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.

Most people may also be asking if the small wind turbine will be able to even power up their homes lamps. After you have answered prior question this is a even bigger one, is it worth creating a small wind turbine.

Which is certainly worth it even if you decrease your power by 5% you will be getting more money into your wallet. And besides lowering your electricity you will be taking action into making this planet cleaner and healthier.

The power, that's what you really want to know about, how much? This little wind turbine will make anywhere from 10 to 50 kilowatts of pure power for your home and appliances. The reason why you will not be making over one hundred or even one thousand kilowatts of power is because the wind turbine has a smaller body, blades and the tower isn't as high. Now how high is the tower to be considered small? Great question, this small windmill will have a tower that is between 30 to eighty feet in height.

The noise that the small wind turbine makes is not all that much from the larger ones. The will have nose or they aren't working. The noise is from the blades turning when the wind is blowing strong enough to make them turn. The noise level from the turning blades is not high at all. But if you don't even want to have a little noise you can fix that issue, all you have to do is choose a better place where the windmill isn't close to your house.

Exactly why might anyone want to build a small wind turbine to start energizing their houses? That is a very good question. The key reason why folks want to build a small wind turbine is because it'll be making very clean power. Creating a little windmill is excellent for everybody who is starting. So starting off building a small wind turbine will be your very own learning curve, then once you have gotten the smaller one operating right you can build a bigger more powerful one to make more power without any problems.

And some folks may want to build a small wind turbine since the larger ones possess some visual pollution for some people. But if you are not one of those individuals, then again the small wind turbine will be your starting ground till you having enough confidence to construct larger ones.

You can build a small wind turbine at home for less than $200 dollars or even less than $100 if you can find materials that don't cost much. Either way you can make one to save money on your electricity bill.

These costs consist of: complete UWT installation including the engineering, safety measures, monitoring, supporting construction, transport and mounting, proof of operation (commissioning) and the acceptance. Likely additional costs will arise from:

feasibility studies, location selection, structural assessments (if mounting the turbine on a building), obtaining permits and project management. In order to at least partially compare the investment costs of the different turbines, the cost per kW installed has been calculated. The figure provided is the result of: (total investment - remaining value after 10 years) / nominal capacity.

The remaining value has been estimated as 20% of the investment for all turbines except for Ropatec. This is because the manufacturer of Ropatec guarantees to buy back his turbine after ten years for a fixed price. However, it should be noted that all costs are estimates at the time of publication and could change.

Also, all calculations are only indicative, as the separately charged costs cannot be estimated and the performance figures provided by the suppliers and manufacturers have not been verified in practice. Therefore, although these figures provide a rough guide to costs, further investigation on an individual project basis is necessary.

4.1.2 Periodic costs

The periodic costs include maintenance, part replacements, transport costs related to the on-site work, the possible insurance costs (including the third party damage liability), the costs of any equipment replacements and the cost of a complete check of the system after 10 years of operation. Again, these costs have been estimated on the basis of information from suppliers and manufacturers and should be treated as indicative costs only.

4.2 Benefits

4.2.1 Financial incentives

The financial incentives available differ between the Netherlands and the UK.

The Netherlands: E.I.A. – Energy Investment Deduction for profit-making organisations: it is possible to obtain the E.I.A. with a maximum of € 5000 per turbine for turbines with a nominal power < 25 kW.

M.E.P. – Electricity Generation Environmental Quality: applies to the total energy generated by a renewable energy installation. The level of the M.E.P. subsidy per kWh is set by the government and laid out in the Ministerial grant scheme regulation.

UK: A grant can be obtained from the Low Carbon Building Programme (LCBP) in the UK, to cover up to 50% of the installation cost.

Some provinces and municipalities provide additional subsidies as a part of their own renewable energy development programmes. Most commonly these

subsidies are a part of local measures against climate change and are usually reconsidered yearly.

