Wind Energy Quiz

What is the basic principle of wind energy?

• Converting wind into rotational energy

• Using sails to catch the wind

• Grinding wheat with rotational energy

• Generating electricity from coal or oil

All of the following determines the amount of energy a wind turbine can produce EXCEPT
