  17. 17. Windmill• Windmills are goods for the environment because no harmful solids, liquid or gases are produce.• No need of any fuel or toxic waste is needed.• Wind energy is used to generate electricity by using wind turbines.
  18. 18. How does a wind turbine works The blades catch the wind and turn the rotor which they are joined to.The rotor is connected to the nacelle which houses all the working for the turbine.The rotor turns a shaft which is connected to a set of cogs called a gear box.The gear box is connected to a generator which makes electricity when it turns.
  19. 19. Facts on sand• The tallest sand dune is ISANOE-n-TIFERNE.• Deserts cover about one-third of the earth land-surface.• The actacania desert in South America had no rain for 400 years.
