2. Alternative energy source  Our alternative energy source is wind power. An alternative energy source is a source that dose not harm the environment and is renewable

3. How it Works  The blades in the turbine spin and that turns a gear. The gear turns other gears that turns the generator which creates energy.There is also a gear that turns it into the wind.

4. Disadvantages  Some pollutants are given off into the atmosphere in the creation of a wind turbine.  Many people feel that wind turbines are unsightly and that they should not disrupt the natural beauty of landscapes.

5. Advantages of Wind power  Wind is free and in abundance.  The costs for wind turbines are only initial costs.  The space which a wind turbine takes up on land is very small as the moving parts are quite a distance above the ground.  Wind turbines produce energy with minimal damage to the worlds environment and produces "clean power".

6. Why we chose wind power.  It’s renewable and will definitely be here forever.  We don’t have to pay for wind.  There also non-polluting and efficient.  It helps reduce Global Warming.  The wind turbines can effectively generate energy for free as long as wind is available.

7. Conclusion  Wind is free but fossil fuels aren’t.  We will always have wind but fossil fuels will eventually run out.  Once the wind turbine have been built the power is free were as fossil fuels aren’t.
