A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2]Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] Other commonly used derivatives include kerosene and propane. Fossil fuels range from volatile materials with low carbon to hydrogenratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.