4.2.2 Savings through using of the generated electricity

Using the electricity generated at the location means direct savings for the owner through a lower electricity consumption bill. The savings depend on the price

paid to the electricity supplier by the consumer for electricity supplied from the grid. For example, the customers of the supplier ENECO in The Netherlands pay approximately 21 €cents/kWh. In the UK, typical cost of electricity for flats and households can range from 11p to 16p/kWh. These prices depend very much on the time during the day (or night) when the electricity is used.

Selling to the grid

If there is a surplus of electricity generated from a small wind turbine, in theory it can be sold and the owner decides to whom. Most commonly it would be sold to

an electricity supply company. The price can differ considerably from one electricity company to another, so it is worth investigating several options. For example, in the Netherlands, ENECO pays 4.088 €cents/kWh excluding VAT (2007).

The electricity supplier Green Choice gives discount on the supplied electricity to his customers who feed their energy surplus into the grid. Selling electricity to the grid is regulated differently in each country. If the owner of a UWT wants to sell his electricity to the grid, (s)he may need to have a specific type of meter that measures both ways: the electricity sold to the grid and the electricity consumed from the grid. This type of meter is readily available but is not installed as standard and so may need to be installed as part of the wind turbine installation.

4.3 Efficiency of UWTs

The efficiency of wind turbines is most commonly measured in terms of cost-effectiveness, i.e. in cost per kWh of the produced electricity. In a technical context in order to determine the revenue generating potential, the efficiency would be measured as a yield, measured as the number of kilowatt-hours produced per square meter of rotor area per year (kWh/m2/yr).

At this moment there are insufficient yield figures for UWTs from real projects to draw definitive conclusions on efficiency. This means that the efficiency can only

be estimated and that the comparisons between various types of UWTs cannot be done reliably.

Nevertheless, an indicative comparison is provided in Tables 4

and 5 by using the "reference yield" from the manufacturer calculated at two specific wind speeds namely:

o 12 m/s: a figure close to the nominal wind speeds of most UWTs

o 5.5 m/s: a good average wind speed for operation of the investigated UWTs.

Explanation:

A = rotor area

Vnom, Pnom en A have been provided by the vendors (see table 2). Pref is the result of the formula: Pref=(vref/vnom)3 x Pnom

Comparison with large turbines

The initial (capital) investment per kW can vary greatly between different UWTs: according to the information provided by suppliers and manufacturers it can be between 2,400 and 9,100 €/kW. In comparison, the initial investments for large turbines are about 1000 €/kW for land installations and about 2000 €/kW for offshore (investments in solar photovoltaic (PV) systems are approximately 6,200 €/kWp installed).

The expected yield, assuming there is an average wind speed of 5.5 m/s, would very approximately amount to 150 - 400 kWh/m2/year. The yield of large turbines

varies between 800 and 1200 kWh/m2/year.

The figures indicate that large turbines clearly outperform UWTs and this is not surprising, as the conditions under which they are implemented are very different.

However, UWTs are still in a development phase and although it is unlikely that they will ever reach the yields of large wind turbines (since wind resources are not the same in urban environments) it can be expected that costs will fall and the efficiency of UWTs will be significantly improved. Manufacturers of UWTs in the

Netherlands and the UK expect a price reduction of about 40% by a ramped-up production of at least 500 turbines per year.

Finally, UWTs generate electricity that can be directly consumed at the site of generation. This means that the produced electricity is effectively being used

against the consumer price which is approximately 5 times higher than the price paid for the electricity produced by large turbines.

Considering the installation capacity, costs and the expected yield, it is better to compare the UWTs with solar PV production of electricity.

Wind Turbine Generators.

There are many towers that are used with wind turbines and are typically relative to the amount of space you have and the budget available to the project.  Guyed lattice towers are the least expensive, and are easy to construct, but require a great deal of space to accommodate the down guy cables that attach to them at three different points to provide their stability.  A guyed lattice tower is usually constructed of steel angle iron and consists of three sides, which are shored up using cross sections that provide a ladder effect from top to bottom.

