Fossil fuel is any naturally occurring carbon compound found in the Earth's crust that has been produced by anaerobic conditions and high pressures acting on dead organisms. These fossil fuel deposits are typically found at depths beneath the Earth surface or ocean floor of tens of meters to kilometers, and often occur in large agglomerations of gas, liquid or solid matter. Presently, combustion of fossil fuels account for over 86 percent of the world's artificial energy delivered to the human society. These fuels are considered non-renewable in that their natural creation time requires millions of years. The extraction, processing and combustion of fossil fuels causes significant adverse environmental consequences to biodiversity, air quality and water quality, as well as substantial impacts to human health and mortality. These processes also generate large quantities of greenhouse gases delivered to the atmosphere. Fossil fuels are utilized as feedstock for synthesis of a wide variety of petrochemicals and medicinal products. These fuels may occur as gases ranging from low molecular weight compounds such as methane, to liquid petroleum products, and also include solids, chiefly coals.
