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: 1 st & 3 rd Period: page 39 2 nd Period: page 41
Objective: SWBAT evaluate sources of alternate energy in North Carolina LEQ: What actions is North Carolina taking to improve energy sustainability?

1. What types of renewable energy sources do you think are available in North Carolina? 2. Can you think of any renewable energy sources that are near Charlotte? 3. What is the biggest advantage of renewable energy over nonrenewable energy? 4. What is the difference between traditional and alternative types of energy?
NNC 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 BBLAH, BLAH, BLAH! By 2021, 12.5% of North Carolina’s energy must come from renewable energy sources!
What types of alternative energy would be most useful and most easily accessible in North Carolina.? Aspects to consider: Weather, climate, Natural Resources
Write what is in RED and YELLOW!!
Solar Energy Wind Energy Nuclear Energy Hydroelectric Energy
Uses photovoltaic (PV) panels to convert sunlight directly into electricity.
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 Virtual Tour
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
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.splitsmaller nuclei
History of the reactor Cons from a nuclear plant
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
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.
Traditional Wind Turbine
Are there any near Charlotte?
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
The strong water flow that results drives turbines and electric generators. 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. Power generated by falling water which drives the turbines.
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.
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

1. Name the four types of alternative energy sources that are available in North Carolina 2. Give an example of one specific renewable energy facility that is in North Carolina. 3. Describe the pros and cons of one facility you read about. 4. What actions is North Carolina taking to improve energy sustainability?
