Solar energy

  1. 1. SOLARenergy
  2. 2. what is it?• Solar power produces electricity by using solar panels; sunlight is collected then converted• Can be installed in individual housing or in larger communities (ie. schools, malls, etc)• Used mostly in remote locations
  3. 3. solarenergy’spotential• 600 square meters of solar paneling can easily cost approximately 100,000 dollars.• In one minute more sunlight falls on the earth than what is utilized by the whole population in one year• Sahara desert can produce 450 tarawats. Global annual consumption = 13 TW
  4. 4. solar energytrends
  5. 5. solar energytrends
  6. 6. solar energytrends
  7. 7. pros• Renewable, Clean source of energy, sustainable (environmental)• Safer (socio-environmental)• Reliable requiring minimal maintenance and quiet (social)• No transportation of energy – no dependency on large energy networks (socioeconomic)• More self-sufficient --> local power grid (economic)• Self-sufficient, saves money in the long run (economic)
  8. 8. cons• Sunlight is free, installation is not (economic)• Large scale conversion of sunlight into electricity --> expensive for general use (socioeconomic) • Ie. school• Unrealistic for LEDCs – too high of an initial cost (political)• Cannot be stored, unlike oil, therefore cannot be transferred
