Basic information on wind turbines

The conventional sources of energy are now slowly replaced by the renewable sources such as wind and solar energy. Wind energy does not harm the environment and it can generate a lot of power with the use of wind turbines. Large wind turbines are normally installed in open spaces where there is lots of wind.

Individuals can even install small wind turbines on their home rooftops. The home wind turbines can cost anywhere between $500 and $22,000.
The large elevated wind turbines are placed on a tower that has a height of at least 120 feet. The tower is high so that the wind is not blocked by any objects. When the wind blows it rotates the wind turbines. You may also see several wind turbines in an open space in the countryside. Such a collection of wind turbines is called a wind farm and the energy produced from all the wind turbines in the area is accumulated. The motors are computer controlled and they have top tip speeds of 200 mph. The low torque ripple and high efficiency together contribute towards good reliability.

The blades of the wind mill are normally light grey in color. The tubular steel towers are about 200 to 300 ft tall. The blades of the large windmill rotate at about 10-22 rotations per minute. The beginner makes use of the gear box in order to increase the speed of the generator. Most of the models operate at constant speed however energy collection can be maximized with the use of variable speed turbines. These turbines make use of the solid state power converter to transfer power to the transmission system.

All wind turbines have a protective covering to avoid damage to the wind blades during storms. The blades can also be feathered so that their rotation can be ceased. According to an article in the Grand Rapids Press the wind turbines that are installed in the rural areas of Michigan have a production capacity of 500 kilowatt hours per month. This amount is still not enough to provide electricity to the entire home but it can at least replace some of the energy sourced from the burning of fossil fuels.

By using the power generated from wind turbines the government and the individuals can save considerable amount of money and contribute towards the sustainability of the environment.
