What’s Wind Turbine Electricity Anyhow ?

by Denzil De Vries

Wind power is the quickly becoming the largest renewable energy platform in the world. You might see these wind turbine generators popping up especially in rural areas. This is a great resource that needs to be tapped into by more companies and individuals at least for partial power use. Wind turbine electricity is very economical, and earth friendly. 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. When you see a modern turbine you will notice that there are only three blades. This is because the metal cannot handle more weight than that as it is too much stress and could break the metal. The blades are typically made of a lightweight sturdy plastic or fiberglass, have a concave surface, and are off center as his gives a better angle for harnessing the wind and it also helps the blades to turn more 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. This is just a crash course in wind turbine technology. It is more involved than some might think. It is more complicated than the average windmill and has greater possiblities for mainstream use. People have used the power of wind for energy use for many years, but it has evolved with new technology. The turbines look futuristic compared to windmills of old with the three blades that are aerodynamic. They do have some similarities, but not the old world charm; however they are much more efficient for the needs of today’s communities.
