Design-The design of these small units is such as to allow for the least amount of wind to power them. Usually operating wind speeds of 10 miles per hour will start the production of electricity. Made with either 5 blade or 3 blade design, they turn a motor type generator that will produce a DC voltage to charge a bank of batteries. To prevent over-speeding they are equipped with a brake, so that at higher wind speeds they stop working.

Location-Newer types of small wind turbines are made to mount on the tops of houses unobstructed from trees or other buildings. Some companies are placing these smaller units in groups of two or three, mounted together forming a small wind farm. Other types are mounted on mast or poles above any wind blocking structures.

Cost of small wind generators-The cost of these compact wind turbines can be as little as $400 and much more depending on the output and size of the unit. There are other items that you must consider if building a small power system. Additional cost would be batteries, charge controller, inverter, and any wiring associated with the installation. Also the mast or mounting assembly can be expensive.

How does a small wind turbine work-The basic concept of operation starts with the wind turbine that produces electricity in the form of DC voltage. From the wind turbine you would go to what is known as a charge controller. A charge controller is an electronic device that regulates the flow of electricity to your batteries, not allowing over or under charging which will help prolong the life of your batteries. From the already mentioned batteries, an inverter is added that changes the battery voltage to usable house current to power your appliances or other electrical items.

Requirements-If you are thinking about installing your own residential wind turbine then you must check with your local code enforcement authorities to see if they are permitted. There may be height restrictions and other things to consider. It is always best to check first. If you are in the country then you probably have free-reign to do what you want. If you are not 100% sure about electrical installation, it is best to hire a qualified electrician to hookup your unit. Remember, safety first.

There are many things to consider about compact wind turbines. With recent increases in energy cost, people everywhere are looking for cheaper alternatives. Visit my website for more ideas and guides to help you build your own wind and solar systems.

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.

Wind Turbine Generators.

Small wind turbines work in a fairly straightforward way – large blades capture the wind and are forced round, thereby driving the turbine and generating electricity. Naturally the faster the wind speeds, the more electricity can be generated. However the majority of sites that would benefit most from a small domestic wind turbine are not located in windy coastal areas or on the side of mountains. Therefore it is vital to choose a turbine that has been designed to suit the moderate wind conditions found in rural, mainland Britain. With the right choice farms, large residences, offices, small businesses and public buildings, can effectively reduce energy costs and also decrease the UK’s carbon footprint. Two key factors that must be considered are wind speed and site suitability.

Suitable sites

In the UK wind speed can vary and is dependant on a number of variables. The clearest way to estimate the wind speed at your site is to find the annual mean wind speed (AMWA). This is an indication of how much wind is available, and in the UK that figure could be as low as 4 m/s to around 9 m/s. Areas with wind speeds of 4.5m/s, such as villages, small towns, woods and agricultural areas with many high hedges would expect to produce 19,000 kWh per year. Agricultural areas with some windbreaks and buildings would expect to see wind speeds of around 5.5 m/s, generating 30,000kWh per year. Finally, open landscapes with few buildings and no windbreak would expect to see wind speeds of around 6.5 m/s, producing 40,000kWh per year.

Generating money

Installing a domestic wind turbine has also become a far more lucrative proposition thanks to the governments new Feed-In Tariff, launching in April 2010. An average sized house will use 4,000 kWh in electricity annually (non heating), while an 11kW wind turbine will produce in the range of 19,000 kWh to 40,000 kWh depending on the wind speed at your site. If your site has an average wind speed of 5.5 m/s or higher, typical of most agricultural areas in the UK (check your average wind speed online), then it is likely that you will have excess electricity that can be sold. The Government have recently released the Feed-In Tariff levels, revealing exactly how much a wind turbine customer can gain from the incentive scheme. For wind turbines between 1.5kW and 15kW the Government will pay 26.7p/kWh of all electricity generated, whether used domestically or fed back into the grid. Therefore small domestic wind turbines customers can benefit in three ways: substantial feed-In Tariff payments for producing green electricity; lower electricity bills; and the potential of selling any excess electricity generated back to the grid.

Wind Turbine Generators.

