Fuel traditionally is a substance that may be burned to produce energy (heat, light, or power). In more recent times fuelds can also be nuclear, and these do not require burning to produce energy. The chief property of fuel is its caloric value - the amount of heat produced by complete combustion of a unit mass of its volume.
Some fuels that have been found and used throughout history include wood, animal and vegetable oil, peat, coal, and dried dung.
Common fuels today are petroleum and natural gas.
Many fuels also have a number of incombustibles, such as ash, that could cause air pollution and have unhealthy or even toxic qualities from fuel production.
