Wind energy is a good and viable alternative resource that can be used to generate electricity. But when we see those towering wind turbines, with their huge propellers, we definitely think that it's not something that we can build in our homes. Actually, the truth is there are several residential properties that are now being powered by these looming green energy devices, which prove that it is very much possible to own one of these systems in your area.

While it's not really child's play to build your own wind turbine, it's not too complicated and difficult either. There are things that you should take into account such as wind speed-average wind speed should be about 10 mph-and the size of the operational area in relation to the size of wind turbine you intend to build-average propellers are usually 4 to 8 meters in diameter while towers can be as high as 80 to 120 feet. Some will even include presence of birds and other occasional aerial activities that are conducted within the area that might cause problems in the wind turbine operation.

Once you've determined that your property is suitable for collecting wind energy, the next step you need to make is to find an instruction guide with extensive yet easy-to-follow procedures on how to build a wind turbine. It's important that the manual can explain all technical and electrical aspects in a way that you can easily understand. There are also many online forums and resources where you can find additional help in the wind turbine building process. Often, it is better to ask someone who's actually built one of these devices than solely rely on instruction manuals.

But before you get started, it might help to familiarize yourself with the basic components and structure of a wind turbine. A home wind turbine is composed of propeller or blades, a shaft, electrical generator and tower or support. With enough wind speed, the propeller will turn causing the shaft, which is connected to it at the center of blades, to turn and transfer the mechanical or rotational energy to the electrical generator. The electrical generator mainly made of a coil and magnets, will convert the energy into electric power via the principles of electromagnetic.

The purpose of the tower is not only to support and elevate the whole system to get better access to high-speed winds, but its hollow body houses electrical cables where the generated electricity will flow. This electricity can be used readily to power appliances and other electrical gadgets inside the house. In some systems, they employ batteries to store excess electricity that can be retrieved in periods of low-speed winds.

Depending on the size and the average wind-speed, a wind generator can supply anywhere from 50% to 90% of the total household electricity needs. It can dramatically decrease, if not totally eliminate, the dependence to electrical utility sources which definitely means more money saved.