Wind turbines can be arbitrarily divided into three classes: small, medium, and large. Small wind turbines are capable of generating between 50 watts and 60 kilowatts of power, and use rotors ranging in diameter from less than 1 to 15 m (3 to 50 ft). Small wind turbines are installed primarily in remote areas where power is needed but access to conventional sources of electricity is either too expensive or too unreliable. Some small turbines, known as micro-turbines, are so compact they can be carried to remote locations on horseback.

Most commercial wind machines are medium-size turbines. Medium-size turbines use rotors spanning diameters between 15 and 60 m (50 and 200 ft), and have a generating capacity ranging from 50-1,500 kilowatts. Most medium-size commercial turbines have a generating capacity in the range of 500 kilowatts to 750 kilowatts.

Large wind turbines are behemoths with rotors spanning diameters between 60 and 100 m (200 to 330 ft), and are capable of generating 2 to 3 megawatts of power. Because the cost-effectiveness of conventional coal-fired and oil-fired power plants increases with the size of the plants, it was originally thought that giant wind turbines would be more economical than smaller turbines. Various countries have attempted to develop commercial multi-megawatt wind turbines, but these machines have proved less economical and less reliable than medium-size turbines.

GROWIAN Wind Turbine, Germany

Looking for an alternate energy source during the oil shortages of the 1970s, German engineers constructed the experimental GROWIAN turbine to generate the maximum amount of electric power with the biggest turbine possible. With blades nearly 50 m (160 ft) long, it was the world's largest wind turbine at the time of its construction. The massive turbine proved difficult to maintain and is no longer in use. Through this experience, engineers learned that medium-sized turbines could harness wind energy at a more cost-effective rate than large turbines.

These are freely available online and can provide an excellent concept about how much power you might generate from the wind.
When you have an idea about the average wind speed, think about the size of turbine which will fit your property. If you have masses of open space, you'll be able to buy a larger turbine to take better advantage of the available wind. The most commonly available little wind turbines are rated at 250W, 500W and 1000W, but this doesn't mean that they'll always generate this amount of power. The rating is generally for a comparatively high wind speed, as high as 30 mph. Most areas of north America do not have wind resources this powerful.

This indicates that a 1000W rated turbine may only constantly generate 400-500W of power. Obviously if you would like to generate an important quantity of power from the wind, you are going to need more than one turbine. Quite often there's a negative link between power demand and wind speed. Many hot, wet summer days come with tiny wind.
Working with these issues is the prime concern when coming up with your home replenish-able energy system using small air turbines. Though the out of doors section of the system is the most obvious, the genuine wizardry occurs within. Elements like charge controllers, batteries and inverters give the chance for you to use the energy generated by your small wind turbine at some specific point in the future. This indicates that your turbine can be generating power in the middle of the night that you could use the following day. This is the perfect situation for using replenish-able energy at home.
Commercially available small wind turbines are not the only real way to satisfy the necessities of your green energy system. If you want to tackle DIY projects, a wind turbine is not very difficult to build. When you create your own tiny wind turbine, you can figure out how much power it will generate and you can tailor it to your system. This advantage alone makes this project worthwhile for those that may handle it. If nothing available commercially suits your wishes, think about this option.

However, if you still think your location would be suitable for using small wind turbines, do a quick search to find wind maps of your area.  These are freely available on the internet and can provide a very good idea about how much power you could generate from the wind.  There may be other reasons that you are not seeing wind turbines used in your area beyond having suitable wind resources.

Once you have an idea about the average wind speed, think about the size of turbine that will fit your property.  If you have lots of open space, you’ll be able to purchase a larger turbine to take better advantage of the available wind.  The most commonly available small wind turbines are rated at 250W, 500W and 1000W, but this doesn’t mean that they will always generate this amount of power.  The rating is generally for a relatively high wind speed, as high as 30 miles per hour.  Most areas of North America do not have wind resources this strong.

This means that a 1000W rated turbine may only regularly generate 400-500W of power.  Obviously if you want to generate a significant amount of power from the wind, you’re going to need more than one turbine.  Quite often there is a negative correlation between power demand and wind speed.  Many hot, humid summer days come with little wind.  This means that in the middle of the day, when power is required the most, wind sources can’t provide it.  Knowing how to take advantage of this will make your small wind turbine project successful.

