1. What are the positive aspects of wind energy? Explain at least 5 of them.

2.  Identify the world’s largest three wind turbines built and their key characteristics (Location, Power, blade dia etc)

3. Write an equation to find power from a wind turbine. Explain each parameter in it.

4. What is the meaning of this equation

5. For a turbine with 160 m of wing (blade length) produces 7 MW or power. What would be the air velocity to generate this power?
