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.

[2] [a] They generate about a third of the world's electricity, [3] but cause many illnesses and the most early deaths per unit of energy produced, [4] mainly from air pollution. [5] [6] World installed capacity doubled from 2000 to 2023 and increased 2% in 2023. [7] A coal-fired power station is a type of fossil fuel power station.
Fossil fuels made up the majority of generation, with natural gas providing 38% and coal 23%. Petroleum provided less than 1%. Natural gas as a proportion of fossil fuels has been increasing since the 90's, with coal peaking around 2008 and natural gas becoming the top fossil fuel in 2016. [14] Nuclear provided 20%, a level consistent since ...
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 ...
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy , which then operates an electrical generator .
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.
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.
