How Wind Power Works and Provides Free Energy
One of the best forms of renewable energy is wind power -- it is environmentally friendly, clean, and never-ending! In a way, wind power is the result of solar energy -- the earth's wind starts as the result of the sun heating the earth's surface unevenly, causing wind the rise and fall at different rates in different parts of the world, and the air begins to move about according to physical law, creating what we experience as wind. Wind turbines stand in the wind and this causes them to turn, to spin, and to generate energy. And with your own wind turbine you can take advantage of this free energy to generate your own electricity instead of paying the power company to do it for you -- and their power is often produced from non-renewable, non-environmentally friendly sources.
But before you begin to use a wind turbine, you might want to know how wind power works. The most straightforward way is to imagine a fan going backwards in time: instead of electricity interacting with magnets to turn the fan blades and hence generate wind, the wind turns the fan blades and this interacts with magnets to generate electricity. Put simply:
- wind blows on the blades of the fan
- the fan blades are angled and hence begin to turn
- the axle holding the blades spins
- the generator at the other end of the axle generates electricity
There is usually a gearing mechanism to amplify the motion, thereby generating even more electricity. There is also usually an automatic braking mechanism to prevent possible damage to the whole assembly if the wind speeds gets too high.
Domestic wind turbines generally come in two varieties:
(1) Turbines with a vertical axis
(2) Turbines with a horizontal axis
It is the second type that is generally favored today, and upon which the US Department of Energy is focusing much of its research recently. These usually have two or three blades (those with two blades usually faces away from the wind, and those with three blades usually face into the wind).
You may have seen large three-bladed wind turbines around the countryside, clustered together in what are known as wind farms, and they can produce a lot of electricity -- the larger the blades, the more electricity, in general. Domestic wind turbines are much smaller, and can generate typically 50 kilowatts for home use.
In remote rural areas a wind turbine can also be used to pump water out of the ground, and such locations will often generate electricity using a combination of solar panels and wind turbines. They make use of batteries to collect excess electricity they have generated, and in some cases they can even sell further excess electricity back to the power company!
However in an urban setting a wind turbine will be used as a source of power to supplement the normal grid supply of electricity from the power company. The reason for this is that there is always a chance that there is not enough wind power to generate electricity -- if the wind is much below 8 miles per hour then most wind turbines will not generate power, and the grid will provide the electricity requirements. As the wind speed increases and the wind turbine generates more electricity, the amount taken from the grid gradually decreases.
A general rule of thumb is that the average wind speed should be about 11 miles per hour; if it is lower than that the tower supporting the turbine will have to be taller to catch the higher-speed winds at higher altitudes -- but there are diminishing returns there and if your wind speed is often too low then it may not be worth installing a wind turbine.
Taking into account not only the cost savings from not using grid electricity, plus the occasional opportunity to sell power back to the power company, wind turbines can reduce a home's energy costs by an amount in the region of 50% to 90%, although there are many factors affecting this.
If your home uses 10,000 kWh (kilowatt-hours) of electricity each year, a small turbine of rating between five and fifteen kilowatts should be sufficient for your needs. There will obviously be initial costs associated with installing a wind turbine, but these will soon be recouped -- and you can save more money by building one yourself -- instruction manuals and videos are available for a low price on the internet.
If you install a wind turbine for your home, not only will you be saving money, you will also be saving the earth -- and all because of a little breeze!

Residential Wind Generators Give You Free Power!
Wind power is a fantastic source of renewable energy, and is becoming more and more popular all the time -- it is growing faster than any other such source and associated technology. Wind turbines catch the wind, causing them to turn, driving a generator (or dynamo), and so create electricity. The faster the wind is, and the greater its volume, the more electricity is generated -- so in places where winds tend to be strong, residential wind generators are the right choice to provide you with free power for your home, or for your business.
But don't think that your house has to be perched on a cliff top by the sea with great gusts of wind all day long to be able to take advantage of wind power. Provided the amount of wind your area experiences can typically reach speeds of greater than 8 miles an hour or so, you can still utilize wind energy to supplement your normal grid supply of electricity. You can buy a wind generator and ask a professional to install it, but there are some fantastically easy plans available on the internet for a very small outlay, and even the most modest diy enthusiast can build their own wind turbine in a short time -- and immediately start to benefit from generating their own electricity. Not only will your electricity bills will be lower, but you will be insulated against power cuts, and you can experience the satisfaction of knowing that you are helping to save the planet by using this renewable energy source. What's more, if you do happen to live in a particularly windy environment then you should be able to generate a fair amount of your own electricity -- some people generate so much that they sell their excess back to the power company!
If you want to go down that road, then you should start to think about installing your own wind farm -- this is a set of several wind generators close together on your land (obviously you have to have enough land to be able to do this). You may have seen such wind farms in the countryside, but these are usually commercial ventures and they will use large industrial-strength turbines; yours will be on a much smaller scale. If you have your own wind farm, you live in the right state, and your power company has the appropriate arrangements in place, then you will be able to sell your excess electricity back to them.
Residential wind generators produce next to no pollution, they produce no greenhouse gases contributing towards global warming, and they give you free power -- your initial investment in the turbine will soon pay for itself (especially if you build it yourself).
So by building your own wind turbine you will have a positive effect on the environment and a positive effect on your wallet -- and all because the wind is blowing! Doesn't that sound good?
