  8. 8. The Problem with Solar Power?<br />Efficiency<br />
  9. 9. The Problem with Solar Power?<br />You need the sun.<br />
  10. 10. Wind Power<br />
  11. 11. Modern Wind Power<br />
  12. 12. What is Good?<br />University of Delaware:<br />The total energy power which is “economically viable” is more than 7 times the world’s demand for electricity<br />Uses very little land<br />Land around it is still usable<br />
  13. 13. What is Bad?<br />The wind does not always blow<br />
  14. 14. Hydropower<br />
  15. 15. How does hydro power work?<br />Water is built up behind the dam and then allowed to flow through it.<br />Illustrations taken from RenewableEnergyResource.net<br />
  16. 16. How does hydro power work?<br />Water is built up behind the dam and then allowed to flow through it.<br />The flow of water is then channeled through a turbine, which spins the generator<br />Illustrations taken from RenewableEnergyResource.net<br />
  17. 17. How much power can one dam produce?<br />The Three Gorges dam produces as much energy each year as:<br />“Great Wall across the Yangtze” <br />-PBS<br />25 million tons of crude oil<br />50 million tons of coal<br />15 nuclear power plants<br />
  18. 18. What’s the catch?<br />Restricted water flow downstream<br />
  19. 19. What’s the catch?<br />Restricted water flow downstream<br />Dam failures<br />
  20. 20. Some Forms of Renewable Energy<br />Solar<br />Wind<br />Hydro<br />
