Title: Coal is in short supply and nuclear energy is both expensive and potentially harmful to the environment. The solution could be in the use of renewable energy.


1
Solar Energy
  • Coal is in short supply and nuclear energy is
    both expensive and potentially harmful to the
    environment. The solution could be in the use of
    renewable energy.

2
Advantages
  • Running costs are low.
  • No carbon dioxide emissions to add to the
    Greenhouse Effect
  • No sulphur dioxide emissions to cause acid rain.

More Advantages
  • Solar panels can be quickly set up in remote
    areas
  • Local communities can benefit from small scale
    use of solar power.
  • Can be used to charge batteries to provide
    electricity when needed.

Disadvantages
  • The initial cost of solar cells can be very
    high.
  • The output is dependent on weather conditions and
    the time of day.
  • Many solar panels are needed to produce that of a
    power station

More disadvantages
  • Large areas of land are required for large scale
    generation of electricity
  • A warm reliable biome would be needed.
  • Solar cells have relatively low efficiencies

The solar panels convert the solar energy into
electrical energy. The use of solar cells are
also supplemented by the use of wind turbines