Dealing with these issues is the prime concern when designing your home renewable energy system using small wind turbines.  Although the outdoor section of the system is the most visible, the real magic happens inside.  Components such as charge controllers, batteries and inverters make it possible for you to use the energy generated by your small wind turbine at some point in the future.  This means that your turbine can be generating power in the middle of the night that you could use the next day.  This is the ideal situation for using renewable energy at home.

Wind Turbine Generators.

The UK government already generates significant energy from offshore and onshore wind farms, but generally businesses, farms and country estates are not situated in typical high wind speed areas. For sites in moderate wind speeds, most villages and small towns, a small domestic wind turbine could significantly lower energy bills while owners could benefit additionally from the government's Feed-In Tariff scheme.

Small, domestic wind turbines operate in a similar way to the giant wind turbines in large wind farms. Large rotor blades rotate around a central hub, which is connected to a gear box that drives a generator. These are located inside what is known as the nacelle, which can be seen behind the rotating blades. All electrical components are housed inside the nacelle which sits on top of either a cylindrical tower or a lattice tower, depending on the manufacturer. This type of turbine is known as ‘horizontal axis'.

Tower height can range from 10m to 30m, with 18m being the most popular for small businesses, farms and country estates. Tower height is important to performance: there is a 10% difference in energy production between a 15m tower and an 18m tower. It is always recommended that anyone considering a wind turbine contacts the local authority before installation as some councils impose height limits depending on site location.

Site location is another factor that is crucial to the performance of a small wind turbine. It is important to consider the surrounding area and how the landscape could affect wind flow. A domestic wind turbine will operate best when there are very few obstacles in the surrounding area. An exposed location without many buildings, trees or hills is the perfect area for a wind turbine. It is possible to successfully install a wind turbine with good results in areas that contain wind flow obstructions, however results will not be quite as impressive.

Wind technology is improving all the time and with a growing number of suppliers in the market the costs of installing a small wind turbine have fallen dramatically. The UK government has set a number of energy targets to achieve over the next decade, and expects a large increase in domestic renewable energy installations throughout the country.

The introduction of the UK's Feed-In Tariff allows owners of wind turbines to benefit from a payment for all clean energy generated. For example if a small domestic wind turbine with a rating of 11kW was installed on a site then the owner would benefit from 26.7p per kWh generated. On average an 11kW turbine would be likely to generate between 15,000 and 40,000 kWh per year, depending on wind speed (for example the difference between an average wind speed of 4.5 m/s and 6.5 m/s). In order to be eligible for the tariff the manufacturer and product must be listed on the Microgeneration Certification Scheme's list of accredited suppliers.

It is important to understand how small wind turbines work and consider their suitability on a site by site basis. However there are a number of benefits to owning a small wind turbine, and after the initial investment there is the potential to earn significantly in a number of different ways.

Wind Turbine Generators.

The first thing that many people ask about home wind turbines is how they work. In essence, a turbine, which is placed on top of a tower, collects energy from the wind and turns it to usable electricity. In residences that are not located in remote areas, it is still necessary to get the services of your local utility company because the energy generated by the turbines will not be enough. It is also worth noting that the speed of the wind can greatly affect the electric output of your home wind system. If the wind speed is lower than 7 miles per hour, you should not expect any output from your turbine. However, if you are able to generate more electricity than what you need, your local energy company can purchase the excess power from you.

Another concern for homeowners is how much money is saved when they use home wind turbines. According to studies, a small wind system can actually cut your bill by as much as 50 to 90 percent. Some people even claim that after successfully installing a wind system in their homes, they only pay $8 to $15 dollars in monthly electricity bill for more than two-thirds of any given year.

However, you should understand that the size of your home wind turbine will greatly affect the amount of money you will save. The higher the output of the small wind turbine, the more significant the impact will be on your electric bill. It would be a good idea to use several small wind turbines in order to generate enough usable electricity. The most common turbines available in the market have 600, 800, 1,000 or 3,000 output watts.

Before you buy home wind turbines, there are some things that you need to consider. First, you have to determine local laws on installing small wind systems in your city or locality. You do not want to end up buying a wind turbine only to realize later on that you cannot use it at home. Furthermore, you also need to choose a home wind turbine that is suitable to the size of your home and the size of your property. Furthermore, you also need to look for an online store that will not only provide you with quality small wind turbines but will give you value for your money as well.

