Alternative Energy Source

What is WIND ENERGY ?

Wind energy wind up the movement of the air flow (kinetic) energy. A portion of this energy is converted into useful mechanical or electrical energy.

What is WIND ENERGY ?

Based on the utilization of the power of wind to start very early ages. The first use of wind power can be displayed as a form of sailing ships and windmills. Then, grinding grain, pumping water, cutting of trees for the benefit of wind power. Nowadays more and more used to generate electricity.

What is WIND ENERGY ?

Fossil, nuclear and other methods, the atmosphere is released harmful gases, the gases cause air and water pollution. In order to obtain wind energy, none of these harmful gases released to the atmosphere, so wind energy is clean energy, noise pollution is caused by a single. Propellers sounds back out today greatly reduced.

Situation in the World

Wind power in the world has become increasingly one of the most used among renewable energy sources. Although the rate of use is in the world today, it is predicted that the12% of world electricity demand will be met from wind power by 2020.

Situation in the WorldAccording to 2013 Half-year Report of

The World Wind Energy Association

The total capacity will reach 318,000 MW in the world. The top wind markets 2013 are China, Germany, India and

the United Kingdom.

Benefits at a energy sources

• A clean source of energy,• Renewable source,• Installation and operation of wind plants is easier than other plants,• Energy production costs are low,• To increase reliability,

• Regional so people can produce their own electricity.

Wind turbines

Wind turbines, wind energy is kinetic energy at first and then the electrical energy into mechanical systems. A wind turbine tower, generators, transformers and speed (gear box), consist of electrical and electronic components and propellers.

Wind turbines The kinetic energy of the wind into mechanical energy

converted into the rotor. Speeding up the movement of the propeller shaft speed is transferred to the generator housing. Obtained from the generator by means of electrical energy stored in batteries or directly delivered to the recipients.

Wind turbines

The size and type of wind turbines in use vary, but are usually classified according to the axis of rotation. According to the rotation axis wind turbines "Horizontal Axis Wind Turbines" (YERT) and "Vertical Axis Wind Turbines“ are classified into two categories.