A tilt-up tower is constructed using metal tubing, is typically stabilized using 4 down guy cables and functions just as its name suggests.  The tilt-up feature of these towers is more convenient for maintenance purposes but a bit more expensive then the previous tower above.  The four-guyed cables are used to safely tilt the tower up from or down to the ground without the need for the tower to be climbed.  Monopoles are the most expensive towers used for wind turbines and usually seen on large wind farms, they consist of a single structured tube, which tapers in from the ground up.  Monopoles are the most aesthetically pleasing option for wind turbines but require the most amounts of steel, concrete and funds.

A small wind turbine for home use can be purchased or constructed.  The cost of a pre-made wind turbine can be a substantial investment and it is recommended to spend a period of time taking wind measurements using an anemometer before deciding to buy.  However, if you wish to construct your own wind turbine the cost can be reduced to only a few hundred dollars.  A wind turbine is a device which converts wind energy to electricity using a low-RPM generator, therefore the most important aspect of constructing your own hinges on finding a suitable generator which is capable of producing 30 volts at 300-350 RPMs or better.

The potential savings with wind turbines for home use can be particularly substantial.  With optimal conditions homeowners could see an 80% to 90% decrease in energy costs, but this is dependent upon consistent wind on the property.  Utilizing a wind turbine is a green option that many homeowners can greatly benefit from making it an attractive decision not only for energy conservation but for substantial potential savings on energy costs.

Wind Turbine Generators.

Just how much energy can a wind turbine produce, and will it really make a dent in your electric bill? First you must determine how windy it is where you are planning to install it. This is not a question about whether it is ever windy where you live, it is probably windy during storms, but that is merely an observation about the weather. What you want to know about is the long-term average wind speed for your area, or historic climate data, not day-to-day weather. Obviously it will produce a greater amount of energy the more the small turbine spins. They are defined as having rated capacities of up to 100 kilowatts. So if you were thinking that one wind generator will power your house, I'm  sorry but it won't.

Keep in mind that the wind turbine is simply a collector just like a solar panel is. In this case the collector is the spinning rotor, made up of a number of blades that rotate to turn the electrical generator. Small blades result in a small rotor diameter, which translates into a small collector area, which further translates into small amounts of generated electricity. To properly access the wind flow and generate enough electricity, wind turbines are installed on high towers that rise above any trees or surrounding buildings. Your roof top might not be the right place unless a tower is utilized. It is advisable to get your neighbors permission before installing such a structure. For whatever reason you chose not to have a high enough tower, it won't matter when it comes to generating adequate energy. It is better not to install a wind turbine in the first place, rather than to not have it high enough. There is simply little energy in low winds that you can convert into usable electricity. Considering that most homes do have more than one energy source, the average household consumes about  1,000 kWh of electricity per month, or about 12,000 kWh per year. Depending on your wind resource and the tower height required to get the wind turbine above the trees, a wind system designed to generate that kind of electric capacity would have to have a very large rotor. Even if you decided to go with several smaller wind turbines, the cost can be in the thousands.

There is of course another option that, depending on your situation, can save you thousands of dollars. I am referring to making this a do-it-yourself project. There are kits available that will cut your cost in half. Even better than that there are online instructional guides that will walk you through the entire process step by step. Small wind turbine system can be constructed for literally pennies on the dollar in this manner. For those of you who don't have either the time or the inclination to do it all yourself, I might suggest that you take advantage of the current work shortage by hiring a couple of competent handymen to construct the entire project. I bet with the right instructions, you could bring it in for a tenth of the original estimate.

My own extensive research has helped me narrow down the best of the best instructional guides, complete with blueprints, photos, for that do-it-yourself wind and/or solar power project you might be considering. Obviously, I can't go into great detail in this article, but if I have piqued your interest, you can get all the facts of this or many other ideas on how to go green at my site Possibly GREEN.

Wind Turbine Generators.