Here we discuss the installation and the working of wind turbine:

Wind turbine are generally installed in remote areas where is a plenty and consistent flow of wind, but incase of homes small wind turbines are installed to generate electricity. Here are the necessary steps for installing wind turbine:

Examine the supply and flow of wind, at increasing heights the supply is good..
Decide the wind turbine you wish to install depending upon the amount of usage. Wind turbine cost $40,000 produces 10 kilowatts of energy.
Obtain the permission for installing them, because wind turbines are tall structures that require a building permit. Permit also includes notification from the neighbors and society.
Connect the wind turbine to the grid, this is the last step in installing wind turbine. The grid is connected with special electric meter. This meter is designed to spin in both the ways, it increases as you use power from the grid and decreases as you supply power to the grid.

Working of Wind Turbine:

Wind turbine is a old technology applied to fulfill new challenges. We need to fully apply this technology to protect global warming and the build up of carbon dioxide. The electricity generated by the wind turbine is transmitted through distribution lines to homes, schools, and business and so on.

Wind turbine works the opposite of a fan. It uses wind to generate electricity instead of using electricity to generate wind. The wind turns the blades which is connects to the shaft. In turn the shaft is connected to the generator and produces electricity. For home, telecommunications dishes or water pumping single small wind turbines are used which is below 50 kilowatts.

There are two types of wind turbine – horizontal and vertical wind turbine. Horizontal wind turbine is more common to use as compared to vertical wind turbine. They are also classified on the basis of off shore and on shore and even on aerial wind turbines. Each of them are having their advantages and disadvantages.

Wind turbines and their operation
A wind turbine is a machine that can convert the kinetic energy of the wind into electrical energy. Blowing wind rotates the blades of the turbine and the mechanism in it can generate electricity upon this rotation. Wind turbines have mainly two types. Horizontal axis and vertical axis wind turbines. They both have advantages and disadvantages but horizontal axis ones are more common due to higher efficiency.

Individual wind turbines
Individual turbines can be used for various purposes ranging from supplying energy for some small electrical devices where grid connection is not possible to meeting part of the energy demand of a house, a farm or even a production facility. Individual generation systems can be standalone or grid connected. The energy output from a standalone wind turbine can be directly used. However, in grid connected systems excess electricity produced can be supplied to the national grid system. In Ireland, you will have chance to be paid for the excess electricity you supply to the grid up to 500kW. Individual wind turbines can range from as small as 50W to as large as 3 MW, depending on their purpose of use.

Individual wind turbines for domestic use
Unlike large industrial wind turbines, these turbines have smaller dimensions that make them appropriate for using in relatively smaller areas. Their capacities range from as small as 50 watts to as high as 50 kilowatts and their prices vary depending on their sizes, types and manufacturers.

What to do for installing a small wind generation system?

First of all you have to decide whether you really need a small scale wind turbine for your energy needs. Sometimes just saving some energy can lower your bills but if the reason for considering a small turbine is being in off-grid areas you can proceed to the other steps. Inspect your site or your building (for rooftop turbines) to see whether it is appropriate for installing a wind turbine. You should have enough space to install a turbine without the wind being blocked by other buildings or obstacles. Determine your energy needs. Your utility bills will probably be your best references. See if the place you will install your turbine is windy enough. You can always find wind measurement data in wind energy associations’ websites for your area. Depending on your energy requirement and the wind potential in your area, decide the capacity and type of the turbine you will need. Your small scale wind system is expected to have a ROI period of maximum fifteen years. Economic lifetime of a small wind turbine without changing the main elements is estimated to be about twenty years and proper maintenance will increase this. However, maintenance needs of small wind turbines are expected to be minimal. Get any permits required in your area. You will probably need a contractor for erection, assembly, electrical connections of your wind turbine. However, if your turbine is micro scale, you can do these jobs by yourself as well. You can find domestic scale wind turbines and also 400W or 1 kW self installed turbines and accessories on windturbines.ie.

