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.
Energy Use in the U.S. Where/How is it used? Where does the energy come from?
Renewable vs. Nonrenewable Put your type of energy under the correct category on the board Renewable Definition Examples Nonrenewable Definition Examples
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
Coal Fossil fuel Former bog/swamp Decaying plant/ animal material Acidic Low oxygen Pressure and time Contains sulfur
Coal – Where and How? Mining Deep Strip Refinement Transportation Mostly U.S. Used for Electricity
Coal Advantages (Pros) Disadvantages (Cons) EES – 1 EES – 1 EES – 3 EES – 3 EES – 2 EES – 2 EES – 6 EES – 6

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
Nuclear Fission 1 atom to 2 Chain reaction Where? Reactors Power plants Subs Aircraft carriers Generates electricity Creates nuclear waste European model
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
Nuclear Fission Advantages (Pros) Disadvantages (Cons) EES – 1 EES – 1 EES – 3 EES – 3 EES – 2 EES – 2 EES – 6 EES – 6