A couple of years back, wind energy companies saw the potential to make small scale wind turbines that can be installed at home. Many households jumped at the opportunity to make their own power and cut down on their monthly electricity bills. But the popularity of these turbine systems dropped as they were too expensive for the average income family.

Today, you can actually build a small scale turbine using simple and cheap materials that you can easily find in your garage or Home Depot store. You do not need any space age materials to build this free energy system.

For instance, you can build the turbine blades using a recycled PVC pipe that you can find in the scrap pile. In fact, I made mine using a decent length of PVC pipe I got from my local scrap yard for free.

Other parts such as the generator itself can also be bought easily from the Internet. eBay for instance is a great source of cheap and good DC motors that you can use on your homebuilt wind turbine.

With a well-written building plan in hand, you should be able to build a wind turbine small enough for you to erect in your backyard, but powerful enough to help run a few appliances at home.

ind generated electricity is a second option. The wind generator is a dynamo, a motor than converts mechanical energy into electricity which is connected to a turbine that is rotated by the force of the wind. In comparison with solar panels, wind turbines are more energy efficient even though, the wind turbine must be mounted in such a way as to be directed to where the wind is strongest. This maximizes electrical output.

The one major disadvantage is that solar panels and wind turbines do not produce electricity if there is no sunlight or wind respectively. Therefore, users will either have to rely on an external supply or store their generated energy in a battery.

There are several viable options for generating your own homemade electricity. There have to be decision made about the cost involved to buy solar panels or wind turbines as well as whether there will be a sufficient level of wind or sunshine to make the effort worthwhile. However, if enough people took on these technologies, the environmental impact of many Western countries would be significantly reduced.

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.

So what exactly is a small wind turbine. They are designed for individual homes, farms, and small businesses, and are electric generators that utilize wind energy to produce clean, emissions-free renewable power. They are defined as having rated capacities of up to 100 kilowatts. So if you were thinking that one wind generator will power your house, I'm  sorry but it won't. Keep in mind that the wind turbine is simply a collector just like a solar panel is. In this case the collector is the spinning rotor, made up of a number of blades that rotate to turn the electrical generator. Small blades result in a small rotor diameter, which translates into a small collector area, which further translates into small amounts of generated electricity.

Positioning is Very Important

To properly access the wind flow and generate enough electricity, wind turbines are installed on high towers that rise above any trees or surrounding buildings. Your roof top might not be the right place unless a tower is utilized. It is advisable to get your neighbors permission before installing such a structure. For whatever reason you chose not to have a high enough tower, it won't matter when it comes to generating adequate energy. It is better not to install a wind turbine in the first place, rather than to not have it high enough. There is simply little energy in low winds that you can convert into usable electricity.

Is it better to have many wind turbines or one larger one? To answer this question, you first have to determine what it is exactly that you plan to power. Are we talking about an all electric home, or perhaps one that uses other energy sources such as natural gas? Considering that most homes do have more than one energy source, the average household consumes about  1,000 kWh of electricity per month, or about 12,000 kWh per year. Depending on your wind resource and the tower height required to get the wind turbine above the trees, a wind system designed to generate that kind of electric capacity would have to have a very large rotor. The price tag could easily exceed $50,000.00 to install. Another option could be to have multiple smaller turbines. This of course would depend on the space you have available to erect the amount of towers needed.

Even if you decided to go with several smaller wind turbines, the cost could still run you about $12-$15,000. Yes it is a far cry from $50,000, but it is still a pretty penny. Depending of course what your electric bill is currently, you must determine how long it will take to pay for it. There is of course another option that, depending on your situation, can save you thousands of dollars. I am referring to making this a do-it-yourself project. There are kits available that will cut your cost in half. Even better than that there are online instructional guides that will walk you through the entire process step by step.

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.

Wind Turbine Generators.

