DIY Small Home Wind Turbine Generators – Researching the Right Site Location and the Right Tower

Tue, 27 Jul 2010 07:32:25 +0000

Are you getting frustrated with rising energy costs? Have you been thinking about building a small residential wind turbine? You're not the only one. Given the increased price of conventional power sources, many people are considering the benefits of making their own wind generator or turbine. Before embarking on this venture however, there are a few things you should educate yourself about. Determining how a home turbine works, what you'll need to build one, and where to get those items from ahead of time will save you money, time and frustration. It is important to make sure you understand the basics of a home wind power generating system long before you get started. Familiarizing yourself with the individual components that make up a home wind power system will decrease the likelihood that you will lose time and money to problems that could easily have been avoided by doing your homework ahead of time. One of the first and most important things to consider is where you're going to build your turbine. Of course you need to have the room on your property, and in addition you need to determine the most optimal spot in terms of being able to capture the largest amount of wind power. Typically this will involve being far enough away from any obstacles that could block wind flow to the turbine. Another important aspect of locating a site for your wind generator is that the location must meet the local zoning requirements of your town or municipality. You don't want to skip checking on zoning rules and end up making a mistake that will cost you money and time. So first, contact your local or state zoning agency and then within those confines determine the optimal site in terms of wind and the features of your available property. The next thing to consider is the tower that will support your wind turbine. The tower needs to be tall enough to place your turbine in wind that is strong enough to generate sufficient power and the higher you go, the more power you'll generate. However the higher you go, the stronger your tower will need to be and the greater the cost will be. Remember you want your wind turbine to remain standing even in the face of hurricane force winds. Another reason to limit the height of your tower is that as you go higher the increase in wind power won't pay off for the increased cost of your tower. The tower can end up being the most expensive part as it the biggest. Thus you can see that it makes good sense do your homework ahead of time. This is true whether you build your own and purchase a tower. Keep in mind that if you build your own, there may be liability issues so consider this drawback and weigh it against any extra cost of simply buying a manufactured tower. Getting started on building your own wind turbine system can seem daunting but with proper preparation you can avoid running into trouble by addressing issues such as those discussed above before you begin.

Wind Turbines, Clean Energy for a Cleaner Environment

Mon, 26 Jul 2010 08:58:21 +0000

One of the main reasons for using wind turbines is that natural resources are not everlasting and every one under this sky should think on how to protect the environment for the generations to come. Learning how to avoid pollution can result in a more healthy society. When it comes to look after the environment, everyone should begin from himself by trying to keep the air and water pure, clean and healthy. So instead of using electricity to make wind, we can use wind turbines to make electricity. Generating electricity from wind sources is extremely cleaner than generating it by using fuel. No pollution, no dangerous waste that kills fragile organisms, nothing deadly whatsoever.

Wind turbines are those rotating things that produce energy when blown by wind,The wind turns the blades, which roll a shaft joined to a generator that gives electricity. The most familiar types used today are the horizontal axis turbines; they are significantly more efficient and are able to produce fairly large amounts of energy in comparison to other types of renewable power. Horizontal axis turbines need to be pointed directly at the wind.

There are various sizes and power ratings of wind turbines. the best location for wind farms is on ridges, hill-tops , near the beach, and even being set up in areas of unused farmland that are almost without trees, where they can catch the wind . Small wind turbines can also be useful on boats, the movement of the ship will gather enough breeze to let the blades turn even when winds are low, making them an extremely dependable source. By using wind power to generate electricity, you can reduce air and water pollution and ease global warming. Wind energy produces no emanations, needs no fuel and the cost of the electricity produced is fixed over time.

Wind turbines do not make annoyance. The development of wind farm technology over the past was linked to high levels of mechanical noise, but newly developed wind turbines operate quietly. They are now becoming popular for small and large applications.

