Solar energy

  1. 1. Solar Energy<br />May 12, 2010<br />
  2. 2. Objectives<br />Determine how the sun produces energy<br />Describe what is used to collect the sun’s energy<br />Identify areas where solar energy would be profitable<br />
  3. 3. How does the sun produce energy?<br />Fusion<br />The sun fuses together 2 hydrogen molecules<br />It can only happen because the core of the sun is so hot, 19 million degrees Fahrenheit<br />Energy radiates from the sun in the form of light<br />Light contains the energy of the sun<br />
  4. 4. Getting the energy from the light<br />The earth only gets a very small portion of the total energy the sun produces<br />That energy is indirectly responsible for most forms of energy on earth<br />Fossil Fuels<br />Wind Energy<br />Biomass<br />
  5. 5. Getting Energy from Light<br />Light from the sun can provide energy<br />Collect light using solar panels aka photovoltaic (PV) cells<br />These panels are pointed at the sun to receive sunlight<br />We use the energy for transportation, heating, cooling, and electricity<br />

  7. 7. Where would solar energy be best?<br />
  8. 8. Where would solar energy be best?<br />
  9. 9. Pros and Cons of solar energy<br />Pros<br />There is a huge amount of energy present from the sun<br />Fuel does not cost anything to produce<br />Does not pollute the atmosphere<br />Cons<br />Energy only available during the day<br />High cost to build<br />Need a large area to build<br />
