Solar energy 2

  1. 1. Natalia Pérez and Hugo Velasco 3ºB
  2. 2. Renewable energy is energy that comes from resources which are continually replenished.
  3. 3. Types of renewable energy● Solar energy● Hydroelectricity● Geothermal● Wave power ● Wind power ● Biomass ● Biofuel ● Tidal power
  4. 4. Solar energy Energy from sunlight is captured insolar panels and converted into electricity.
  5. 5. Electric utilities use photovoltaics, a process by which solar energy is converted directly to electricity.
  6. 6. Electricity can be produced directly from solar energy using photovoltaic devices orindirectly from steam generators using solar thermal collectors to heat a working fluid.
  7. 7. Solar energy is used for heating water for domestic use, space heating of buildings,drying agricultural products, and generating electrical energy.
  8. 8. AdvantagesØ Potentially infinite energy supply.Ø Single dwellings can have own electricity supply.
  9. 9. DisadvantagesØ Manufacture and implementation of solar panels can be costly.
  10. 10. Ø The intermittent and variable manner in which it arrives at the earths surface.
  11. 11. Climate changeClimate change is a significant and lasting change in averageweather conditions, or in the distribution of weather around the average conditions.
  12. 12. Climate change is caused by factors that include oceanic processesvariations in solar radiation received by Earth, plate tectonics and volcanic eruptions,and human-induced alterations of the natural world.
  13. 13. Acid rainAcid rain is a rain or any other form of precipitation that is unusuallyacidic. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, whichreact with the water molecules in the atmosphere to produce acids.
  14. 14. SENTENCES T/FSun is the main source of energy on earth. TrueSolar energy causes pollution. FalseSolar energy will not run out for billions of years. TrueSolar energy is only available when the sun is shining. TrueThe suns rays cant be used in the form of solar energy. FalseThe energy Earth receives from the sun is very spread out. TrueSolar energy cant be converted into electrical energy. False
