1Warm Up1. 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 **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

9Activating StrategyWhat 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?*Extend screen rather than duplicating image on projector in order to view these notes while presenting
10Political 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!
11BIG QUESTION!What types of alternative energy would be most useful and most easily accessible in North Carolina.?Aspects to consider:Weather, climate, Natural Resources
12Write what is in RED and YELLOW!! CORNELL NOTESWrite what is in RED and YELLOW!!
13Alternative Energy in NC Solar EnergyWind EnergyNuclear EnergyHydroelectric Energy
14What is Solar Energy?Uses photovoltaic (PV) panels to convert sunlight directly into electricity.
15North 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 HouseClick on the “Virtual Tour” link (during slideshow) to open a virtual tour of the NCSU Solar House. After opening the page, you can click “enter home” and can take a tour of the home. Click on the “more” tab at the top of the page in order to see how the home usesDaily Tar Heel article on a solar farm in Hillsborough:More info on Hillsborough solar farm:Additional article on NC Solar:More resources:
16Solar Energy: Pros & Cons *Make a t-chart!* Once manufactured, produce no pollutionOnce paid for, provide free energySolar energy production is very quiet, unlike energy created from fossil fuels and other forms of energyConsInitial cost of solar panels is expensiveWeather can affect effectiveness of solar panelsSolar panels only work during daylight hours. This means they can only create energy during daylight hours, and must use stored energy during dark hours
17What is nuclear Energy? 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.“Split” hyperlink:Television commercial using mouse-traps and ping-pong balls (shows how nuclear fission works).“Smaller nuclei” hyperlink: (demonstrates fission more specifically)
18North Carolina State University Nuclear Plant Click on picture of reactor rods (during presentation mode) to open the NCSU Nuclear Reactor website, and then click “History of the reactor” at the bottom of the slide for more historical information. Youtube link is hooked to the “Cons of a nuclear plant.”History of the reactorCons from a nuclear plant
19Nuclear Energy: Pros & Cons *Make a t-chart!* Create very small amounts of pollutionVery reliable (require little to no outside fuel to operate)High levels of electric energy can be created at one nuclear energy plantConsRadioactive waste (must be monitored for 10,000 years after it is used).Example: ChernobylWhere was it?What happened?Threat of nuclear terrorism
20What 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.

23Wind in North CarolinaHave students discuss (1 minute in table partners) where they would place wind turbines if they were creating a new company that was going to sell wind energy.
24Where are North Carolina’s Wind Turbines? Click on map during slideshow to go to live website:Go back to the previous slide and have students analyze if the location of these wind turbines makes sense, based on the wind levels listed on the previous map.Are there any near Charlotte?
25Wind Turbines: Pros & Cons *Make a t-chart!* Self-sustaining (does not require support from other resources or inputs)ReliableCauses little to no harm to plant and animal life on the groundConsNot 100% reliable (wind speeds must be at least 16 mph)Avian mortality (bird killers!)High initial cost
26What 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.
28Cowans Ford DamCowans 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.Link to more information on Duke Energy’s website:Wikipedia:More facts about Lake Norman:
29Hydroelectric Power: Pros & Cons *Make a t-chart!* Completely independent of fossil fuelsCan be shut off immediately (thermal plants can take hours, nuclear plants can take weeks)Controls floodingVery few breakdownsConsDisrupts natural ecosystemsPlant decay that is created as a result of dams can cause release of greenhouse gasesExpensive to build

31Exit Ticket!Name the four types of alternative energy sources that are available in North CarolinaGive 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?
