Most people who sell wind turbines say that wind turbines are highly recommended machines that can help a person utilize free wind to make energy. However before buying a wind turbine it is important to know “how do wind turbines work” and how electricity is created since an informed consumer can protect themselves from sellers who claim to sell products that work but actually do not. The following paragraphs will help you decide for yourself if wind turbines are genuine by explaining how they work.
Wind turbines work on the concept of utilizing windpower and solar power to create renewable energy. These wind turbines are actually large propellers that are mounted to towers that create energy when the sun heats up the atmospheric air. Wind is created when the sun heats up some patches more than the others, and the cooler patches descend to take the place of the warmer patches. Wind turbines utilize this air and the propellers generate either mechanical energy or electricity.
Listed below are a few parts of wind turbines and will help you understand how do wind turbines work.
· Blades – Blades work when the wind blows over the blades and the blades then lift and rotate.
· Controller – This piece of equipment starts the wind turbine when the wind speed is at about 10 - 16 MPH and stops when the wind speed reaches 55 MPH to avoid any damage to the turbine.
· Generator – Generates 60 cycle AC electricity.
· Towers – Towers are made of tubular steel, steel lattice or concrete and taller towers help generate more electricity since the wind rate increases with height.
· Yaw drive – Upward turbines require a yaw drive which is used to position the rotor facing into the wind when the direction of the wind changes. While learning about how do wind turbines work it is important to remember that in downward turbines, the wind moves the rotator downwind and a yaw drive is not required.
Wind turbines that are available in the market are either horizontal axis machines or are vertical axis machines, with the horizontal axis machines containing 2 or 3 blades that face the wind. Individual wind turbines that generate lesser than 100 Kilowatts of electricity are smaller and meant for single homes. Commercial wind turbines on the other hand can be as large as a foot ball field and can generate enough electricity to power thousands of houses.
A good question to pose to the seller of the wind power system you are looking to purchase is, “How do wind turbines work?” This will help qualify a good wind turbine dealer.
