1 Conventional Energy Fossil Fuels

2 What is a Fossil Fuel? Fossil Fuels - energy sources that are formed over geologic time as a result of the compression and partial decomposition of organic matter Are fossil fuels renewable or nonrenewable? Fossil fuels are nonrenewable Formation occurs over thousands or millions of years

3 Coal What is coal? Coal - Concentrated carbon from compressed organic material Four different types of coal that are classified according to how it was formed

4 Fossil Fuels - Petroleum What is petroleum? Petroleum - natural crude oil found underground and on Earth’s surface Crude Oil - a mixture of compounds of hydrogen and carbon What is crude oil used for? Can be burned to release energy Refined into gasoline or kerosene

5 Fossil Fuels - Natural Gas How is natural gas formed? Natural Gas -Gases produced from bacteria that is trapped in areas that don’t require a lot of oxygen The bacteria release methane, a component of natural gas

6 1.Choose a row, column, or diagonal of three concepts. Write a statement showing the connections between the terms AND giving deep meaning to each term. 2. Choose another set of three terms and repeat. 3. Must have 2 statements. Can have a third statement for extra credit.

7 Alternative Energy

8 What is renewable energy? Renewable Energy - energy that can be replaced What are some examples of renewable energy?

9 Solar Energy What is solar energy? Solar Energy - Using the sun’s energy to provide energy What are some every day things that use solar energy? Calculators Homes Solar Cookers

10 Hydroelectric What does the prefix “hydro-” mean? Water What does the suffix “-electric” mean? Power Hydroelectric Power - power provided by water Renewable Nonpolluting

11 Hydroelectric Niagara Falls Waterfall produces electricity for both the U.S. and Canada Water from the falls is diverted into massive turbines The turbines turn, producing mechanical energy The mechanical energy produces electrical energy

12 Hydroelectric Where else can we harvest hydroelectric power? Oceans Rivers What is one problem with hydroelectric power? Barriers (power plants) in the water can change the water level These can also disrupt coastal and marine ecosystems

13 Geothermal Energy What is geothermal energy? Geothermal Energy - Energy produced by naturally occurring steam and hot water Includes hot springs such as Yellowstone National Park What can this energy be used for? Heat, electricity, recreation The U.S. Dept of Energy estimates that if the geothermal reservoirs in the US were developed, they could provide up to 30 times as much energy as the country uses

14 Geothermal Energy What are some advantages? There’s lots of it It’s reliable and continuous Pollutant-free Are there disadvantages? Need to monitor carefully to make sure reservoirs don’t get tapped out too fast (water must be able to be replaced and warmed up to be used again) Water usually contains a large amount of minerals Transportation of geothermal energy is not practical

15 Wind Energy What is wind energy? Wind Energy - The capture of wind power for human use Have been using for over 2000 years Recently, we use wind farms, which replace the windmills that used to pump water from underground wells Wind turbines convert wind to mechanical energy, which then produces electrical energy

16 Wind Energy Advantages? Unlimited energy resource (especially at higher altitudes) Wind farms can be built quickly and expanded as needed Nonpolluting Disadvantages? Must have steady winds (if not, need a back-up system) Not attractive Interfere with birds Noisy

17 Pass Out of Class What alternative energy source would be least damaging to the environment if the required technology could be developed to harness and use it? EXPLAIN!

21 Presentation Expecatations Dress - Look nice! If you don’t own something nice, borrow something! Practice! Speak with authority! Know what you are talking about! If you don’t know, it’s okay to say “I don’t know.” Make sure you leave time for questions As the audience, don’t be afraid to ASK questions. You’ll need to know more for your scrapbook!
