Wind energy
Intensive and persistent power of wind flow we can use for almost anything due to aerogenerator. Fascinating is a forced movement of the propeller, that generates electricity.
Wind energy is the indication for the technology, that is interesting in using wind as an energy source.
The advantages of wind power plants are low operating costs and the energy source (wind) is free and inexhaustible. Wind power station produces clean energy without waste and gaseous emissions and heat waste does not burden the environment. The requirements on the area site are minimal.
The principle of wind power(1).png)
Aerodynamic forces, that are acting to the rotor, which converts by turbine wind energy to mechanical energy. Then it becomes due to a power generator source of electrical energy. Along the rotor arise aerodynamic forces. Leaves of generator must be specially shaped profile, that is very similar to aircraft wings. With the increasing speed air stream rising wing forces with the square of wind speed and the energy produced by a generator with cube. It is therefore necessary to ensure effective and rapid control of operating output of the rotor so as to prevent mechanical and electrical overload wind power station. Operation of wind power is automatic.
In long-term wind power plants have a chance to become one of the sources, which will replace the capacity of coal-fired power plants. But themselves can never fully replace the great resources. According to study of Euroenergy installed capacity of wind power plants reach a maximum of 1044 MW in 2010.
