The limited supplies, uneven distribution, and rising costs of fossil fuels, such as oil and gas, create a need to change to more sustainable energy sources in the foreseeable future. With as much dependence that the U.S. currently has for oil and with the peaking limits of oil production; economies and societies will begin to feel the decline ...

For example, see Midway-Sunset Oil Field, California's largest oilfield. Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high ...
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.
The industry is the largest industrial source of emissions of volatile organic compounds (VOCs), a group of chemicals that contribute to the formation of ground-level ozone . [44] The combustion of fossil fuels produces greenhouse gases and other air pollutants as by-products.
Energy resources may be classified as primary resources, suitable for end use without conversion to another form, or secondary resources, where the usable form of energy required substantial conversion from a primary source. Examples of primary energy resources are wind power, solar power, wood fuel, fossil fuels such as coal, oil and natural ...
Primary energy sources are transformed by the energy sector to generate energy carriers. Energy resources must be processed in order to make it suitable for final consumption. For example, there may be various impurities in raw coal mined or raw natural gas that was produced from an oil well that may make it unsuitable to be burned in a power ...
