1. Energy Resources 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.

5. 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

6. How oil forms  Ocean Odyssey - Oil [www.keepvid.com].mp4 Ocean Odyssey - Oil [www.keepvid.com].mp4 Ocean Odyssey - Oil [www.keepvid.com].mp4

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

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

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

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

17. Nuclear Energy  Advantages: Don’t produce CO 2 (clean energy) Don’t produce CO 2 (clean energy) Little Uranium makes lots of energy Little Uranium makes lots of energy  Disadvantages: Risk of nuclear accident Risk of nuclear accident High costs to built and operate High costs to built and operate

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

20. Biomass  Advantages: Usually easy to find Usually easy to find Can use trees, grass, animal wastes Can use trees, grass, animal wastes  Disadvantages: Produces CO 2 and particulates (smoke, ash) Produces CO 2 and particulates (smoke, ash)

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

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

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