    - - Natural gas,the cleanest fossil fuel,is a highly efficent form of energy and compared to other fuels it has Fewer impurity, it is less chemically complex.It is composed chiefly of metano,a colorless,odorless,flammable gas which represents an ideal fuel and an important energy source
    - - Wood
        
        Wood was once man's main fuel,buttandosi coal,petrolium have largely replaced.
      - Coals
        
        Antracite coal,which has valuta a fuel,because it burns slowly,producing a lot of heat and very little smoke
        
        Lignite, which contains a great deal of moisture and produces less heat than anthracite and bitumous coal
        
        Bituminouse coal,the mostro important coal user for generating eletricity,
  - - - Nuclear fusione,energy is released when atorms are combined or fused together the form a larger atom.This is how the sun produces energy.
      - Nuclear fision, atoms are split apart to form smaller atoms,releasing energy
