That’s the Way the Wind Blows

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
How it works
Individual turbines connected to a medium voltage and communications center
Medium voltage is increased to high voltage through a transformerTransformer- transfers electrical current from one
circuit to another
Where wind farms are now
California Ireland Denmark Germany Sweden
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
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
Europe Wind Farms
Advantages
Wind is free and renewable Cleans greenhouse emissions Produces electricity Quiet Emission free Reduces the U.S.’s reliance on foreign oil
Disadvantages
Expensive to build Take up a lot of space Eye-sore Kills birds Obstructs nature
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.
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?
In Conclusion
