How To Build A Windmill For Wind Generated Electricity

Learning how to build a home windmill to generate some or all of your electricity needs has finally become practical. In the past, the primary way to benefit from wind generated electricity was to purchase a commercial wind turbine and have it installed by professionals at a cost of $10,000 - $20,000 and up. Today with inexpensive technology and improved guide books it is possible to do it yourself for as little as $200.

How a wind turbine generates power and sends it to your house is really pretty simple. The wind is caught in the blades which turn an electric motor backwards generating a direct electrical current. This energy is then stored in batteries. When electricity is needed it is passed through a small electrical device and converted from direct current (DC) to the alternating current (AC) that your appliances require.

The main components of a typical home windmill

1. The Windmill - This often consists of 3 blades about 4 feet in radius attached to a hub that is also connected to a DC electric motor. These items are suspended vertically by a tower that is at least 8 to 12 feet tall. A tail fin is attached to the back of the motor unit in such a way that it will pivot the blades to keep them facing the wind.

2. Battery Bank - This a group of one or more deep cycle batteries that store the generated power for later use.

3. Inverter - This clever device converts the direct current (DC) that comes from the stored energy in the batteries into alternating current (AC) that most household appliances require.

4. Charging Controller - This electronic device prevents the batteries from being damaged from overcharging.

5. System Meter - This piece monitors how much power is available from the battery bank and how much power is being used at any given time.

One of the conveniences of making your own windmill is that you can keep the system as simple or as complicated as your budget and skills allow. A simple system would not tie in with the electrical grid from the power company to your house. Instead it would enter your house separately and not connect to the house wiring. The power would be specifically designated for just certain appliances. This saves the cost of hiring an electrician to do the hook up but eliminates the possibility of selling excess electricity back the utility company.

A more complex system might merge the windmill electricity to that of a set of solar panels and to the power grid coming into the house from the power company. This configuration not only insures a continual supply of energy on windless days but, also provides for the exciting possibility of selling excess power back to the electric company.

Building a windmill is not all that complicated but it does require a good set of illustrated plans written by someone with direct hands-on experience and great sources for inexpensive and free materials. Links to reviews of some popular windmill plans are available in the author’s box below.

Now you have no excuse for not cutting your electric bill while improving the environment. So why not have some fun and learn how to build a windmill?

This is an instantly downloadable step by step manual for inexpensively building, (as low as $200 each), your own electricity generating solar panels and windmill.

Earth4Energy Has Earned Our Highest Rating!

This is an instantly downloadable step by step manual for inexpensively building, (as low as $200 each), your own electricity generating solar panels and windmill.

After I purchased the Earth4Energy eBook I was able to read through the entire manual in one evening. This practical, hands-on manual is designed to quickly get you started building. No unnecessary technical jargon is offered.

It is very specific with lots of helpful and easy to understand diagrams and photos, (with only a few exceptions). The information is very specific and yet allows for adjustment if the parts you obtain vary from the author’s example.

At the time of this review, I tracked down the recommended used and free parts sources and found them to be easily available as promised.

I like the fact that the Earth4Energy manual is constantly being updated. Refinements and tips are available free on the Earth4Energy website to anyone that purchases their manual.

UPDATE: The Earth4Energy Company has begun to produce a whole series of short and focussed videos that show critical details for building windmills and solar panels.

Some of the initial videos show the essential methods and tricks for easily soldering electrical leads to the individual solar cells as well as exactly how to connect all the cells in an entire panel. These and future videos on windmill construction are available on a special "members only" webpage that is available at no extra charge to anyone that buys the main eBook.

I have increased this program's rating from 9.0 to 9.7 because of these instructional videos. Earth4Energy is now my highest rated program.