Individual wind turbines for industrial uses, i.e. factory sites
Turbines for industrial uses have capacities between 500kW to 3 MW. You will be able to generate electricity for wind speeds between 3 m/s and 25 m/s. For times that the wind is not blowing, one can still get electricity from the grid. This will result in additional revenue in addition to your reduced electricity bills.

Steps towards a wind turbine installation in your factory site:
The steps that should be made for installing an industrial scale wind turbine are approximately the same as those for installing a domestic turbine. The only difference is that they require more expertise. So it would be a good idea to take a turnkey service from an expert company in order not to experience any problems. The stages for a turbine installation are outlined below:

Wind Measurement: As your annual electricity generation depends mainly on wind speed, this step is of vital importance to be able to forecast your energy production. You can never know what you will generate without knowing what you have in hand. Feasibility studies: This will be a detailed study to let you know whether your proposed system will be a feasible project or not. Grid connection studies: This step assesses grid connection possibilities for your proposed wind turbine. Permission: Planning and installation of your wind turbine will require some permits on planning stage and during installation. Failure to get these permits may result in legal enforcement. Project budget planning: What you will need to spend for your wind turbine project from beginning to the end is an important item in any kind of planning for business. Procurement, commissioning and installation: All your equipment and staff needs for a turnkey project. Post-sales services: Issues like warranty, technical service, and maintenance.

What is a wind turbine? How does it work?

A wind turbine is a machine that converts the energy in the wind to electrical energy by means of rotating blades and a generator. Of course the working principles of a wind turbine are much more complicated. They include transmission elements, safety units, controllers etc. The blades rotate by the blowing wind and the rotation is transferred to the generator within the turbine. And this generator is the source of electricity. Then from the generator depending on the configuration of the turbine electricity is fed to the grid or directly to the point of use.
What is the difference between a commercial and a residential wind turbine?
Just their capacities! While a commercial wind turbine can have a capacity of up to 5MW residential wind turbines are generally much smaller, i.e. a few hundred kilowatts maximum.
Why do people consider purchasing them? Isn't buying electricity from the grid cheaper?

Actually, at the beginning yes. When the investment costs of a wind turbine is considered and reflected over years, for the first couple of years buying the electricity from the grid can be cheaper. However, the aim of using residential wind turbines is not only cheaper electricity. First of all they can be used at places where there is no grid connection. For example, farm houses far from grid connection or special small electrical appliances located in places where no grid exists can make use of small wind turbines for their electricity needs. In addition to these, wind turbines generate "clean energy". This means that for generating electricity by wind turbines you don't cause carbon dioxide emission like in many generation processes. Furthermore, in Ireland use of wind turbines for residential needs is also supported by the government and there are grants available for the initial investment. As a final remark, having a wind turbine for part of electricity needs of your house will result in a better Building Energy Rating (BER) report which will eventually increase the market value of your house.
Can wind turbines be used for any house?

No. First of all you have to make sure that there are not much obstacles (other houses, high towers etc.) that block the wind of the turbine. Second, you need to learn how windy your area is. For commercial installations generally measurements are made 6 months-1 year in advance of installation at the exact turbine location but for a small scale turbine you can use the wind statistics published generally by the government offices. Be sure to choose the measurement location closest to your area. For relatively less needs, such as a single appliance, roof-top wind turbines can be also used. Prior to installing a turbine always take the necessary permits that are required in your area.
What if a turbine generates more electricity than required?

Residential wind turbines can be either standalone systems or grid connected systems. If you have enough space to build a larger wind turbine then you can have it grid connected and you can get paid for the electricity you supply to the national grid.
How much can someone save with a residential wind turbine?

Actually, this all depends on your consumption and the capacity of your wind turbine as well as the wind conditions in your site. To give a rough estimation; some studies show that you can decrease your electricity bills up to 80 percent with a residential wind turbine of appropriate size.
What about maintenance of turbines?

Many small wind turbines have a small number of moving parts which make them suitable to use without maintenance for a long time. A wind turbine is expected to have an economic life of 20 years.
Where can I get detailed consultancy about residential wind turbines?

Windturbines is the largest retailer of micro turbines in Ireland, selling and installing over 100 turbines nationwide in 2008.