Who Else Wants To Know About Alternative Energy

Sat, 24 Jul 2010 19:13:45 +0000

It is estimated that our natural resources will be completely depleted within the next 150 years. It is because of this that we as a society need to be actively searching for sources of alternative energy.
Alternative energy, whether it is used to replace fuels such as coal, or to reduce our reliance on petroleum based fuels; alternative energy is one of the most important issues facing society today.
The two most common types of alternative energy are:
* Wind power
* Solar power
Both of these alternative energy sources are harnessed from natural resources, and as such are completely free. Only the equipment and technology cost money, and over time as we advance the costs should be reduced.
It is these free sources of alternative energy that we should be pursuing with the most fervency, so that, eventually, energy can be available to all regardless of income. Below we will take a look at these two most common sources of alternative energy.
Wind Power
Wind power, while a free source of alternative energy, would be the most costly type of renewable energy to power our nation. This is largely in part to the fact that we must first place wind turbines across the country, in enough numbers to provide electricity to communities nationwide, even in areas where the wind velocity is not as strong. The cost of building enough of these turbines to harness the wind's alternative energy would be staggering.
Also these wind turbines are very unsightly and would ruin very beautiful and scenic parts of the country. It should also be noted that they only produce power 1/8 of the time that they are running. That is not very efficient, but we are on the right track, things just need improvement.
Another problem I see with wind turbines is the amount of profit many companies stand to make for putting them in. Individuals are making millions off of this and that is just not right when our well-being is at stake.
However, if you're interested in using wind power as your own source of alternative energy, it is a viable option. Many farms and rural communities use these wind turbines to power themselves. In smaller numbers, the cost of building the turbines pays for itself relatively quickly. But wind energy is only one form of alternative energy. Next, we will look at using solar power as an alternative power source.
Solar Power
Solar power is alternative energy derived from the power of the sun. Solar energy is also completely free, except for the cost of installing the equipment necessary to convert the sun's rays into usable electricity. This equipment is becoming less and less expensive every day. Solar power generally ends up paying for itself within the first few years.
The equipment needed to use solar power as an alternative energy source for your home can be bought at virtually any home improvement store, and can usually be installed in just a few hours. If you don't feel comfortable doing it yourself, there are a great number of contractors available who can install your solar panels and generators for you.
Regardless of which type of alternative energy you choose to use in your own home, the fact remains that we must find a renewable source of energy soon, or be at risk of losing the few natural resources we have left to burn. Contact your Congressman today, and ask what is being done to find a good source of alternative energy; and what you can do to help.

Wind Turbines–Build A Wind Turbine For Free Power

Fri, 23 Jul 2010 23:15:58 +0000

Wind turbines are the best answer to the high and rising cost of energy. Electricity created from wind power is the best answer to one of today's most serious problems--the high cost of fossil fuels.
There are other ideas which may help of course. Solar power is clean but,at the present time, solar panels are quite high priced and have limited power output. Their best use is probably as an addition to wind power production. They can be used as roof panels on a building and will supply additional power.
Nuclear power is another source and this form of power is being used in many places around the globe. The cost to build nuclear power plants is very high however and there is a lot of public opposition to their use after the Three Mile Island and Chernobyl disasters.
Nuclear power stations will probably be a large part of future power supply around the world. If well built with all necessary safeguards they have been shown to be dependable and safe.
Wind power is at present the best all around power source for small scale power generation. Small individually owned wind power turbines can supply a large portion of our power requirements in the years immediately ahead.
Many companies are now offering wind turbine generators for sale to the general public. They are being installed by town and country property owners in ever growing numbers.
An alternative is to build a wind turbine,from available plans,at a very big cost saving. Any home owner or farmer in city or country may use this type of low cost power and be completely independent of the local power utility.
It is not even necessary to have high winds all the time. Even gentle breezes will generate some power. This power can be stored in batteries for future use.
A very good wind turbine power generator can be built using new or used auto parts. It may be installed on a roof or on its own tower. The construction of a turbine from available plans and instructions is really quite simple. The average person who can use simple tools will have no trouble in building one or more of these wind generators.
Excess power which is produced can be sold to the local power utility in many places. This type of wind turbine or windmill was much used on farms in the 1930-1950s era and was proven to be reliable. Two or three of them can be built to supply all the power needed and this can be stored in batteries till needed for use. Build it and the wind will come-- and bring free power along with it for your use.

Uninterrupted Power From Wind Turbines !

Fri, 23 Jul 2010 04:53:15 +0000

Are there any back up techniques?

Wind Turbine systems are available in several designs according to the way they store surplus power generated. For example:

Grid Connected Off Grid Stand alone Hybrid System etc.

