<strong>UNESCO</strong> Module 22: Using wind power -----_----- ----------<br />
Siting a wind turbine<br />
When deciding where to site a wind turbine, you need to think about two things:<br />
• Where would be a good place to catch a lot of energy from the wind?<br />
• What will be the environmental impact of the wind turbine?<br />
The diagrams on this page <strong>and</strong> the next page will help you to underst<strong>and</strong> how to<br />
choose a good site. Look at each of the diagrams <strong>and</strong> discuss with a partner what<br />
they tell you about siting a wind turbine.<br />
Using all of these ideas, decide where you might position a wind turbine in your<br />
own locality. If you think this would be completely impossible, explain why.<br />
