the wind blowing moves the blades the blades turning move a rotational shaft the energy produced goes to a generator to turn it into electricity the DC electricity is then stored in batteries a cable drives it to a DC/AC inverter so you can use it for your AC appliances

As you can see, it's an easy process, which is a reason why so many people have had no difficulty in building their own wind generators with a basic understanding on how do wind turbines work. Nevertheless, before starting on your wind generator project, here is some information you might find useful. First, keep in mind that it is a good thing to verify different locations where you're planning to install your wind turbine(s). Checking the strength of the wind and its direction will allow you to find the best and most efficient location for you. Also, it might be beneficial to get this information at different heights, as the wind blows usually stronger on higher grounds. It's pretty easy to adjust the size of the pole holding the wind turbine to fit what suits you best.

Keep in mind that, depending on where you live, the Government might allow grants or some type of tax benefits to people building alternative sources of energy. Making some research on the subject might enable you to build your wind turbines at a fraction of the cost and is well worth the effort of looking for information on the subject. Oh, and look for the information yourself; don't rely only on a friend or neighbor telling you about it, as he might have been misinformed.

Finally, know that a basic knowledge on how do wind turbines work is almost all you need to get started. And the good news is that many DIY kits are available, explaining you in detail how to proceed to build your own wind turbine, making the project easier to do than ever.

A word of caution, however: not all guides are created equal. In order to save you time and money, it's a good idea to check some reviews made by professionals and consumers alike. It'll make the experience much more agreeable, knowing you've chosen the best guide available. So get started today, and you'll find yourself looking forward receiving your electricity bill with a broad smile!

Building your own wind turbine for your home is very easy. There are a lot of manuals available that you can download and for your convenience we have reviewed the top three. See which one is the best at EasyGreenEnergy.info

Wind Turbine Generators.

The easiest way to understand how wind turbines work is to think of a fan operating in reverse ? rather than electricity spinning the blades and thus generating wind, the wind spins the blades, thereby generating electricity.

Breaking it down to it's simplest components, a wind turbine operates as follows:

the wind turns the blades

the blades spin a shaft

the shaft connects to a generator

the generator produces electricity

To expand on that simplification, the turbine's blades are connected to a hub that's mounted atop a turning shaft which runs into a gear transmission box that increases the turning speed which, in turn, is connected to a high speed shaft that cranks the generator. If the wind speeds get too high, a brake is deployed to slow the blades down and prevent damage being done to the system.

There are two basic types of wind turbine:

horizontal axis wind turbines: the kind most commonly in use today and the focus of U.S.
Department of Energy research on wind power, these come in two varieties ?

2-blade horizontal axis turbines spin downwind

3-blade horizontal axis turbines spin upwind

vertical axis wind turbines

The size of a wind turbine will influence its power generating capacity, with the smaller windmills that produce under 50 kilowatts being the type most commonly used to power water pumps, telecom dishes, and homes.

In an innovative advancement known as hybrid wind systems, these smaller turbines are also being used in combination with solar (photovoltaic) systems, rechargeable deep-cycle batteries, and diesel generators to provide storable, on-demand power in more remote, off-the-grid places.

In most residential situations, a wind turbine is used as a supplemental source of power in combination with local, on-the-grid, utility power. There is something called a cut-in speed (7-10 miles per hour), below which the wind turbine will cease to provide an output, and the utility grid provides the structure's power. Above the cut-in speed, the wind turbine kicks in and the grid power supply is proportionately reduced (depending on the structure's energy draw at the given moment).

If the output produced by the wind turbine exceeds the draw from the structure (and/or storage devices, like batteries), the excess power is then sold back to the pubic utility company. Use of wind energy can reduce a residence's energy costs by, on average, 50-90%, though these numbers are influenced by a variety of factors and, as such, can fluctuate greatly.

In a typical residence that uses under 10,000 kilowatt hours per year of electric power, a 5-15 kilowatt wind turbine should more than suffice. This type of system can run anywhere from $6,000-$22,000 to install, depending on a variety of factors, including: its size, your intended application, and any service contracts entered into with the manufacturer.

Being that certain situations (such as in the city) make personal wind power use an unviable option, a general rule of thumb is to consider installing your own wind power system if and only if you pay at least 10 cents per kilowatt hour and your location's average wind speeds exceed 10 miles per hour.

The larger wind turbines have capacities upwards of 50 kilowatts, running these days into the several-megawatt range. These windmills, known as utility scale turbines, can be grouped together and connected to central lines for transmitting and distributing in bulk to the local utility grids that, in turn, sell that power to homes and businesses across the land. These are called wind power plants or wind farms.