Incidentally the applications of each of the above types will depend on the;

Availability of the National Power Grid within an economically viable distance. Ability to sell back surplus power to the National Grid. Buy-back price of unit energy uploaded Whether a reasonable and consistent wind flow is available at the site through out. Availability of a stand-by battery bank of adequate capacity and maintenance of it.

Of these the Grid connected and Stand Alone systems possess the ability to provide continuous power supply to the end user. A hybrid system will possess the same capability subject to it works as a stand alone system.

Stand Alone Small Wind Turbines

Stand Alone systems are Wind Turbines not connected to the Grid Supply but uses a battery bank to store surplus energy generated when the optimum wind velocity is available. The Electrical Energy stored in the battery bank will supplement the power needs of the home as Direct Current (generally below 5 kw) or in the case of higher capacity generators (generally above 5 kw, as Alternating Current.

In the case of the low capacity DC generators the surplus power generated will be directly stored in the battery bank. If the appliances and the power distribution of the home is AC oriented an inverter will be used to convert the power to AC prior to feeding the home distribution.

If the Wind Turbine is generally over 5 kw the electrical energy generated will be alternating current and cannot be stored in the Battery Bank direct. The inverter in this instance will be converting AC to DC for this purpose after stepping down the voltage from 230V (415V if it is 3 phase) to 12 V DC (nominal) generally and stored in the Sealed Lead Acid Battery bank. The inverter will convert the stored energy to AC again when the home demand dictates so.

Hybrid Wind Turbine Systems

A hybrid system will be similar in general to the above stand alone system but will incorporate Solar Powered PV Panel arrays (or diesel Generator Sets) to supplement the wind generated power in situations where the wind velocities decrease due to climatic or geological reasons during the year. The PV panel arrays have purpose designed inverters. Controls for matching the two systems are too necessary. Therefore one must be careful as to what he has to order additionally. Professional assistance in all these cases is therefore strongly advised.

Storage Battery Banks

The battery bank will require quite a few safety devices (such as over charge cut-out, Over current and voltage regulators etc) and controls which are generally solid state. The battery bank is located in a well ventilated (preferably air conditioned) room which is isolated from living areas. (This is because they release corrosive fumes and also pose an explosion hazard to some extent).

Adequate space for regular maintenance is a must. The batteries are of the deep cycle type (regular charging and discharging up to 80% of it's capacity is possible). Automotive batteries (shallow Cycle type) are not suited for this application.

Grid Connected Small Wind Turbines

A grid connected Wind Turbine Power System does not need such a huge array of additional components. It requires only an inverter to make the generated electricity supply compatible with the grid supply along with the necessary power cabling and controls. When the wind generated power is not adequate all it has to do is to draw the additional demand from the power grid. A kwh meter is of course required whether you want to buy the short supply or sell the excess production to the utility.

The cost of power cabling and installation may be high if the distance it has to be drawn is far. As you see it is possible to obtain a consistent power supply from small wind turbines. Under proper guidance these could be made very cost effective too.

Wind turbines are not capable of providing uninterrupted steady power by themselves simply because the wind velocities incident on them fluctuate widely.

Small Wind Turbines are good for power generation as long as the wind velocities 4.5m/s upwards is available. What if wind velocities drop below 4.5 m/s or rise above 16 m/s?

How Do Wind Turbines Work? – Very Easy Process

Mon, 19 Jul 2010 18:50:21 +0000

With high electricity bills and concerns for the environment, many people look for alternative sources of energy. One of the most popular and easy to install is a wind generator. But how do wind turbines work? The process is quite simple, really, and looks a lot like the old grain windmills with, of course, a lot of technology advances added over the years. The basic process on how wind turbines work goes like this:

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!