This magical price reduction is the result of combining the now familiar 30% IRS energy tax credit with rebates from the Massachusetts Renewable Energy Trust (MRET). (Those of you living in other states can start here to investigate potential rebates, or call your state's version of the Department of Energy for more information).

Here's the way it works. The MSRP for the Honeywell turbine is around $4,500 and I've guesstimated installation costs at around $1,500 for a total of $6,000. I've low-balled the cost of install since it requires only bolting the turbine to your roof with pre-engineered hardware and wiring the all inclusive control package (inverter, etc.) to your home. If you decide to mount the turbine on a freestanding pole or tower the installation costs would be considerably more depending on the type and height of the tower.

Starting with the $6,000 estimated cost, we'll first deduct the 30% tax credit ($1,800) for a remainder of $4,200. From this we'll deduct $3,500 courtesy of MRET to arrive at the promised $700. The $3,500 MRET credit is the basic amount allowed for a small wind turbine rated at 2kW (kilowatts). On top of the $3,500, provisions have been made for additional rebates based on the turbine's subsequent verifiable power production.

In Massachusetts, the small wind rebate application is, by law, the responsibility of the installer. However, since the Honeywell turbine won't be available until October 1, 2009, I can't say for certain if it has been placed on the list of state approved turbines.

As of this writing, repeated phone calls and an email to MRET concerning the Honeywell's eligibility have not been returned.

Power Output

As I mentioned earlier, the Honeywell turbine it is being marketed as a 2,000 kW (kilowatt) generator. In other words, it is rated to produce 2000 kW over the course of a year, or approximately 166 kW per month - 18-20% of the average household's annual power usage. In order for their turbine to generate this amount of electricity, the 5.7' prop would have to encounter average wind speeds of 16 mph.

But, as any wind surveyor will tell you, there just isn't that much wind blowing down around the average urban/suburban home. The reason is too many buildings, trees, etc. obstructing the flow of wind and creating turbulence - the #1 enemy of wind power.

Of course there are exceptions. If you live in the central plains states you'll encounter a higher wind class owing to the lack of obstructions just mentioned.

Sure, you will get wind at very low altitudes, but in most cases the velocity and consistency won't match the manufacturer's predictions. At 15-18 feet (the height of a typical one story house) you would be hard pressed to encounter mean, average, or any other measurable wind speeds greater than 12 mph.

At 12 mph, a 5.7' prop (the diameter of the Honeywell) would generate approximately 67 kWh of electricity per month, or about 40% of what is claimed in the ads. At $0.12/kWh this would translate to an estimated annual energy savings of $96.

Availability

According to Earthtronics, the actual developer of the turbine, the units will be available at Ace Hardware Stores around the 1st of October, 2009.

When I visited the Ace Hardware website I found no mention of the Honeywell turbine so I contacted customer service. The very lovely and helpful gal who answered my call told me although the turbine would indeed be sold by Ace Hardware, it would be up to the individual franchisee to stock the item.

She further went on to give me a telephone number I could pass along to the owner of my local Ace store in case he or she didn't know how to order the turbine.

Executive Summary

Led by the growing photovoltaic market (PV), the outlook for inverters used in Alternative Energy Resource technology is expected to remain strong. Industry growth in this application will be driven by a combination of government incentives and declining PV module prices. Projected to make up over 95% of the market, the inverters used in PV installations, both small (1-5kW) and large (>6MW), will far outpace those used in either wind or fuel cell applications.

Driven by the need to develop alternative sources of energy, limit greenhouse gasses and reduce the dependence on foreign energy supplies, the market forces driving the alternative energy resources industry vary by region. In Europe, the primary driving forces are feed-in tariffs, which have been successfully used in 16 EU countries, most notably Germany, Italy and Spain. In fact, in Europe renewables comprise the fastest-growing segment of the energy market. In North America, unlike Europe, the alternative energy industry is driven by a combination of regulations, subsidies and tax incentives and legislation. In contrast, Asia employs a patchwork system of incentives including subsidies and other government actions. In this region, the primary focus on alternative energy is the alleviation of power shortages and the development of backup and emergency power.

