1 Natural Resources

2 Warm Up  What is energy?  Make a list of all the things today that you used that require energy.  Group these items together by what type of energy those items require.

3 Energy Use in the U.S.  Where/How is it used?  Where does the energy come from?

4 Renewable vs. Nonrenewable  Put your type of energy under the correct category on the board  Renewable  Definition  Examples  Nonrenewable  Definition  Examples

5 Fossil Fuels  Definition  Why are the good energy sources?  Made of hydrocarbons  Burn hot  Creates lots of energy  Release pollution  Types  Petroleum  Coal  Natural Gas

6 Coal  Fossil fuel  Former bog/swamp  Decaying plant/ animal material  Acidic  Low oxygen  Pressure and time  Contains sulfur

7 Coal – Where and How?  Mining  Deep  Strip  Refinement  Transportation  Mostly U.S.  Used for  Electricity

8 Coal Advantages (Pros) Disadvantages (Cons)  EES – 1 EES – 1  EES – 3 EES – 3  EES – 2 EES – 2  EES – 6 EES – 6

9 Daily Review #3 11. Describe how petroleum, natural gas and coal are similar. 12. Describe how petroleum, natural gas and coal are different. 13. In your opinion, what is the most important advantage of coal and why? 14. In your opinion, what is the most important disadvantage of coal and why?

10 Nuclear Fusion  Combining 2 atoms  Some mass changed into energy  Much more energy than fission  Requirements  High speed collisions  High temperatures  Occurs naturally  Sun/stars  Limits to use  High temperatures  No container  Requires lots of energy  Enormous potential

11 Nuclear Fission  1 atom to 2  Chain reaction  Where?  Reactors  Power plants  Subs  Aircraft carriers  Generates electricity  Creates nuclear waste  European model

12 Nuclear Power Plant  Reactor  Containment dome  Fuel rods  Control rods  Produces heat  Moderator  Heats other water  Creates steam  Turns a turbine  Powers a generator  Creates electricity  Water cooled and reused  Spent fuel  Radioactive  Storage issues

13 Nuclear Fission Advantages (Pros) Disadvantages (Cons)  EES – 1 EES – 1  EES – 3 EES – 3  EES – 2 EES – 2  EES – 6 EES – 6

14 Daily Review #4 15. Describe how electricity is made in a nuclear power plant. 16. How are fission and fusion similar? Different? 17. In your opinion, what is the most important advantage of nuclear fission and why? 18. In your opinion, what is the most important disadvantage of nuclear fission and why?

15 Solar  Where?  Passive  Greenhouses  South-facing windows  Absorbing materials

16 Photovoltaics Video Movement of electrons Where? – Buildings – Farms Farms – Space Cost

17 Photovoltaics Advantages (Pros) Disadvantages (Cons)  EES – 1 EES – 1  EES – 3 EES – 3  EES – 2 EES – 2  EES – 6 EES – 6
