  1. Warm Up 1. What are two differences between traditional and alternative energy sources? 2. List 3 traditional energy source -include 1 benefit & 1 cost 3. List 3 alternative energy source -include 1 benefit & 1 cost **Have you completed and turned in your energy madness homework??** **Turn in ALL warm ups from last week!!** Set up NEW Cornell notes: 1st & 3rd Period: page 39  2nd Period: page 41

  2. Alternate Energy in North Carolina Objective: SWBAT evaluate sources of alternate energy in North Carolina LEQ: What actions is North Carolina taking to improve energy sustainability?

  3. Table Of Contents (1st & 3rd)

  4. GEMS of Wisdom (1st & 3rd)

  5. Table Of Contents (2nd)

  6. GEMS of Wisdom (2nd)

  7. Activating Strategy What types of renewable energy sources do you think are available in North Carolina? Can you think of any renewable energy sources that are near Charlotte? What is the biggest advantage of renewable energy over nonrenewable energy? What is the difference between traditional and alternative types of energy?

  8. Political Connection! NC is one of just a few states in the US that has a legislative renewable energy mandate.  The NC Renewable Energy Portfolio Standard (REPS) requires that NC utilities must have a percentage of their retail sales come from renewable energy sources by specific dates – up to 12.5% by 2021.  BLAH, BLAH, BLAH! By 2021, 12.5% of North Carolina’s energy must come from renewable energy sources!

  9. BIG QUESTION! What types of alternative energy would be most useful and most easily accessible in North Carolina.? Aspects to consider: Weather, climate, Natural Resources

  10. CORNELL NOTES Write what is in RED and YELLOW!!

  11. Alternative Energy in NC Solar Energy Wind Energy Nuclear Energy Hydroelectric Energy

  12. What is Solar Energy? Uses photovoltaic (PV) panels to convert sunlight directly into electricity.

  13. North Carolina Solar House • The North Carolina Solar House is a house on the campus of N.C. State University in Raleigh, NC. This house is run almost entirely off of solar energy. • Virtual Tour of the NC Solar House

  14. Solar Energy: Pros & Cons*Make a t-chart!* • Pros • Once manufactured, produce no pollution • Once paid for, provide free energy • Solar energy production is very quiet, unlike energy created from fossil fuels and other forms of energy • Cons • Initial cost of solar panels is expensive • Weather can affect effectiveness of solar panels • Solar panels only work during daylight hours. This means they can only create energy during daylight hours, and must use stored energy during dark hours

  15. Nuclear Energy What is nuclear Energy?  In nuclear fission, the nuclei of heavy atoms such as uranium-235 are bombarded with neutrons. The uranium nuclei split into smaller nuclei and emit neutrons and heat energy.

  16. North Carolina State University Nuclear Plant History of the reactor Cons from a nuclear plant

  17. Nuclear Energy: Pros & Cons*Make a t-chart!* Pros • Create very small amounts of pollution • Very reliable (require little to no outside fuel to operate) • High levels of electric energy can be created at one nuclear energy plant Cons • Radioactive waste (must be monitored for 10,000 years after it is used). • Example: Chernobyl • Where was it? • What happened? • Threat of nuclear terrorism

  18. What is wind energy?  Uses a turbine that is powered by wind. *In the next 50 to 60 years, wind power could be used to create between 5 to 10 percent of the country’s demand for electricity.

  19. Wind Turbines http://www.youtube.com/watch?v=tsZITSeQFR0 Traditional Wind Turbine

  20. Modern Vertical Wind Turbine

  21. Wind in North Carolina

  22. Where are North Carolina’s Wind Turbines? Are there any near Charlotte?

  23. Wind Turbines: Pros & Cons*Make a t-chart!* Pros • Self-sustaining (does not require support from other resources or inputs) • Reliable • Causes little to no harm to plant and animal life on the ground Cons • Not 100% reliable (wind speeds must be at least 16 mph) • Avian mortality (bird killers!) • High initial cost

  24. What is hydroelectric power? Power generated by falling water which drives the turbines.  The water held in a reservoir behind a dam is a form of stored energy that can be released through the dam to produce electric power. The strong water flow that results drives turbines and electric generators.

  25. Hydroelectric Power http://www.youtube.com/watch?v=cEL7yc8R42k

  26. Cowans Ford Dam • Cowans Ford Hydro Station is located in Huntersville, N.C., approximately 20 miles north of Charlotte on Lake Norman. It is the largest conventional hydro station owned by Duke Energy. • Cowans Ford Dam created Lake Norman, the largest man-made body of fresh water in North Carolina. The lake provides a dependable supply of water to Lincoln County and the communities of Davidson, Mooresville, Charlotte-Mecklenburg and Huntersville.

  27. Hydroelectric Power: Pros & Cons*Make a t-chart!* Pros • Completely independent of fossil fuels • Can be shut off immediately (thermal plants can take hours, nuclear plants can take weeks) • Controls flooding • Very few breakdowns Cons • Disrupts natural ecosystems • Plant decay that is created as a result of dams can cause release of greenhouse gases • Expensive to build

  28. NC Energy Brochure • FRONT: NC Alternative Energy Resources • Inside folds: • INSIDE: • Solar Farm-5+ sentence description + picture • Nuclear reactor-5+ sentence description + picture • Cowan’s farm dam- 5+ sentence description + picture • BACK: Pros & Cons of each energy source • Argument of which alternative energy source is best

  29. Exit Ticket! Name the four types of alternative energy sources that are available in North Carolina Give an example of one specific renewable energy facility that is in North Carolina. Describe the pros and cons of one facility you read about. What actions is North Carolina taking to improve energy sustainability?
