  1. EnergyResources Earth Sci Ch. 26 The Amazing Mr. Batts

  2. Traditional sources of Energy • Wood-fuel for heating and cooking • Field crops and fecal material are also burned.

  3. Fossil Fuels • Energy sources that formed over geologic time (millions of years) • From decomposition and compression of organic matter • Ex= coal, oil, natural gas, petroleum

  4. How oil forms • Ocean Odyssey - Oil [www.keepvid.com].mp4

  5. Alternative Energy Resources

  6. Hydroelectic Power - How it Works [www.keepvid.com].mp4 • Geothermal Energy Process [www.keepvid.com].mp4

  7. Solar • Advantages: • Will last forever • Free • No pollution • Disadvantages: • Can’t use at night, unless use batteries • Solar panels and installation are expensive

  8. Hydroelectric power • Advantages: • Neverending supply • Nonpolluting • Disadvantages: • Must be located near a river • Can flood large areas • Alters ecosystems

  9. Geothermal Energy • Advantages: • Abundant and reliable • Disadvantages: • When tapped, cooler water takes its place • Has minerals that can clog pipes

  10. Wind Energy • Advantages: • Unlimited energy source • Wind farms can be built quickly • Nonpolluting, don’t need water • Disadvantages: • Not steady winds in all areas • Not attractive

  11. Nuclear Energy • Advantages: • Don’t produce CO2 (clean energy) • Little Uranium makes lots of energy • Disadvantages: • Risk of nuclear accident • High costs to built and operate

  12. Japan videos • YouTube - Caught on Tape: Tsunami hits Japan port town • YouTube - Scary footage: Tsunami waves raging, buildings burn after 8.9 Japan earthquake

  13. Biomass • Advantages: • Usually easy to find • Can use trees, grass, animal wastes • Disadvantages: • Produces CO2 and particulates (smoke, ash)

  14. How can we use energy more efficiently? • (student response) • Cars, at home, at school, electricity, appliances, carpooling, insulation,

  15. Human impacts • Ozone hole- CFCs • Global warming • Acid rain (pH less than 5.0; sulfur dioxides and nitrogen oxides

  16. Water Usage in the US • 41% Agriculture • 38% Power plant cooling • 11% Industry • 10% Public
