Our main energy sources

  • Industrialised countries need large amounts of energy
  • Most of this energy comes form fossil fuels which are burnt in power stations, factories, homes and vehicles
  • These fossil fuels formed millions of years ago, and are non-renewable
  • Once the fossil fuels have been used up there will be no more to replace them

Oil is useful forother things too

  • Oil is a mixture of different compounds
  • We can separate these substances by a process called fractional distillation
  • These fractions include fuels like petrol, diesel and aviation fuel
  • Parts of oil are also used to make plastics, medicines, paints, dyes and even wax candles
