The first diagram shows the overall structure of a wind turbine and the other one compares the cons and pros of different locations where wind turbines can be installed.
Overall, it is a clever way of generating electricity using wind power and the system is run by a computer to work with maximum efficiency. The overall design of a turbine is simple.
The machine is erected on a tall tower made of steel and has three long blades that are attached to a generator. The blades can be made from wood or fiberglass. The force of the wind turns the blades and the generator starts to produce electricity. For maximum efficiency, the tower is equipped with a sensor that identifies the speed and direction of wind and it is connected to a computer on the ground that controls the direction of a turbine so that it can always look at the wind direction. The wind turbine usually has an output of 1. 5 megawatts.
There are different variations of wind turbines. A smaller one, which produces around 100 kilowatts, can be installed for domestic use. The larger turbines are usually put up in secluded places such as on top of hills and near the shores. If installed at higher levels the turbine makes greater amount of energy due to high speed of the winds but it does not look good. When installed near the coast the energy output is lover, although it does not spoil the landscape.
