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.
 The windmill for grinding grain
The wind power for pumping water
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.
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
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.
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.
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)
 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
 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.
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.
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
Negative factors
 Noise
 Visual pollution
 Property devaluation on the surrounding the giant
windmills
 Geo change in environmental components (water, soil,
morphology, topography and landscape).
