Kapitel 1: Upcoming needs of fossil fuels.
Fossil fuels are fuels that come from old life forms that decomposed over a long period of time. The three most important fossil fuels are coal, petroleum, and natural gas.
Coal burning to provide heat
Oil and gas are hydrocarbons (molecules that have only hydrogen and carbon in them). Coal is mostly carbon. These fuels are called fossil fuels because they are dug up from underground. Coal mining digs up solid fuel; gas and oil wells bring up liquid fuel. Fossil fuel was not much used until the Middle Ages. Coal became the main kind of fuel with the Industrial Revolution.
Uses Edit
Most of the fuels people burn are fossil fuels. A big use is to make electricity. In power plants fossil fuels, usually coal, are burned to heat water into steam, which pushes a fan-like object called a turbine. When the turbine spins around, magnets inside the turbine make electricity.
Crude oil can be separated to make various fuels such as LPG, gasoline, kerosene, jet fuel, and diesel fuel. These substances are made by fractional distillation in an oil refinery. They are the main fuels in transportation. That means that they are burned in order to move cars, trucks, ships, airplanes, trains and even spacecraft. Without them, there wouldn't be much transport.
People also burn fossil fuels to heat their homes. They use coal less for this than they did long ago, because it makes things dirty. In many homes, people burn natural gas in a stove for cooking.
