The document discusses how wind energy works, including how wind turbines generate electricity from wind power and how wind is formed from uneven heating of the earth by the sun. It notes that wind energy has advantages of being renewable and not polluting but also has disadvantages like being expensive, noisy, and not producing energy when there is no wind. Resources for learning more about wind energy are also provided.

1. Wind

2. How do people use the
wind to make energy?
· Wind can be used to generate
electricity
· This electricity is produced by a

4. How does a turbine generate electricity?

use wind to make
electricity.

5. Advantages of wind energy
·They do not pollute the
environment because they do
not us as much fossil fuels
·It is a type of renewable
energy (power can be
produced as long as there is

6. Disadvantages of wind energy
·They are expensive
·They make a lot of noise
·You need wind. If there is
no wind, no energy is
produced.
·Wind mills need a lot of
