  • Lignite (brown coal)
  • Bituminous coal
  • Anthracite (hard coal)

2. Crude Oil (Petroleum)

Oil is a liquid fossil fuel that is refined into various products like gasoline, diesel, jet fuel, and lubricants. It is found deep underground and extracted through drilling.

Common petroleum products include:

  • Petrol (Gasoline)
  • Diesel
  • Kerosene
  • LPG (Liquefied Petroleum Gas)

3. Natural Gas

Natural gas is a gaseous fossil fuel made primarily of methane. It is used for cooking, heating, and electricity generation and is considered cleaner than coal and oil.

Forms of natural gas:

  • Compressed Natural Gas (CNG)
  • Liquefied Natural Gas (LNG)

Common Uses of Fossil Fuels

Deeply integrated into daily life and the global economy.

1. Electricity Generation