The Act offers a federal tax credit for 30% of the total installed cost of any wind power system with a 100 kilowatt capacity or less, but the credit will not exceed $4,000. The limitation of the Act is that it only applies to new systems installed from 3 October 2008 through to December 2016, so any current systems will get no tax relief.  In addition, for home wind turbines, the credit is further limited to the lesser of $4,000 or $1,000 per kW of capacity.

America, who has typically lead the worldwide small wind turbine market recently begun to feel pressure from other nations that offered enticing incentives for small renewable energy systems. So the new legislation was warmly welcomed by a Small Wind Advocate of the American Wind Energy Association (AWEA), Ron Stimmel, who said:

"We thank Congress for recognizing and supporting small wind systems as an important contributor toward energy security and a cleaner environment. This credit will help individuals cut their electric bills while combating global warming in a tangible way."

This bill is the first federal incentive for small wind turbines since 1985, and industry members believe the credit could grow the U.S. wind power market by 40% or more annually. And along with the upcoming equipment certification scheme, it will help secure it as the global leading market.

To put the industry on equal grounds with the photovoltaic (PV) solar industry, the AWEA, and its members have long requested a 30% federal investment incentive for small wind turbines 100kW and smaller. And now their persistence has paid off.

Since the two industries share the same renewable energy market, the wide legislation also expands on a similar credit for the PV solar industry that was first enacted in 2005. Domestic PV solar systems now receive a 30% credit, limited to $4,000, and commercial installations can get the same, but uncapped, credit.

So how does this act affect anyone who has installed their own system?  By the looks of things, diy renewable energy enthusiasts can also enjoy the federal tax credit as long they have proof of all installation costs and the date they were incurred. But, it is best to get sound legal advice first to help you maximize any tax credit due.

With the new tax credit, coupled with potential state-side credits, we cannot see a better time for anyone to invest in their own renewable energy system at home and offset the wind turbine cost. Whether this means getting an expensive professionally installed solar/wind power hybrid, or learning to do it yourself, potential electricity savings are a decision away. At the end of the day the choice is yours.

Most people can utilize these small home turbines but the are a few ideal situations, such as someone living on a farm, who can employ multiple turbines for increased output and efficiency.  The ideal average windspeed for a residence should be at least 11mph. If it's any lower, you may still be able to install a turbine but you may need to take special measures.

A home wind turbine can also be excellent for someone who would like an uninteruppted power supply.  Random power outages can wreak havoc on certain home electronics such as computers, which can cause costly repairs and loss of saved information. Even if your normal power supply goes out, a wind powered system will provide electricity at all times. Not to mention saving you from resetting all the clocks in your house after loss of electricity.

A normal turbine is made up of a tower and 5 blades which turn to create the energy.  The height of the tower depends on the location of your home. The less wind in your area, the taller the tower will be.  If you live near somewhere like a beach, the tower doesn't need to be very tall at all. As the wind blows, the blades spin, this energy is then turned into electricity which can be used to power appliances or anything else that uses electricity in your home. The electricity can even be stored up, so when wind dies down or your regular electricity cuts out, you won't lose power.

I'm currently an environmental science student and after studying the state of the world's resources, I'm doing my best to get people excited about alternate energy.

When we look at the sources we use today one can say that they not only give us energy, but we pay a high price for it. Not only is the actual market price for traditional energy increasing the problems are getting bigger too. One disadvantage of using fossil fuel is that the supply is limited and with a growing demand the prices increase. Prices for petrol are increasing on a daily basis and ordinary people are really feeling the financial pain. It doesn't look that this price increase will be turned around soon, instead we'd better get used to these high prices.
The pollution it causes has it effect on the climate by increasing the earths temperature. The effect on the earth climate is dramatic and we witness the consequences every day. Hurricanes, heavy rains and heat waves are some of the negative effects on our climate. Of course not all these are the blame of pollution, but it can not be ignored. By using these fossil fuels we are slowly poisoning the world we live in, killing the very civilization we hope to strengthen.

In search of the alternatives for traditional energy the concept of self-sufficient alternative energy was born. But what is it? It is the concept that your house can produce its own energy from the sun, wind and water. You can use sunshine to convert the sun rays into electricity and hot water. You can use the hot water to heat your home and of course for running hot water. With small wind turbines you can create your own electricity as with flowing water. These energy sources are available for nearly every one and best of all it is free. They also don't pollute the environment and that is a great advantage.

