Production of Energy

• A fuel is a substance that can be used as a source of energy
• Burning fuels ( like oil ) to form oxides is an exothermic reaction.
• The heat from burning fuels is used in power plants to create steam from water and turn turbines
• A combustion process requires the presence of a fuel, oxygen and heat.
• A good fuel must:

  • Be cheap
  • Be available in large quantities
  • Ba a liquid at room temperature
  • Have high efficiency (produce a large amount of energy)
  • Not produce polluting gases
