1. Wind Energy Haley Campbell, Alex McManus, and Emma Pollick Pd. 2

2. Our group has the topic of wind energy. Wind can be used to do work. Wind can be converted into two different types of energy. -Mechanical Energy -Electrical Energy Wind is a very “GREEN” resource.

3. ~How It Works~ Blowing wind spins the blades on a wind turbine---just like a large toy pinwheel. The blades of a wind turbine are attached to a hub that is mounted on a turning shaft. The shaft goes through a gear transmission box where the turning speed is increased. The transmission is attached to a high speed shaft which turns a generator and makes electricity. In order for a wind turbine to work wind speeds

4. Where is Wind Energy Most Efficient? Wind Energy is Most efficient in: Germany! In 2007, Germany produced 22,247 MW of Wind Energy. In 2006, Germany produced 20,622 MW of Wind Energy. In 2005, Germany produced 18,415 MW of Wind Energy.

5. Economics of Wind Energy In 2004 wind energy cost one-fifth of what it did in the 1980's. The cost of the commercial and the turbines from 1 to 2 million per MW of nameplate capacity installed.

6. Environmental Effects Wind power consumes no fuel, and has no emissions directly related to electricity production. The wind energy operation does not produce carbon dioxide, sulfur dioxide, mercury, particulates, or any type of air pollution. WIND ENERGY IN NO WAY HARMS THE EARTH!!

7. Penetration Wind Energy Wind Energy ''penetration'' refers to the fraction of energy produced by wind compared with the total available generation capacity. There is no generally accepted ''maximum'' level of wind penetration. The limit for a particular grid will depend on the existing generation plants, pricing mechanisms, capacity, for storage or demand management, and other factors.

8. Intermittency and Penetration limits Electricity is generated from wind power at several different timescales: from hour to hour, daily and seasonally. Electrical generation and consumption must remain in balance to maintain grid stability.
