					          Solar power

• We have used solar
  power for thousands
  of years.
• We use the sun for
  drying clothes or
  making salt or other
  things.
• Solar power comes
  from the Sun.
          Sun’s energy
• Just a tiny fraction of
  the sun’s energy that
  hits the Earth is
  enough to meet all our
  power needs many
  times over.
• We use solar panels to
  turn sunlight into
  electricity.
       disadvantages
• Sunlight is all over the
  place so you’ll need
  lots and lots of panels
  to make a useful
  amount of energy.
• Only areas of the world
  with lots of sunlight are
  suitable for solar power
  generation.
        disadvantages
• It cost lots and lots and
  lots of money when you
  are putting them up
         advantages
• There is a really
  really good thing
  about solar power -
  it doesn't harm the
  atmosphere
           advantages
• when they’re up they
  cost nothing, you barely
  need to look at them
  and they will last
• Solar power is
  renewable - it can’t run
  out unless the sun
  blows up
Is it the answer?
It’s pretty unlikely that
   solar power is going
   to be the answer but
   you can have a little
   bit of lots of things.
   Solar power is often
   an excellent extra to
   use with other
   renewable sources
          Solar power

• If you want to use
  Solar power in
  Shetland it will not be
  a good idea because
  we don’t have enough
  sun.
