Wind Turbine Electricity – Alternative Energy Solution
July 14th, 2009
Wind power is an exceptionally efficient and cost effective power alternative. The wind is an awesome force, and it can put out a lot of raw power to be converted into energy that we can use in our everyday lives. Wind turbine electricity is one of most popular power generators in use today. There are wind farms located in many locations throughout the United States.
Winds are caused by the uneven heating of the environment by the sun, the changes in the earth’s surface, and the spinning of the earth. This is the information that is used to build wind turbines. Since the sun heats surfaces at uneven rates it forms pockets of hot air, and that hot air then rises up and this forces cooler air to rush in to fill the gap. This rushing wind is what creates the power to generate the electricity.
Blades are one of the most important pieces of the equation. Today turbines use blades that are horizontal, and there are usually only three blades. The metal cannot handle more than that as it is too much stress. The blades are made of a lightweight sturdy plastic or fiberglass, they are concave, and somewhat off center for a better angle for catching the wind and spinning the blades efficiently.
The blades connect to a double rotor assembly. The blade rotor connects to the blades and spins as they catch wind. The blade rotor connects to a magnet rotor through a pulley assembly which is on larger turbines or at times directly on the smaller turbines often used for homes.
The magnet rotor does not turn anything it turns around a magnetic alternator which then forms a magnetic field. This magnetic field then goes over the wires of the alternator and an electrical charge is created. The electrical charge that is generated is then carried into a regulator which converts the generated electricity into DC power. A wind turbine actually works just the opposite of the way a fan does; instead of using electricity to create wind, a wind turbine uses wind to create electricity.
Now that you have an explanation of how the wind turbine works, you can understand why it is such a good source of power. Wind has been used for producing energy for many years. It has always been around and it has helped people to do things like saw wood, grind grain, and spin a water wheel.
The technology may be new, but the idea is old. The look has changed, as the turbines are much more aerodynamic and modern looking. This is one of the best power sources for the future, just like it has been in the past.
