1. Wind Power Paulo César Ribeiro Marciano PET Elétrica Faculdade de Engenharia - UFJF

2. History Humans have been using wind power for at least 5,500 years to propel sailboats and sailing ships. Windmills have been used for irrigation pumping and for milling grain since the 7th century AD.

3. The windmill for grinding grain The wind power for pumping water

4. Functioning Currently we use the wind to move turbines - large turbines placed in areas of high wind. These turbines have the shape of a windmill or a windmill.

5. Wind energy The most comprehensive study as of 2005[13] found the potential of wind power on land and near-shore to be 72 TW, equivalent to 54,000 MToE (million tons of oil equivalent) per year, or over five times the world's current energy use in all forms

6. Wind farms A wind farm is a group of wind turbines in the same location used for production of electric power. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore.

12. The world's largest wind farm Located on the coast of Kent in southern England The turbines have a height of 115 meters 100 turbines capable of producing 300 megawatts. Investment of 914 million euros.

13. In Brazil Brazil has a potential wind farm 143,000 MW Since the inception of Proinfa, Brazil's wind energy production has escalated from 22 MW in 2003 to 602 MW in 2009, as part of 36 private projects. Today, there are 50 wind farms in operation in the country, according to the Brazilian Wind Energy Association (Abeeólica)

14. The wind turbines in Brazil generate only 0.87% of all energy in the country, the equivalent of a 1 gigawatt. There are at least 35 parks under construction in the Country

16. Developing these wind power sources in Brazil is helping the country to meet its strategic objectives of enhancing energy security, reducing greenhouse gas emissions and creating jobs. The potential for this type of power generation in Brazil could reach up to 145,000 MW. Largest Wind Farm in Latin America – Osório – RS.

17. The sun sets behind a wind farm near Montezuma, Kansas. The 170 turbines of the plant have the capacity to generate enough power for 40,000 households.

18. Positive factors Not exhausted Clean energy Widely distributed globally If used to replace fossil fuel sources, assists in reducing the greenhouse effect. Renewable Speed ​​ of deployment, even in large-scale

19. Negative factors Noise Visual pollution Property devaluation on the surrounding the giant windmills Geo change in environmental components (water, soil, morphology, topography and landscape).