Wind Turbine Types – How To Trap Wind Energy For Productive Use

Tue, 13 Jul 2010 13:07:59 +0000

Wind power is conversion of energy from the wind to be used productively in many ways. There are many machines, wind turbines, which transform the kinetic energy of the wind into mechanical energy by converting it. The mechanical energy then works with the kinetic energy so that it becomes balanced into a mechanical system. Once this mechanical energy is turned into electricity this system is then known as a wind turbine.
Horizontal Axis and Vertical Axis are the two different types of wind turbines that can be found. The Horizontal Axis Wind Turbine is the more popular of the two and features a main rotor shaft and a generator which are located at the top of the turbine. There is a gearbox attached to most of these turbines, so that more electricity can be generated by the quicker turning of the blades. The turbine are tall towers with blades which create turbulence for power, and turn either upwards or downwards. In high winds, upward blades can crack and breakdown as they are not able to withstand these conditions for too long. Downward blades are in line and face the wind so they last longer. They are even durable against the high winds so do not break which helps to keep down the cost.
The Different Types of Horizontal Axis Wind Turbines
Windmills - They usually consist of four or more blades that are normally short. There are some that are made up of wood and were first used to grind up grain. Winds rotate the mechanism of the blades which turned a mill that the grains ran through so that it was crushed.
Rural Windmills - These originated from Australia and were later built all over the U.S.A. Farmers found these windmills useful in pumping water into the fields and electricity for the barns. There are several blades on this type of windmill, which are still in use today and can be seen in the fields. So that electricity could be carried for lighting or even a radio, they were constructed using metal.
Modern Turbines - These are used today and what we see standing in our fields. The features are of three blades which become pointed towards the ends. The reasons for this unusual shape is after trials and testing, they proved to be the strongest for exceeding up to 6 times more wind velocity, which allowed for high efficiency and was more reliable.
This sort of wind turbine has many advantages including being bendable, durable, it has stability, is strong and also tall. On the other end, the disadvantages are that they are not as in huge demand, they are unable to operate if they are too close to the ground, installing them is a difficult job as well as transporting them by sea. There are also concerns that they can affect radar, and they can suffer from strutual damage during high storms and with wear and tear.
So as you can see, there are good and bad points to buying and installing these types of turbines. They do work so whether you choose to have one or several if you own a field is up to you. They are good to help generate electricity and many other things that we would might well have to do without.

How to Build a Wind Turbine

Mon, 12 Jul 2010 00:26:56 +0000

With society slowly moving towards a cleaner and greener planet, alternative energy is being pushed more and more into the spotlight. Wind power currently comes in second only to natural gas as a renewable source of energy. Last year there was over 1700 megawatts of power product by wind turbines. This year it wind power is expected to account for about 1.5% of the US power needs. Commercial wind farms will account for most of this energy however residential wind turbines are becoming more and more popular and are slowly helping to reduce harmful emissions which tend to pollute our atmosphere; this is why more people want to know how to build a wind turbine. Wind power is a very clean source of energy, especially when compared to fossil fuel energy which is the main stay in today's world. Usually the only objection to wind turbines is their so called "visual pollution" and sometimes even the noise that they create. This however is not the case with residential wind turbines. Today's wind turbines are very compact thanks to technology and they can contribute quite considerably to the overall household energy consumption which in turn saves you money. In fact if you combine it with a solar power unit you could quite easily power your average sized home. While there are household commercial units available, with the advent of the internet there are a number of guides that can easily show you how to build a wind turbine and often at a cost of less than $200. Some people think that if you are planning on installing a wind turbine at your home that you have to be in an open area so you can get a maximum amount of wind hitting your turbine, this however is not the case as even the smallest amount of breeze can be enough to generate so electricity which will be stored in the battery units. The amount of energy that you can produce is a combination of wind flow and design. Obviously the more wind that the wind turbine is exposed to, the more energy that it can generate and the more energy that can be stored in its batteries. However the traditional windmill design that most people are familiar with isn't the only design. Roof top mounted wind turbines are comparably small units which do not use the traditional tower as these turbines are designed to be used in relatively sheltered or built up areas where there is not a good wind flow. If you live out in the country, these units can be fantastic for you especially if you are prone to having power outages and don't like to use your gasoline generator. The great thing about learning how to build a wind turbine is that you can make more than one turbine for your home which of course means that you will generate more power for your home which in turn means that you will save more money by cutting your power costs.

