy

    Sankey diagram for the United States 2016 shows that 66.4% of primary energy ends up as waste heat. Where primary energy is used to describe fossil fuels, the embodied energy of the fuel is available as thermal energy and around two thirds is typically lost in conversion to electrical or mechanical energy. There are very much less significant ...

  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 ...

  7. Carbon-based fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_fuel

    Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...

    en.wikipedia.org/wiki/World_energy_supply_and...

    Fuel comes in three types: Fossil fuel is natural gas, fuel derived from petroleum (LPG, gasoline, kerosene, gas/diesel, fuel oil), or from coal (anthracite, bituminous coal, coke, blast furnace gas). Secondly, there is renewable fuel (biofuel and fuel derived from waste). And lastly, the fuel used for district heating.
