1. That’s the Way the Wind Blows By: Grace Frank, Laura Kaiser, Jamie Vaughan

2. Background  The first windmills were developed to help grain-grinding and water pumping(500 A.D.)  Charles F. Brush- Cleveland, Ohio  Dane Poul La Cour

3. How it works  Individual turbines connected to a medium voltage and communications center  Medium voltage is increased to high voltage through a transformer  Transformer- transfers electrical current from one circuit to another

5. Where wind farms are now  California  Ireland  Denmark  Germany  Sweden

7. Location  Most wind farms are located near bodies of water where winds are stronger  United States has planned to construct a wind farm on Cape Cod  Also in California

8. Europe  Denmark- 50% of energy will come from wind farms by 2030  Germany- the biggest wind turbine to be established offshore, and the largest number of wind farms in the world  United Kingdom-target for 10% of domestic energy consumption to be generated from renewable sources by the year 2010

9. Europe Wind Farms

10. Advantages  Wind is free and renewable  Cleans greenhouse emissions  Produces electricity  Quiet  Emission free  Reduces the U.S.’s reliance on foreign oil

11. Disadvantages  Expensive to build  Take up a lot of space  Eye-sore  Kills birds  Obstructs nature

13. Costs  wind power development costs around $1 million per megawatt  Assuming the average wind turbine is rated at 750 kilowatts (kW) in capacity, this means the installation of at least 26 turbines and an initial investment of $20 million dollars.

14. In Conclusion  U.S. facing major energy crisis  Alternative energy sources necessary  Although some argue that it is expensive and obtrusive, overall its benefits outweigh its disadvantages  Despite its unattractive appearance, isn’t it better than smog?

15. In Conclusion
