2. OPERATION
A wind turbine is a device that converts the kinetic energy of the wind into electricity. The blades rotate a wind turbine between 13 and 20 revolutions per minute, depending on its technology, at a constant speed or at a speed where variable rotor speed varies depending on the wind speed to achieve greater efficiency.

3. PHASES
To transform wind energy into electrical energy the wind turbine the following steps:
Automatic Orientation: thanks to various household quotes the mill oriented toward the wind to maximize their performance.
Giro blades: the blades begin to rotate with the wind of 3 m / s and give their maximum potential to 11 m / s. If the wind is over 25 m / s shrouds frénanse to prevent overcharging.
Multiplication: Thanks to a multiplier exes become rotate the motor unhas1500 revolutions per second and thus the engine begins to generate power.
Evacuation: energy obtained is transported through cables to the base of the mill and from there to a place where it is transported to where it is used.

4. DIAGRAM
In the following diagram we can see how they run all these steps, since the blades revolve followed by multiplying turns 3 revolutions per second in 1500, after passing through the engine that turns the power cables and finally the transport to use:

5. ELECTRICAL INSTALLATIONS
On the map you can see clearly the areas in which the wind and more productive in Galicia and, therefore, the wind turbines are part of pisaxe. The region of Deza, Tabeirós, Costa da Morte, in the north of Terra Cha Lugo, Ourense limits with Pontevedra and the southern province Ourense. In the community there are about about 120 parks. Hata 11 rub or exceed 40 megawatts of power and among them totaling 775 million already

6. ADVANTAGES Among the many advantages of wind energy we can include:
It produces a lot of energy compared to other renewable energy and is therefore one of the most used
Does not alter the water as do other types of renewable energy, and this is very important.
Easy and clean transport, since it does not use vehicles as refineries or other energy which does not produce toxic gases to the environment.
Helps to reduce the use of fossil fuels that pollute and alter the environment.
It is inexhaustible because the wind is never exhausted.

7. CONTROLLING INSTITUTIONS
ASOCIACION EOLICA DE GALICIA :
The Asociación eólica de Galicia was founded in 1997 by the initiative of ten companies which constitute 90% of promoting wind power in India.
This business union intends to strengthen the presence of the wind sector galician in national and international scene, as well as the creation of a regulatory framework that serious and responsible meets the economic needs of environmental Galicia.
ASOCIACION EMPRESARIAL EOLICA ( ABB) :
ABB is the leading supplier of electrical components, systems and services to the wind industry. A complete portfolio of services for the life cycle reinforces this extensive range

8. And a changing environment for the wind sector, approaching parity in the red, and with governments reviewing their policies and support mechanisms for generation wind, today more than ever and key operating assets wind getting its maximum yield, through a strategy of optimized control and maintenance
GAMESA:
Gamesa in 2004 gave a qualitative leap in the preparation of its annual report and in the form of information and reflect the most significant data of the company. In recognition of this effort, the 2004 Annual Report of GamesaCorporación Technology, presented as integrated memory of the company, has been recognized in 2005 in the category of 'In Accordance' by the Global Reporting Initiative (GRI), the international institution independent who has developed the main standard making memories of corporate social responsibility (CSR)

9. GREENPEACE:
Greenpeace (English green: green and peace: peace) is an environmental organization founded in Canada in 1971, an international, independent economically and politically, it does not accept donations or pressure from governments, political parties or businesses, and self-financing contributions from partners and donors (95% of its funds), as well as through the sale of products with the name of Greenpeace.
IDAE:
The Institute for the Diversification and Saving of Energy, IDAE, and a body under the Ministry of Energy, Tourism and Digital Agenda, through the Secretary of State for Energy, who depends organically.
To contribute to achieving the objectives that have purchased our country in terms of improving energy efficiency, renewable energy and other low carbon technologies constitute the strategic framework of their activities.

10. European Union's contribution
This call has a funding of the European Social Fund of € 30,576,923.
Iberdrola in 2016 made purchases from suppliers Galician worth 66 million, representing an increase of a 73.6% over the previous year.
The manufacture of these structures, which soprtan intend to install wind turbines on the seabed, suppose that the Ferrol estuary over a million hours of work, which implicauns average 900 jobs in the next 20 months. The total amount of these contarte exceeds 120 million and also includes the construction of 126 piles which will be built by the Asturian Aviles in Winder.

11. DISADVANTAGES
Land use: This depends largely of the place of location. However, wind turbines do not occupy all the land, should be approximately 5 to 10 times the diameter of its rotor separation from each other.
Impact on wildlife and habitat: Soen found in higher areas where their impact on wildlife and larger, altered habitats of animals that lived in that area, while also killed birds by these impacts.
Visual impact: These greatly damage the image of the landscape, the current wind turbines are built from the smallest size possible, so that their visual impact is smaller but still it is difficult to minimize.

12. Acoustic: Another problem is the vibration and noise caused by moving the air through the blades generate noise, in any case this noise is not excesivo.Este depends on some factors, the two main ones are:
- The intensity of the wind.
- The distance to the wind turbine.
Take long to build a wind farm, because from the beginning of its construction it takes approximately 5 years.
Your energy can not be stored, so you can itilizarse at the same moment.
Sound can be used in places where the wind is strong and steady which prevents much their placement.
