The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels typically requires a geological process of millions of years. [4] Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources.
These latter sources are properly known as mineral fuels. Fossil fuels contain high percentages of carbon and include coal, petroleum, and natural gas. [12] They range from volatile materials with low carbon:hydrogen ratios like methane, to liquid petroleum to nonvolatile materials composed of almost pure carbon, like anthracite coal.
Consisting mainly of methane, natural gas is rarely used as a chemical feedstock. The extraction and consumption of natural gas is a major industry. When burned for heat or electricity, natural gas emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil and biomass fuels. [10]
Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are either carbon dioxide released by the burning of fossil fuels, or methane released from the handling of natural gas or from agriculture.
