energy resources and their uses

• the main energy resources are:

  • fossil fuels - coal, oil, gas
  • nuclear fuel
  • bio-fuel
  • wind
  • hydro-electricity
  • geothermal
  • the Sun
  • water waves
  • tidal
• • non-renewable energy resources are finite
  • they damage the environment.
  • they are reliable
• • renewable energy resources will never run out
  • they damage the environment but less than non-renewable
  • do not provide that much energy and are unreliable
• non-renewable energy resources:

  • coal
  • oil
  • natural gas
• renewable energy resources:

  • solar
  • wind
  • water waves
  • hydro-electricity
  • bio-fuel
  • tides
  • geothermal
• non-renewable energy resources can be used for transport:

  • petrol and diesel vehicles used fuel from oil
  • coal is used in steam trains to boil water to make steam
• renewable energy resources in transport:

  • vehicles that run on pure bio-fuel or mix of petrol and bio-fuel
• non-renewable energy resources for heating:

  • natural gas used to heat water that is pumped through radiators
  • coal burnt in fireplaces
  • electric heaters use electricity generated from non-renewable sources
• renewable energy resources in heating:

  • geothermal heat pump to heat buildings
  • solar water heaters
  • burning bio-fuel