Wind Turbines–build yourself a Free Power Supply

Fri, 09 Jul 2010 14:45:47 +0000

Wind turbines are the answer to today's high cost of energy. Totally independent from the price of oil,gas or coal,electricity created from wind power is the best answer to one of today's most pressing problems--the high cost of fossil fuels. There are other solutions which can help of course. Solar power is a good example but,at the present time, solar panels are still very expensive and have limited power output. Their best use is as an adjunct to wind power. They can be used in the form of roof panels on a building to supply additional power.
Nuclear power is another obvious answer and this form of power is being developed in various places around the world. The initial cost of nuclear power plants is very high however and there is much opposition to their use after the Three Mile Island and Chernobyl accidents. Properly built and supervised nuclear power stations will probably be a large part of future power supply around the world.
Wind power is presently the most promising power source for small scale power generation. Individually owned wind power generators can supply a substantial portion of our power requirements in the years immediately ahead. Wind turbine generators are now manufactured by a number of companies and are in use by rural and city dwellers on an increasing basis. Another alternative is to build your own wind turbine at a very substantial saving. It is possible for any farmer or home owner, whether located in city or country,to access this free form of electric power and so become completely independent of the power utility.It is not necessary to have continuous high winds. Power is generated by even the gentlest of breezes.
A very good wind turbine can be constructed using used or new auto parts. Installation can be on a building's roof or on it's own freestanding tower. It is actually quite simple to construct a wind turbine from available plans and instructions.The average person with a little home workshop experience can build one or several of these turbines quite easily. The power utility in many areas will now buy any excess power which you generate. This type of wind turbine has been proven to be extremely relisble and was used widely on farms in the period from 1930-1950s. Two or three of them can be built to supply as much power as needed and the power can be stored in batteries ready for use.

Home Wind Turbines – Cut Your Energy Bill

Thu, 08 Jul 2010 00:31:58 +0000

Energy costs keep sky rocketing with no end in sight. Pollution levels are increasing and our planet is facing a warming trend that could have devastating results. So the question is what can the average citizen do to save money and help the environment at the same time? One great way to help is to lower the amount of electricity your home purchases from the utility company by creating your own power. There are a few ways to do this, and wind power is one of the easiest and more reliable ways to produce energy at your home.

What is a Wind Turbine?

A wind turbine is a simple machine that collects kinetic energy produced by wind currents and converts this energy into power that can be used in the home. Wind turbines are installed on high towers; these towers are usually around eighty to one hundred and twenty feet high. Towers must be high enough to allow the turbine to be above any turbulence generated by objects on the ground. The higher the altitude also results in higher wind speed and in turn, a higher amount of energy can be produced.

How do Wind Turbines Work?

Wind energy is used to create mechanical energy. Turbines have blades that are turned by the wind; these blades turn a shaft to which they are connected. The shaft is then connected to a generator; the mechanical energy is transferred into the generator through the shaft and converts the mechanical energy into electricity. This electricity can then be used in the home for any electrical need. Homes that are using wind turbines to produce power are still hooked up to the power grid. Being hooked up to the power grid allows the home to still have power when wind currents aren't strong enough to produce electricity. Another benefit of continuing to be connected to the power grid is that at the times your wind turbine is producing more power than your home can use, the utility company is absorbing the extra energy and paying you for it. This can lead to very low electric bills. A wind turbine can lower your power bill by 50-80% depending on the amount of wind in your area.

Types of Wind Turbines

There are two main types of turbines: horizontal- axis turbines and vertical-axis turbines. Turbines also come in different sizes as well. Utility companies use wind turbines that can range in size from 100 kilowatts up to several megawatts. These larger turbines are found in groups on wind farms. If you ever drive over the Temecula pass in California, you can see large wind farms along the highway. It is a spectacular site. Small turbines, 100 kilowatts or less, are used at homes. These are place on towers on the homeowner's property and then used to provide some of the energy needed to run the home. Since the size of the tower is quite large, they are usually used in areas where the home is on one acre or more. There are very small turbines on very small towers that may be able to be of use in urban areas or on smaller lots.

The Future of the Wind Turbine

In September of 2008, the U.S. Senate passed a bill that grants a one-year extension of the renewable energy production tax credit. If passed by the U.S. House of Representatives the tax credit would be available until December 2009. Wind power is a viable part of the solution to lessen our dependency on fossil fuels. Wind power is a renewable resource and produces no harmful pollutants. The future looks bright for wind power and hopefully, as a result, there will be a bright future for our planet too.