For the self-sufficient alternative home you will need the technology to convert these energy sources into usable energy. This all seems great but the technology comes with a price-tag and it can be substantial. Depending on your location you might be able to use the mentioned energy sources. The more you alternate energy you can convert the more you save. When you look at the savings you should not overlook the investment. On the other hand you often can take advantage of tax credits, but that depends on where you live. Of course you can use the internet as a source of information on the latest news on tax credits; it will save you a lot of money and will shorten the return on investment.

There are enough reasons to make you home a self sufficient energy home. There are various ways to achieve this. If you are planning to invest in alternate energy take the time to do the research and let a reliable company walk you through all the alternatives including tax credits and other benefits. This will be an investment you will put a smile on your face for saving money and making this earth a better place. Others may see you as their inspiration and follow your footsteps.

Rooftop wind turbines offer a relatively inexpensive way to participate in the rush to renewable energy. The principle allure is low installation cost. Typically, tower installations for larger turbines add 50-80% to the cost of the system. With a rooftop turbine, an $800 tower is replaced by a $39 roof mounted tripod, or a length of pipe attached to the side of the house.

According to Ron Stimmel of the American Wind Energy Association, "…rooftop turbines still account for only 1 percent or so of the 10,000 small wind turbines that are sold each year in the country." For this reason, few performance statistics are available from actual owners.

It's possible, however, to get an idea of the estimated power output of a rooftop turbine from the manufacturer's website. For example, the Energy Performance chart for Southwest Wind power's 200W Air Breeze predicts 20-30 kWh (kilowatt hours) per month from 10-12 mph winds occurring 6 hours per day.

To put this in perspective, 30 kWh is less than 5% of the power consumed each month by the average household. Overall, the payback from a single, roof mounted turbine in tangible financial terms leaves a lot to be desired; especially in light of the fact that unlike solar, there is no Federal tax credit for residential wind power.

But anyone thinking about installing a rooftop turbine(s) is probably aware of this already. The rooftop wind enthusiast is not motivated by financial relief, but rather the intangible rewards of pride of ownership, walking the walk, or simple satisfaction as a hobbyist.

Motivation aside, it doesn't make sense on any level to proceed with a wind powered project unless the three following requirements are met:

1. Higher than average cost per kWh. The more you pay per kWh for electricity, the more economical wind power becomes. A rule of thumb in the wind turbine industry states a residential wind powered system shouldn't be considered unless you pay $0.10 or more per kWh for electricity.

The easiest way to determine your cost per kWh is divide the current monthly balance on your electric bill by kWh usage (also plainly stated on your bill).

2. Building codes. Visit your building department to find out if there are any zoning restrictions for roof top turbines. Don't build your rooftop system first and ask questions later - only to be told it violates zoning laws and must come down.

3. Minimum wind speed. Wind speed of 7 mph, or 3 m/s (meters per second) is the start up speed for just about every wind turbine. However, in order to get any "juice" out of the turbine, minimum wind speeds of 10-12 mph for 6 hours per day are necessary.

Although wind speed charts for the United States and Canada are available to help site larger turbines, they're of little use for rooftop systems because the data is collected at a minimum altitude of 30 meters (98.4 feet).

However, you can get a good idea of the wind speed at proposed turbine locations by purchasing an anemometer (wind speed meter) for around $150. The kit comes with a rooftop sensor, 60' of cable and mounting hardware for the read out display. These are not data logging meters, so you'll have to keep notes on your observations.

If you're really serious about wind speed data collection, you can purchase a data logging anemometer kit with tracking software for $400.

Depending on where you live, wind speeds generally fluctuate with the seasons. Readings taken during the hot summer months of July and August, when you're begging for a breeze, are not usually a reliable indicator of average yearly wind speed.

Also, rooftop turbines located at the edge of a long flat roof experience much more wind than those located on roof peaks.

If, after a month or two of collecting data you determine there just isn't enough wind for a rooftop wind turbine, you can always resell the anemometer and turn your attention towards solar.
