Wind Energy: A Real Alternative? Lesson Overview In this lesson, students will analyze whether wind energy is feasible. The lesson will have the students explore the following: How is wind used to create electricity? How much does wind energy cost? Analyzing the average wind velocity in their area with the aid of an online calculator, can typical homeowners create their own energy, or do they have to rely only on large utility companies to provide it? Grade Level Grades 6-8 (middle school). This lesson can be easily be modified for grades 9-12 (secondary school) by examining each of the above topics in more detail. Time Required Teachers should be able to conduct the lesson in one or two classes (depending on the activities chosen).

Main Objective Students will examine wind power as an alternative source of electricity utilizing a renewable resource. They will examine samples of current wind farms which use large, expensive turbines to produce energy for the electrical grid, usually owned and controlled by a public utility, such as SaskPower. Each student will have the opportunity to examine the feasibility of using small wind power as an alternative to purchasing power from the grid. Learning Outcomes By the end of the lesson, students will be able to:  Research and explain how wind is utilized to produce electricity as a renewable resource, as opposed to using non-renewable resources, such as coal or oil.  Briefly outline the benefits of wind energy for the residents of Saskatchewan  Calculate the feasibility of producing electricity from a small wind turbine in their own community.  Extension: Briefly describe the extent to which SaskPower utilizes wind power within the province of Saskatchewan and exploring similar projects in other provinces The Lesson The Lesson Teacher Activity Student Activity Introduction Ask: “How important is electricity in our lives?” Working alone or in pairs have students How will the Create master list of objects that use electricity lesson open? brainstorm and list from student responses.

Use the handout “How a Wind Turbine Works” to introduce what a wind turbine is and how it produces electricity. The supply of wind is vital to being able to use a turbine. Group activity: With a data projector calculate the number and size of turbines needed by your school. Go to: http://www.smallwindenergy.ca/calculator/home.p hp. Follow the instructions to get the results of the calculator (you will need your school’s postal code and average monthly utility costs). Go to http://www.windatlas.ca/en/maps.php to get a detailed map of your area – use the zoom tool to see a larger version of the map. (Students can use this for their individual homes as well). Follow up with an example of a school which has installed its own wind farm to produce electricity in Spirit Lake, Iowa (see website under resources). Conclusion Having students, working as a team, create a short creative presentation on why using renewable resources (such as wind energy) is better than depending on fossil fuels or nuclear power. This can be done as a skit, poster, collage or audio- visual presentation.

Lesson Extension Students can explore the various forms of renewable energy sources to compare their costs with wind power. Have them develop a compare/contrast chart with at least one other type of energy creation to show how wind power ranks against it.

STUDENT ACTIVITY SHEET

Why is Wind Energy Important?

We use large amounts of energy every year. Canadians use more energy per capita than any other group of people on the Earth. We should be concerned about the sources of our electricity. Burning coal or oil to make electricity creates a large amount of pollution. Energy from a nuclear power plant raises issues about what will happen to the radioactive waste materials. More and more Canadians want to get their energy from renewable sources, such as solar, water and wind power.

Fast Growing The International Energy Agency estimates that as of 2001 all renewable energy sources (hydro/water, solar, combustible wastes and waste renewables, geothermal and wind) comprised 13.8% of the world’s energy supply. Of that, only 0.0026% was wind power. Wind power, though a very small percentage, is one of the fastest growing methods of all electricity production. Since 1971 energy from renewable resources has grown only 2% per year, while wind production has grown on the average 52.1%! Advantages of Wind Energy  Wind energy is free.  It is a renewable energy resource.  There is no pollution produced.  Wind power can be used in remote areas far away from other sources of electricity.  Wind power can be produced along with other renewable energy resources such as solar energy.

Disadvantages of Wind Energy  Wind turbines need a regular, reliable source of wind.  Wind speed changes. If the wind speed is too fast or slow then electricity is not produced.  When the wind does not blow electricity is not produced.  Wind farms have many large windmills that stand up to 10 times taller than most houses, which many people do not like to see and they may create a steady swishing noise which annoys people living nearby.  Wind turbines are very expensive to buy and maintain.  There needs to be some form of energy storage, like batteries, when no electricity is being produced.

Questions: 1. What problems are created when producing electricity by burning fossil fuels in power plants?

2. From the list above which is the most important advantage to producing energy from the wind? Which is the most important disadvantage? Explain your choices.

3. Bonus: How can wind energy production increase by 52.1% since 1971 and still only be 0.0026% of all renewable sources of energy? THE CANADIAN ATLAS ONLINE SASKATCHEWAN – GRADES 6 TO 8 www.canadiangeographic.ca/atlas

STUDENT ACTIVITY SHEET

How a Wind Turbine Works

A wind turbine creates electricity. The wind turns the blades, which spin a shaft, which connects to a generator to make the electricity. The electricity is sent through transmission power lines to a substation, then on to homes, business and schools. In larger turbines a computer will determine the wind direction and will keep the blades pointing into the wind. The computer also determines the most efficient angle (or pitch) for the blades. For smaller turbines the direction is determined by a tail fin and it will turn to face the wind like a weather vane. When the wind becomes too strong during a storm the large wind turbines have an emergency shut-off and will stop rotating to protect the blades and the equipment inside.

The diagram below shows the main parts inside a wind turbine: THE CANADIAN ATLAS ONLINE SASKATCHEWAN – GRADES 6 TO 8 www.canadiangeographic.ca/atlas