Making A Home Wind Turbine

Fri, 02 Jul 2010 21:51:30 +0000

When one thinks of a home wind turbine, what most probably comes to mind is a gigantic tower with jumbo-jet sized spinning blades. But, with everyone becoming more aware of conserving energy, the technology has advanced so much that it is now possible to have your own small-scale wind turbine at home. Even better is the opportunity for us to make our own, without having to rely on the professionals.

So, how does a home wind turbine make power?

A home wind turbine makes power by spinning a generator. The generator is attached to the rotor, made up of three aerodynamic blades, that is then attached to a tower. To keep the turbine facing the wind, the rotor has a tail, that acts as a weather vain.

The generator is basically an electric motor. As the coils in the motor spin past the magnets, an electric current is produced. The power produced is stored in batteries, which are connected to an inverter to change the direct current to alternating current, which can then be used to power your home. The advancement of motor efficiency, is the reason wind turbines have become so popular for home use.

Depending on your area's wind conditions, the tower can vary in length. If you live near the sea where it is windy, the tower can be shorter, but in low-wind areas the tower needs to be taller to catch as much wind possible.

Over time the blades have improved drastically as researchers developed lighter, stronger, more efficient blades, with the capability of turning even in the lightest breeze. Back in the day, wind turbines had five blades, and looked similar to windmill water pumps, but recently they have moved to three blades, taking the form of over-sized airplane rotors. Like the tower, the blades vary in size, according to your wind conditions and energy requirements.

While so far we have been explaining the typical horizontal axis wind turbine, there is another design that is starting to gain popularity for small-scale projects. It is the vertical axis wind turbine or VAWT. Very different to the standard horizontal axis turbine, the VAWT spins on a vertical axis, and almost looks like a waterwheel put on its side. Since the VAWT tends to operate low to ground, it needs far more wind to make it turn efficiently, so it is not the ideal option for homeowners or small businesses. The VAWT has also been accused by ecologists of interrupting and harming various migratory birds, making it less attractive for green enthusiasts.

Before going out and installing a wind turbine, it is best to ask yourself the following questions:

- How big is the property?

Wind turbines generally operate better in large areas that cover an acre. This is because wind flow is not deflected by any nearby buildings.

- What is the average wind speed?

The recommended wind speed should be at least eleven miles per hour, but if that isn't the case then you may have to use a taller tower and larger blades to catch higher altitude winds.

- What else can I use the wind turbine for?

If you could use the turbine for other purposes, such as pumping in water from outside, then it may be useful than you think. This is the reason you see so many windmills scattered over farms - they help pump water from reservoirs to the farmhouse.

- Does my house need a constant power supply?

This is why so many people want to get a small wind turbine in the first place - to keep the house powered during blackouts, and prevent economic losses. Although the wind turbine may not power the house all the time, it's stored power can be used in emergencies, when the utilities are just not enough.

Answering these questions will give you a good idea of how much power you need, how big the tower a blades need to be, and how much it would be worth investing to start making your own power at home.

The great thing about technology is that it is always improving. So much so that motors have become smaller, efficient and cheap enough for us to attach a few small turbines right on the roof, and produce the same power as a larger turbine on a tall tower.

Although professional home wind turbines can run into several thousands of dollars, it is possible to make your own for a tenth of the price, with components found at home and your local hardware store. Furthermore, the U.S. offers both state and federal tax credits that you can use to offset the installation cost. So not only will you reduce your electricity bill, but also your tax at the same time.