A particularly significant technological and architectural trend includes the continued development of Building Integrated Photovoltaic (BIPV) systems. A BIPV system involves integrating photovoltaic modules into the building envelope material and power generators. Evidence of this can be seen in the number of successful BIPV projects worldwide, ranging from individual residential units to large commercial developments. . The development of BIPV systems is also significant because in buildings, it can play more roles than solely producing electricity. As an example, Sharp makes translucent solar PV panels that incorporate light-emitting diodes (LEDs) to provide illumination as
well as power.

The emergence of technology developed to address the problem of PV shading is another area of expected growth over the next several years. Considered one of the biggest challenges facing photovoltaics, a small amount of shade can lead to disproportionate power loss of more than 50%. One completely shaded cell can reduce a solar panel's output by as much as 75%. In a response to this challenge, a number of companies are developing products specifically designed to counter the effects of PV shading in both the residential and commercial sectors.

The move towards transformerless inverters has also made significant strides in the PV industry over the past several years. Despite concerns about safety, size limitations and the lack of technological maturity, they are considered considerably more efficient and can be produced at a much more competitive price. In fact, transformerless inverters continue to advance around the world and have achieved a global market share of about 70%. Additional developments in inverter technology include improvements in communications and monitoring and the trend towards longer warranties.

The trend towards more efficient inverters has also made considerable progress. In an effort to improve the efficiency of the technology, semiconductor companies are developing discrete IGBTs, MOSFETs such as CoolMOS as well as Silicon Carbide (SiC) devices in power modules and stacks, with the objective of raising solar inverter efficiency to 98 %, and with the purpose of feeding as much solar-based electricity into the power grid as possible. A number of semiconductor companies are developing technologies designed to increase efficiency and reduce electricity waste to a minimum.

Despite the efforts of a number of government and regulatory bodies worldwide, the goal of interconnection and regulatory standards is still a work in progress. However, there are
a number of groups working on electrical interconnection standards with the objective of reducing or removing barriers between distributed generation technology and the utility grid. A survey done found that most projects, including PV, wind and fuel cells, meet some sort of resistance from the utility companies when they try to interconnect with the grid. The expensive and sometimes difficult interconnection requirements currently in place worldwide comprise a key barrier to the increased use of alternative systems. One of the more interesting technologies being developed to drive interconnection is the development of a "smart grid." However, removing current interconnection requirements is not as simple as changing the policies, and a method of resolving these barriers is ongoing.

Despite the attention given to large multi-megawatt wind farms, which are projected to continue growing, both in size and number of installations, most of the opportunities for inverter manufacturers are in the small wind turbine market (<100kW). Although the market for wind power inverters is only a fraction of the size (<3%) of the PV market, the small wind market is experiencing a number of significant developments, including the emergence of Building Integrated Wind Energy (BIWE) and the further development of vertical axis wind turbines (VAWTs).

Although the smallest of the three applications presented in this report, fuel cells present another important opportunity for inverter manufacturers. Eighty percent of the fuel cell
units currently produced serve the stationary market in a number of capacities, including combined heat and power (CHP) applications, distributed generation on-site power and backup power. An especially important development is the FCC 07-107 requirement to provide eight hours of emergency backup power at remote terminals or wireless sites and 24 hours of power backup at central offices or switch sites. As a result of this FCC requirement, the telecom industry presents a promising growth opportunity for the fuel cell industry.

In addition, the rate of refurbishment and replacement of the existing building stock, combined with the new ultra-efficient housing/building laws such as those described in the European directive (2002/91/EC), contribute to a growing market for residential micro-combined heat and power. Fuel cells are an enabling or bridging technology which can allow the environmental and efficiency benefits of CHP to migrate into the residential market. In this respect, fuel cell technologies represent a market opportunity for the clean generation of electricity and provision of hot water and heating.

Wind Turbine Generators.

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.
