There are however a number of downsides to these small scale micro wind turbines, these are:

Vibration - As wind turbine consists of moving parts, this causes a degree of vibration to occur, which if mounted on the roof, is transmitted through to the building below, causing undue stresses.

Turbulence - Air passing over a building is distorted, resulting in cylindrical air movements. This interferes with the wind turbines normal operation resulting in increased stress and lower energy capture. This can be avoided however, if installed significantly above the roofline; however this is much more complicated and may negate any financial benefits. Or a sophisticated dampening system may be adopted, which separates the turbine from the building structure.

Safety – Turbines installed on roofs are a particular health and safety hazard, with higher risks associated due to their placement within close proximity to occupants.  Their fixings need to be strong enough to withstand high wind levels, and noise levels minimised.

Efficiency – The majority of residents currently live in built up urban locations, which are sheltered areas, and consequently experience high degree of intermittent wind speeds. The average wind speed in a town or city is generally a lot less than for the same turbine in a rural and open location.

Financially these turbines are not currently viable for the mass market, however with increased grants becoming available, this situation may be changing, and if the price is cheap enough, these issues mentioned above may not necessarily be a problem.

The cost effectiveness may be increased through clever use of energy storage from the turbines, such as an electric immersion heating element in a water tank may be used, reducing the impact of intermittent electricity production, and making it more viable a source to meet a home's energy needs.

Although this article emphasises generally negative aspects of wind turbines, it needs to be appreciated, that presuming that are installed correctly, they can provide signficant cost savings, contributing significantly to Homeowners annual energy bill.

Wind Turbine Generators.

We all need to understand that these home made wind turbine plans as alternative power sources are very important. Wind power can relieve the pressure on current energy supplies. It is also a non polluting clean source of energy.

If we hope to retain our natural resources and ensure that we will continue to have energy for the future. A relatively unused source is wind energy. When the wind is blowing we can have a steady flow of electrical energy.

When you build your own wind turbine you are your own energy source and in full control of costs. When you utilize a home made wind turbine plan you will grab wind energy and convert it into mechanical energy which can then be changed into electrical energy.

When you learn how to make your own wind turbineyou will help eliminate or at least reduces the need and dependence on our naturally occurring organic fuels and take us a step closer to relieving the pressure on our environment.

It is relatively inexpensive to have one of these homebrew wind turbines on your property and the cost of startup can be less than two hundred dollars. Small wind turbines for home use can supply electricity for lighting, refrigeration, TV and other household appliances.

Having your own micro wind turbines will allow you to drastically reduce the energy costs utilizing what can essentially be considered no cost electricity.

You will discover a horizontal axis turbine and a vertical axis turbine. The horizontal axis turbines are the more often used and you should think about using these when deciding how to make a wind turbine. The horizontal design places the blade and rotor at the top of a tower.

This design also allows the gearbox and generator to be placed on the ground, making access for servicing more user friendly. This design however may be less efficient because it generates more torque and drag.

You may be asking yourself what is a low cost wind turbine? You can get started under $200. Wind power is safe, clean and renewable. Constructing a homemade wind turbine is not only quite practical, but is also an environmentally friendly answer to suatain today's energy demands.

What is a Wind Turbine Really

Actually, a wind turbine is essentially just a very small windmill. Technology could add various features to the basic model wind turbine, but the underlying concept never changes. The basic parts of a wind turbine are a tower, propeller blades, and a battery where the electricity is stored after it is captured from the rotating propeller blades. Wind turbine energy production is like other means of clean energy production in that, in general, it does not create or add to pollution. Many residential micro wind turbines prove this point. Noise pollution comes from wind turbines. This can be found out by visiting major wind farms. Wind energy is one among 'unlimited' resources, as it uses and exploits the resource that is easily available is in plenty, unlimited and can be refilled almost immediately.

How to Make a Wind Turbine

Once you understand how a wind turbine operates, you can learn to build one. Here's what is required. For less than $150, you can build your own micro-scale wind turbine that is capable of generating about half of the electricity you would use in a typical month. This shopping list is one example.

· A generator or motor
· Pipe Fittings
· The pipe to connect the blades
· Conduit
· Pile of aluminum & wood scrap
· Old extension cord that would serve as a power cable
· Relay
· Other electronic parts
· Battery
· Inverter
· Paint

Building a machine to power your home is daunting for most homeowners. As a matter of fact, one horror story often associated with putting these machines together is the mere thought of assembling it and ensuring that it performs as it should. I do understand these feelings, having experienced them myself. However, be reassured that a person able to follow step-be-step instructions to build a wind turbine could be confident of producing one.

You can slash tons of money off of your annual electric expenditures. You can get a DIY guide on how to build a wind turbine right now.

Save hundreds of dollars in your monthly electricity bill. Learn how to make a wind turbine now.

When renewable energy is discussed, most people picture large structures. With solar, it is a valley full of solar panels glittering in the sun. With wind power, most think of large turbines gracefully twirling in the wind as they sit in valleys or up on hills. As more money is put into renewable energy research, the research results are producing an entirely new spectrum of devices.

With wind power, one of the issues is finding optimal places for placing turbines. Monetarily, this can be problematic. The best wind locations are often located smack dab in the middle of developed areas. Even for areas that are available, the cost of setting up transmission lines for the resulting energy can be obscene. Given this catch-22 situation, many have started working outside the box on wind power platforms.

Oregon State University and AeroVironment, Inc, have come up with a unique solution for the wind power problem. Their idea is to abandon the wind farm idea completely. Instead, they are looking to applications that can be used on a per structure basis. In this case, the solution is micro wind turbines.

Micro wind turbines are essentially wind turbines on a scale of a couple of feet in height instead of thirty or forty feet. The idea is to place the turbines on the roofs of buildings to capture the wind that is often found rushing over the edge of roofs. The turbines are designed to be modular, meaning they can be added to the roof on an as needed basis. This is accomplished by using a track system similar to lighting in a home as the base for the turbines. Depending on the energy needs of the structure, one, ten or 100 turbines can be installed.

Admittedly, a row of little wind turbines may look a bit odd on your average office building. On industrial buildings and warehouses, however, the structures would make little or no difference to the appearance. Heck, they would probably be an improvement. More importantly, the turbines would represent energy independence for many of the businesses using the buildings. Unlike solar, the turbines would generate power during both the day and night, meaning power could be stored in batteries or the utility grid at night to cover high energy use periods during the day.

Micro wind turbines may or may not become part of the solution to the energy issues before us. What is clear, however, is talented people are starting to focus on the subject and come up with innovative solutions.
