WIND ENERGY

It is associated with wind energy.Energy which owns is the kinetic energy of the wind, which we use in the mills in sailing...

It can be transformed into mechanical energy in the molibos of wind or sailing boats and electrical energy in wind turbines.

Wind energy is obtained by the wind, i.e. using kinetic energy generated by effect of the air currents.

The term wind comes from the Latin Aeolicus, belonging or relating to √Čolo or Aeolus, God of the wind in Greek mythology, and therefore, belonging or relating to the wind. Wind energy has been used since ancient times to move boats powered by sails or operate machinery Mills to move their blades. It is a type of green energy.

The wind, a cheap and clean source of energy, would begin to be taken soon in our country. This is realised through the construction of a large number of mills, which would generate electricity on the basis of the so-called wind energy.

Obviously, they would not be mills as those sturdy and large blades of which we hear the stories, but rather long and modern metallic structures of high efficiency and productivity, such as those already abound in developed countries. In addition, in the strict sense, nor would be Mills, because they grind not nothing, but rather of wind turbines.

One of the companies with plans is renewable energy Peru. It has just received the authorization to carry out feasibility studies of Central wind Casma I, which will be located in the province of the same name, region, and would possess the considerable power of 100 MW.

But this is not the only project. There are other two even larger. Huayra Kallpa company has also received authorisation for his studies of wind plants Bella Union (in the province of Caravelí, Arequipa) and Punta balconies (Talara, Piura). Each one will have an installed power of 200 MW.

It is thus three important, comparable to a hydroelectric medium size enterprises. Hopefully studies confirm the goodness of the projects, in about two or three years more us, to travel through these areas of the country, the beautiful image of a huge, slender and efficient turbines wind generating part of the electricity required by the country.
ADVANTAGES

or clean
or Simplicity applied principles
o Direct conversion
or becoming competitive
or it is a type of renewable energy which has its origin in atmospheric processes due to the energy that reaches the Earth from the Sun and sousa.
or it is a clean energy as it does not require a combustion which produces carbon dioxide (CO2), and produces no emissions and polluting waste.
o while not in all the places it can be used as sole source of electrical energy, their inclusion in an interligado system allows, when the wind conditions are good, save fuel at thermal power stations and/or water in the reservoirs of hydroelectric power stations.
or being integrated interligados systems of electric power, allows savings of fossil fuel or water stored in dams.
or You can install in areas unsuitable for other purposes, e.g. in desert areas close to the coast, in arid and steep to be arable slopes.
or You can live with other uses of the land, e.g. Meadows for low as wheat, corn, potatoes, sugar beet, etc. crops or livestock use
o current turbines are of low speed rotation, the problem of collision with the birds is being reduced.
o Creates jobs in areas where builds and assembly plants.
or Wind is a strong alternative to climate change that does not produce greenhouse.
or Its installation is fast, from 6 months to a year.
or Use combined with other types of energy, usually solar, allows self-powered homes, thus ending the need to connect to networks, exceeding 82 hours, autonomies and can achieve without food from any of the 2 systems.

DISADVANTAGES

o Intermittence of the winds
o Geographic dispersion
o Environmental impact on ecosystems
o Generation of interference
o Technology developing
o Difficulty of storage

OPERATION OF AN EOLIC ENERGY

Currently used, above all, to move wind turbines. These wind moves a propeller and by means of a mechanical system is turning the rotor of a generator, normally an alternator that produces electric power. That its installation is cost-effective, usually grouped into levels called wind farms.
