Wind Turbine Technology

The Wind is a renewable energy resource that can be harnessed and converted to electricity. Windmills have been around for years, but recent technology advancements have made it possible for homeowners to tap into this alternative energy resource. To successfully harness the power of the wind and convert to kinetic energy, which is the type of energy that is produced through motion, into sustainable electrical energy, you will need a wind turbine or windmills. This is perhaps the most efficient way to harness the power of the wind. To generate huge amounts of electric power for commercial purposes, people typically use wind farms. Wind farms are wide open areas with strategically placed turbines to maximize the wind capturing process. Together with other alternative energy sources such as hydroelectric and solar power, these energy systems are a great source of clean energy and can reduce mankind’s dependence on the conventional energy sources like fossil fuels.

The technology behind a wind turbine is not at all that complex. The wind turbine consists of just thirteen fundamental components. You have the foundation, connector to an electric grid, the tower, access ladder, wind control, nacelle, the generator, anemometer, mechanical brake, gearbox, the rotor blade, the blade pitch control and rotor hub. All these thirteen components work together to generate clean and sustainable energy that can be used to power homes, commercial buildings, farms, and other facilities. The best thing about this alternative energy resource is that it is virtually unlimited. Here is how these wind-powered turbines really work: the blades are attached to the rotor which is connected to a low-speed shaft. The low-speed shaft has a gearbox attached at the end. Now when the wind blows, the blades and the rotor will spin which then allows the low-speed shaft to spin, turning the gears within the gearbox in the process. The gearbox is the one responsible for increasing the speed of the spin, which it then passes to the high-speed shaft. Underneath or at the bottom of the high-speed shaft is the generator, which is responsible for converting the kinetic energy, produced by all the spinning, into usable electricity. Wind turbine technology has advanced to the point where we can now install wind turbines in our homes. It is important to note, that the technology has advanced to the point where these turbines are now available in smaller, ‘home sized’ units so that you too can benefit from the power of the wind. We are able to use this wind power, turn it into electricity for our own personal use and then feed any surplus back into the commercial grid. A wind turbine seems easy enough to build, but it’s actually very complicated.

There are many benefits to using wind turbines as an alternative to the conventional power sources. One such obvious benefit is the fact that the wind is a free, highly sustainable and rich resource, unlike fossil fuels which are becoming harder to find. Furthermore, windmills produce clean energy which does not emit pollutants, unlike fossil fuels which produce greenhouse gases. On the consumer side, wind farms generate income that is kept within the community where the projects are situated and are environment-friendly. It is more suitable for remote areas because there will be no obstruction of an air stream. Landowners will receive payments from the government for the use of their land. The best thing about this is, that they still come in different sizes and a lot of jobs is created because of this project.

A huge portion of the property and state taxes are paid for by the wind farms as well. Unlike conventional energy sources like fossil fuels where prices go up and down like a roller coaster, wind power has a fairly stable pricing range that is less likely to increase dramatically. This is because wind resources are not the focus of political issues or conflicts.
