Fossil fuels


Fossil fuels refer to fuels that have been formed of biomass and stored underground millions of years ago. Fossil fuels include coal, lignite, natural gas and fuel oils refined from crude oil. In international classifications peat is often classified as fossil fuel, although it is a clearly younger fuel than them.
