  1. WIND Power Maeve Riley Shannon Powers Patrick Ryan Matt Minotti

  2. The Basics of Wind Power • Wind power is a pollution free energy source • Wind power is the fastest growing segment of all the renewable energy sources • Wind power can be used in almost 50% of the United States • Almost 1/3 of all the worlds wind-powered electricity is produced in California • There are two types of wind turbines, the vertical axis and the horizontal axis.

  3. WIND TURBINES and HOW THEY WORK • The blades of wind turbines are called vanes • As the vanes spin around they power other machines called generator • Inside a generator there is a large round magnet that spins around on a pole connected to the turbine • Around the magnet there are thousands of coils of wire • Electrical power is produced as the magnet spins around inside the coils of wire using this process, the average wind turbine is able to produce 1.5 Megawatts, or 1 million watts • http://www.nrel.gov/learining/re_wind.html

  4. The origins of wind turbines • Wind turbine develop from windmills, machines used to grind grain and to pump water • The first windmills were developed in Persia in between 500-900 A.D. • These windmills had a vertical axis • The first windmills to appear in Western Europe had a horizontal axis • These windmills had 4 paddle like wooden blades • The first use of the large windmill to generate electricity was built in Cleveland, Ohio in 1888 by Charles F. Brush • During the 1930’s, wind energy nearly disappeared because of low oil prices and government policies favoring the construction of utility lines and fossil fuel plants

  5. How is wind power used • Over the ages, wind energy has been used to: • Pump water • Grind corn • Push sail boats down the Nile • Grinding grain • Provide lift for hang gliders • Fly kites and, • They have been used for base jumping

  6. Where wind turbines are found • Wind turbines can be found in oceans. • The country with the most wind turbines as of 2010 is Australia. • Wind turbines can be found anywhere there is enough room to place them and no danger to the people living there. • Preferred locations for wind turbines have sufficient, constant amounts of wind. • Some factors that limit the production of wind turbines include having to transport them to the area they are needed, and the assembling of the turbines

  7. Advantages of using wind power 1.) Wind is free and with modern technology it can be easily harnessed. 2.) Once the wind turbine is built the energy it produces is pollution free. 3.) Wind turbines take up only a small amount of land, this means that the land below can still be used for other purposes such as farming. 4.) Many people find wind farms an interesting structure to look at. 5.) Wind turbines are a useful source of energy for rural areas that are not connected to the power grid. 6.) Wind turbines are available in a variety of sizes, so they can be used by small villages and large cities.

  8. Disadvantages of Wind Power • The strength of the wind is not constant, which means that there will be times that the turbine produces no electricity • Some environmentalists feel that the countryside should be without these structures • Some people find wind turbines annoying because they are extremely noisy. • While wind turbines are in the manufacturing process some pollution is produced. Therefore wind power isn't completely pollution free. • The largest wind turbine in production can only provide enough electricity for 475 homes while running at full capacity. This means that an entire wind farm is needed to power one community • Wind turbine construction can be very expensive and costly to surrounding wild life.

  9. THE COST OF WIND TURBINES! • Wind turbines under 100 kilowatts generally cost $3,000-5,000 per kilowatt of capacity. • For commercial scale wind turbines the cost may range from 1.2 million to 2.6 million. • Factors that impact the cost of building a wind turbine include the location of the project, the type of the machine and construction contacts. • Wind turbine costs have decreased over the past couple years because of a decrease of the cost of the electricity produced by the turbines.

  10. Oceanic Wind Turbines • Wind turbines are more productive on the ocean because the waters more natural density requires fewer turbines to produce the same amount of power. • Three types of wind turbines have been presented by MIT. These include one that is balanced in the water by a ballast, another that is stabilized by mooring lines, and the one that is the most common today, the buoyancy stabilized wind turbine. • These turbines are shown below

  11. Equipment needed to capture it • Wind turbines need the following parts to work correctly • A rotor • A generator • Transmission • An axis • A shaft • A gearbox • A nacelle • And a tail vane

  12. Fun Facts About wind energy • 50% of USA territory can be used for wind energy. • Although wind energy is a very continent energy source, its not used on its full potential. • In Europe wind energy can be a growing trend. • Wind energy is still not used on a global scale. • Wind energy can stop fossil fuel shortage. • Wind energy theory was discovered in 1919 by German physicist Albert Betz • The first power generating wind turbine was constructed right here in Ohio

  13. Looking to the future • The future for wind energy is looking bright • Wind turbines are rapidly becoming more efficient because per kilowatt costs are dropping due to less expensive equipment • This cost drop is due to the latest technological breakthroughs • Before long, we could see many small scale wind turbines popping up everywhere because they are more cost efficient
