There are benefits to fitting your home with a windmill to provide electricity. But before you can realize your benefit to save you must first know a few things.

You must live in an area where you have the wind power available to turn the turbine, you must also live where placing the tower to hold your turbine is not regulated, and you must know how much electricity you are going to use.

A typical home in the United States uses about 800 kilowatt-hours a month in electricity and depending on the wind speed in the area this would require a generator rated somewhere between 5 and 15 kilowatts. These sized windmills normally have a 23 foot span on the blades and are mounted on a tower somewhere between 80 and 100 foot.

Wind turbines are not small devices and are not recommended for urban homes or small-lot suburban homes. It is recommended that you have at least an acre of ground before considering installation of wind turbine and tower combination.

The turbine should be installed at least 20 feet above any obstructions on your property such as trees and buildings. As tower height increases wind becomes faster and less turbulent. A somewhat rule of thumb is that if you increase tower height by 20 feet you can boost the output of your turbine by approximately 36%.

As there are many companies that produce wind turbines and their efficiencies are different one would need to research them carefully before purchasing and installing. Most states in the United States do offer tax credits if you install wind power and the federal government did pass regulation that requires local power companies to let you install a wind generator and requires them to pay you for any excess you produce.

It is possible to purchase a wind turbine and tower and install it for around $7000. If you have an average wind speed of 12 miles per hour you would produce about 400 kilowatt hours of electricity per month. Here where I live that would lower your electric bill approximately $40 per month or $480 per year. Which means my system would pay for itself in 16 years. Then it would be free power.

If I produced my total electric usage a month of 840 kilowatt-hours my system would pay for itself in 8 years. Now you also have to consider that if I produce any extra power the utility has to buy it from me and the price they pay here in Tennessee is 0.15 cents per kilowatt hour. So 1000 kilowatt hours per month would save me $84 per month and the extra 160 kilowatt hours I sold to the utility would make me receive an income of $21 per month saving me a total of $1260 per year or a four year recoup of my initial investment.

We all know for sure that taxes and utilities will continue to increase in the future. By investing in wind power now one can have his investment paid for and when the golden years of retirement come not have to worry about the cost of electricity.
