2. INTRO I am going to talk to you about wind turbines. I will mention how they work, where they were originally from, and why they are used. I hope you like it.

3. A wind turbine converts the energy of wind into kinetic energy. Wind is just air in motion. It is caused by uneven heating of the earths surface by the sun, because the earths surface is made up of all types of lands. The energy in the wind turns 3 propeller blades around a rotor. The rotor is connected to a main shaft, which spins a generator to create electricity.

4. Wind Turbines have been very useful in providing homes and businesses with clean and renewable energy.Wind power helps decrease global warming. If we use wind turbines we won’t have to worry about GLOBAL WARMING!!!

5. Wind Energy has been the fastest growing energy source in the world since 1990, but it has been achieved with wind turbine technology since 1997. The wind turbine company has been developing a 2 blade wind turbine.

6. 1. Wind is just air in motion. How is this caused? 2. How do wind turbines work? 3. What have wind turbines been useful for? 4. What does wind power decrease? 5. What has the wind turbine company been developing?