Wind Turbines–build Your Own Home Wind Turbine

Wed, 30 Jun 2010 10:37:10 +0000

In the United States wind energy is the second biggest source of new energy outpaced only by natural gas. At the end of 2007 wind turbines were producing over 16000 megawatts of electric power and nearly one third of that capacity was installed in 2007. In 2008 about 1% of the united States electric power will be supplied by wind energy. Most of this of course is from large commercial wind turbines but an ever increasing amount is coming from small wind turbines installed by individuals. The home wind turbine is definitely coming into its own as more and more people realise that something must be done to decrease our dependence on electric power supplied by fossil fuel burning generating stations. Gas and coal powered electric power production has increased dramatically over the years and emissions from the fuels burnt in these facilities is a major source of atmospheric pollution.
Wind power by comparision is absolutely clean and the only objectiion to it,voiced by some people,is visual pollution from the arrays of wind turbines necessary for large scale power production. However the residential wind turbine poses no such problems. Relatively small and unobtrusive home wind turbines including vertical axis wind turbines are the key to small scale wind power generation. A combination of home solar panels-wind turbines can produce much of the power required by the average home. Small wind powered turbines are manufactured by a number of companies and can be readily set up either as a rooftop wind turbine or mounted on its own small tower. The recommended tower height is about 30 feet. These are relatively expensive but will pay for themselves in the course of time.
If you know how to build a wind turbine your home wind turbine will cost much less and fortunately this is fairly easy to do. Plans and instructions showing how to build your own wind turbine are readily available and thousands of people have built their own home made wind turbine. You will often be told that strong winds are needed for wind power generation. This is absolutely not so. Even gentle breezes will produce power which is stored in batteries till needed.
If you live far from electric power lines you either get by with no electric power or generate your own. Gasoline powered generators will do the job but they are expensive to run and heavy polluters. You may be fortunate enough to have a stream which can generate power for you using a water power system but these are usually difficult to build and expensive. In most situations a wind turbine is the best answer. You can in fact build your own wind turbine for much less than the price of a commercial model. You could install two or three of them and have plenty of power for all purposes. Building your own home wind turbine is a fairly simple project which the average home workshopper can easily manage. Wind power is the coming thing and will save you money as well as reducing atmospheric pollution. Why not try it?Like to know how to build your own low cost wind turbine easily?

Guide on Residential Wind Turbine

Tue, 29 Jun 2010 14:08:32 +0000

Residential wind turbines are a wonderful model to produce a cheaper source of free energy. Knowing what to search for and where to buy one is essential in getting you started. If you are looking for a suitable residential wind turbine kit, the good news is that there is lots of places where you can do so. This is not something you can just get at a ironware store. Instead, a little searching have to be done first. In fact, the internet is one of the best places to find and buy residential wind turbines kits.

Assuming you have decided to purchase it online, there are a few points to check if it is a good bargain. You want to be positive you only purchase them online from a site that extends free transport though. Do not purchase them offline if the company does not provide free shipping. If not, the kit will be extremely costly with accumulated charges tallied on. On The Average, a rational price for a residential wind turbine should be around $300. If you find any sales where the cost deviates quite a bit you may want be be skeptical. It may be a scam.

A wind turbine is more commonly referred to as a windmill. It can also be referred to as a wind generator. Though the terms are used interchangeably, each is not the same as the other. What makes a wind turbine different from a windmill? For instance, a wind turbine converts wind energy into mechanical energy that can be further converted to electrical energy whereas a windmill will just use the mechanical energy as is. As a windmill does not convert the energy, it cannot really be considered a wind turbine even though the words are often used interchangeably.

Let's examine the different types of wind turbines. Wind turbines are classified based on their orientation. There are two basic kinds of wind turbines known as the Horizontal Axis Turbine and Vertical Axis Turbines. The Horizontal Axis turbine contains blades that rotate across a horizontal axis. Conversely, The Vertical Axis turbine rotates its blade on a vertical axis. The Horizontal Axis Wind Turbines are more popularly used in various parts of the world. This is because horizontal axis wind turbines are more efficient than the vertical ones.

The advantages of installing a residential wind turbine includes saving power, cost effective, environmental friendly and perpetual power supply.

Some advantages of wind turbines include:

Perpetual power supply - You do not have to be dependant solely on the government for your power supply. Endless supply of power means never having to deal with a power outage too! Saving Power- Wind turbines use wind energy to produce the same energy that we have to pay electric companies to use so we save power by not having to use regular electricity. Cost Effective - Because wind is free, the only actual costs a user incurs is in installing and maintaining the wind turbine. Environment Friendly - Wind turbines run on a natural energy source and are therefore not harmful to the environment.

The benefits of a wind turbine so attractive that everyone would want to install one, but if it is not correctly done, it can be quite bad. Before installing a wind turbine, do consider the following.

You must have at least an acre set aside to install it on. Make sure the average wind speed is about 11 miles per hour. Make sure the tower and base are ironclad. It is the wind turbulence that can mess up your wind turbine so take that into consideration as well. Make sure that the distance between the wind turbine's height and the wind generator and cells is optimal.
