            Energy Sources
Sources of energy can come from non-renewable or
               renewable resources.

   Non-Renewable             Renewable
     Fossil Fuels              Wind
   Oil (Petroleum)         Geothermal
   Coal                     Biomass
   Natural Gas                Solar
         Nuclear           Hydro-Electric
                               Wave
                               Tidal
   Non-Renewable Energy:

                 Oil
Advantages:
      World set up for oil
      Relatively Cheap

Disadvantages:
      40 years supply readily available
      CO2 causing global warming
      Smog
      Economic skills to develop global
       carbon credit system
      Oil wars

Your Challenge:
    Political skills to reduce
     consumption (especially in rich
     countries)
    Economic skills to develop global
     carbon credit system
    Non-Renewable Energy:

               Coal

Advantages:
     Cheap
     Plentiful - at least 1000 years supply

Disadvantages:
     Smog
     CO2 causing global warming
     Releases radio active waste

Your Challenge:
     Political skills and options to create
      alternatives.
     Develop clean burning coal stations
  Non-Renewable Energy:

             Gas
Advantages:
    Cheap
    Natural
    Popular

Disadvantages:
     Existing gas fields running out
     Highly flammable
     Create cavities in the Earth


Your Challenge:
    Research how best to utilise the
      gas e.g. home heating
  Non-Renewable Energy:

Nuclear Power
Advantages:
     High energy production
     No greenhouse gases
     Cheapest energy source in
      Europe
     Fusion power could last forever


Disadvantages:
     Uranium will last only 70 years
      with current consumption
     Disposing of radioactive waste


Your Challenge:
       Currently have nuclear fission,
        need to develop nuclear fusion.
      Summary

   Advantages:
      Each household can
       produce some of their power
      Usually for hot water heating
      Excellent for remote
       locations

   Disadvantages:
      Unpredictable sunshine
       hours
      Bulky batteries with limited
       storage capacity
      Expensive capital cost


     Your Challenge:
      Explore technologies for low
       cost solar power e.g. paint
      Renewable Energy:
