  2. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    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.

  3. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    Sediments, including fossil fuels, freshwater systems, and non-living organic material. Earth's interior (mantle and crust). These carbon stores interact with the other components through geological processes. The carbon exchanges between reservoirs occur as the result of various chemical, physical, geological, and biological processes.

  4. Geochemistry of carbon - Wikipedia

    en.wikipedia.org/wiki/Geochemistry_of_carbon

    Yet it is the twelfth most common element there. In the rock of the lithosphere, carbon commonly occurs as carbonate minerals containing calcium or magnesium. It is also found as fossil fuels in coal and petroleum and gas. Native forms of carbon are much rarer, requiring pressure to form. Pure carbon exists as graphite or diamond. [1]

  6. Coal - Wikipedia

    en.wikipedia.org/wiki/Coal

    Deaths caused as a result of fossil fuel use, especially coal (areas of rectangles in chart) greatly exceed those resulting from production of renewable energy (rectangles barely visible in chart). [122] The use of coal as fuel causes health problems and deaths. [123] The mining and processing of coal causes air and water pollution. [124]

  7. Oil shale - Wikipedia

    en.wikipedia.org/wiki/Oil_shale

    Oil shale can be burned directly in furnaces as a low-grade fuel for power generation and district heating or used as a raw material in chemical and construction-materials processing. [1] Heating oil shale to a sufficiently high temperature causes the chemical process of pyrolysis to yield a vapor.

  8. Lignite - Wikipedia

    en.wikipedia.org/wiki/Lignite

    Lignite (derived from Latin lignum meaning 'wood'), often referred to as brown coal, [1] is a soft, brown, combustible sedimentary rock formed from naturally compressed peat.It has a carbon content around 25–35% [1] [2] and is considered the lowest rank of coal due to its relatively low heat content.

  9. Chemical energy - Wikipedia

    en.wikipedia.org/wiki/Chemical_energy

    Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...
