Solar power

  1. 1. Solar Power By Aria
  2. 2. What is solar power and how it works? <ul><li>Solar power is energy from the sun. The suns light shines on to the solar panels and the solar panels reflect the heat to a machine that spreads hot water all over the earth. </li></ul>
  3. 3. solar panels
  4. 4. Facts about solar power <ul><li>  </li></ul><ul><li>          It takes 8 minutes 17 seconds for light to travel from the sun’s surface to earth. </li></ul><ul><li>          A Swiss scientist, Horace de Saussure invented the world’s first solar energy collector, or ‘hot box’ in 1767. </li></ul><ul><li>          In the 1830s British astronomer John Herschel used a solar energy collector box to cook food during an expedition to Africa. </li></ul><ul><li>          Enough sunlight falls on the earth every minute to meet the world’s energy demands for an entire year. </li></ul><ul><li>·          http://www.uk-energy-saving.com/solar_energy.html </li></ul>
  5. 5. suns light shining to earth
  6. 6. More facts <ul><li>         Solar energy is a term for describing a range of methods for obtaining energy from the sun. Many people immediately think about solar panels when hearing solar energy but wind, biomass and hydro power are all forms of solar energy. Wind develops through highs and lows in temperature. Wind drives waves. Rainfall, created by sun-warmed evaporated water feeds the rivers that are sources for hydro power. </li></ul><ul><li>  </li></ul><ul><li>         http://www.alternate-energy-sources.com/facts-about-solar-energy.html </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>  </li></ul>

  8. 8. More facts <ul><li>         Even fossil fuels are forms of stored solar energy. Coal, oil and gas formed hundreds of millions of years ago from decomposed plant matter. Plant matter that grew by aid of the sun! </li></ul><ul><li>         Solar energy is successfully being used for cooking, cooling, heating, communications, driving space craft, lighting and many more purposes. </li></ul><ul><li>  </li></ul><ul><li>         http://www.alternate-energy-sources.com/facts-about-solar-energy.html    </li></ul>
  9. 9. Lots of solar panels
  10. 10. More facts <ul><li>         Building methods have for many centuries taken account of the sun’s movements in optimizing its warmth and light. </li></ul><ul><li>         In the late 15th century Leonardo Da Vinci already conceived of an industrial use of solar power by employing concave mirrors to heat water. </li></ul><ul><li>         Even fossil fuels are forms of stored solar energy. Coal, oil and gas formed hundreds of millions of years ago from decomposed plant matter. Plant matter that grew by aid of the sun! </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>         http://www.alternate-energy-sources.com/facts-about-solar-energy.html    </li></ul>

  12. 12. Do you think solar power  is sutible for Hong kong and why? <ul><li>Yes it is good for hong kong because its mainly sunny and hot and when it is sunny the sun shines very bright. </li></ul>
  13. 13. Do you think where your from is sutible for solar power? <ul><li>Where im from yes and no because in some seasons its very sunny but in other seasons its not so sunny. </li></ul>
