1. How to harness the wind.
2. How to convert that wind into electricity.

How to Harness the Wind:

Obviously, you must first harness, or capture, the power of the wind. Wind usually flows or blows forward over the ground's surface. So this lateral motion must be changed to a rotary movement. As with a windmill, this is accomplished with angled and tilted blades.

Since the blades must always face directly into the wind, the turbine has a device that forces the blades to remain in place as the wind changes direction. A tail fin that resembles those on an aircraft is placed behind the blades, and it keeps them in proper position as the wind blows. As the wind changes direction, the force exerted on the sides of the tail fin ensure that the blades stay in place.

When the wind hits the turbine's blades laterally, their angled and tilted design converts it to a sideways motion; then the spindle that anchors the blades helps to form a rotary movement.

How to Convert Wind into Electricity:

Now that we know the turbine's blades continually face the wind and create rotation, we need to see how electricity is produced. As we said, the blades are attached to a center spindle. This spindle connects to an axle, and it usually drives a gearbox to speed the blades' rotation.

The axle servers as a conduit to a generator. The generator basically converts the rotating wind into electrical energy. Since this article only explains the operation of a wind turbine generally, we won't describe the physics of what occurs - it just does!

Simply put, that is how it happens. We then have free electrical power, courtesy of the wind. The only other thing you have to do is use cables to connect the generator's output to your home. You can further save on your electric bill by adding circuits to regulate voltage and batteries to store any excess power.

Final Thoughts and a Note About Safety:

Now you know basically how wind turbines operate and how they can create free electricity for your home. But you must consider some other issues before you install a wind turbine. You can do some online research to find more information.

Be sure to contact an electrician before you make any changes to your home's electrical supply.

That being said, many people are wondering if there is really a possibility to power a home or small business with renewable solar energy. The answer is yes, you most certainly can. Actually, you would save a great deal of money by using a renewable energy source to power your home. Since renewable energy's rise in popularity over recent years, it has become more and more feasible that you can find supplies to get started with this venture. It has also become quite simple to find information on how to build the equipment yourself for a solar or wind powered generator. Handymen and DIYers are in a position to save thousands of dollars annually by building these structures personally rather than hiring a specialist or purchasing an already manufactured unit. Generally speaking, homemade units are a little less efficient, but the money saved on installation can help you see a quicker return.

As with all technology, renewable energy is evolving and becoming more advanced, efficient, and affordable as time passes. Solar energy used to run from huge rooftop mechanisms, but is now produced with a thin microfilm which is doubly efficient. Solar powered charges for your cellphone or small home appliances are now readily available. Even windmills have been redesigned to maximize aerodynamics and increase productivity. Many highways are now powered with renewable solar and wind energy fueling traffic lights and roadside signs.

Renewable energy is a viable resource that you can use to power your home or business. Renewable energy resources are becoming increasingly common, and could benefit the world by reducing the effects is global warming as well as our dependance on fossil fuels.

The sun is the most obvious and popular of the green energy sources.  Energy that is derived from the sun for our use is called solar energy. Because solar energy has numerous uses, it is among the most popular and widely used sources. In order to convert solar energy into usable energy for your home or business, solar panels are constructed with structures called photovoltaic cells. These cells capture the energy from the sun and convert it into electricity you can use. In addition to producing electricity, energy from the sun can be used to heat water. There are special devices called solar hot water collectors which use the heat of the sun to produce hot water. Solar panels and solar hot water collectors are green energy sources that are widely available and can be purchased by most homes and businesses. These devices can be easily mounted on rooftops and owners can begin to see a reduction in their utility costs almost immediately.

A second green energy source is the wind. The wind is the most efficient of the green energy sources. In addition to powering water pumps for centuries, wind energy has recently grown in popularity as a supplemental energy source for homes and businesses. Because wind produces no pollutants and does not contribute to global warming, it is the safest and cleanliest of the green energy sources. In order to generate wind energy, strong turbines are erected in locations where the breeze can be used to their advantage, thereby generating wind energy. While solar energy can be accessed from almost anywhere, it is difficult to use wind energy as a green energy source unless you live in an area where wind is readily available.

A third green energy source is none other than water. While water has long been a source of green energy, it is not practical for all homeowners or business owners to use water as an energy source because they may not have access to a stream or body of water which is needed to produce electricity. And while the Amish cannot use traditional electricity to power their tools or shops, they have successfully used the energy from water to power the conveyor belt systems that they use in their shops today. Water energy is very advantageous, because like solar and wind energy, it is virtually free of chemicals and is a completely renewable energy source.

There are several reasons to utilize green energy, including lowering our dependence on fossil fuels, reducing our monthly budget, and lessening the negative effects of global warming. If you want to save money and extend the life of our Earth, consider investing in green energy sources for your home and business today.

You can execute your green energy home plan in a variety of ways. The use of solar energy is the first way to convert to a green energy home. Installing solar hot water panels, which will heat your water and store it for later use, as well as converting sunlight to electricity with photovoltaic cells on solar panels, are two ways beneficial elements of a green energy home. Attempting to purchase one of these systems would be quite an expensive endeavor, however, there are a variety of resources that allow you to build your own solar hot water or solar panel system at a fraction of the cost.

You can make your brand new home a green energy home by figuring passive solar design into your plans as you construct your home. Utilizing south facing sides of the home will maximize your heating and cooling efficiency. You can take advantage of passive solar methods by including many energy efficient windows on your home's south facing side, as well as the use of heat retaining bricks and stone, which will be extremely useful in expanding the benefits of your green energy home.

A windmill is another advantageous element that can be added to a green energy home. Harnessing the power of wind allows the windmill to generate electricity. You may choose to install your windmill on your roof, or stand it in your yard, but either way you will be generating electricity that is pollution free. In your quest for a green energy home, you can buy a windmill from a retailer, or for the individual who can handle those do-it-yourself projects, there are reasonably priced kits available.

Hydroelectric power is another great addition to your green energy home if your property includes a stream. With the presence of water, you have the opportunity to generate another pollution free, low maintenance option.

Utilizing all of the mentioned resources in unison, will create the most efficient, superior green energy home.  The benefits of producing your electricity through the use of wind, water, and solar are immense, including great savings and maybe even profits based on your electricity usage, and you can be as green as it gets since all of your power generating options do little to add to global warming. With each new addition to your green energy home plan, you are further decreasing your need for energy and walking the walk of "going green".

You will find that there is no more upkeep needed on your green energy home, then on a traditional home. You will perform only routine oiling of your wind and water turbines to ensure superior performance, and solar technologies require little or no attention. Begin to live your green dreams by getting started on your green energy home today!

The best starting point for building your own wind turbines is to begin by purchasing an instruction manual. You should keep in mind when shopping for instructions that you do get what you pay for. You should select a manual that is easy to read, with plenty of details included on the instructions. There are many options to choose from thanks to the many online resources and forums that are dedicated to helping people build their own wind turbines.

Before you begin construction on your own wind turbines, you should understand the four basic components to wind turbines. Wind turbines consist of towers, batters, the turbines themselves, and the tail and propeller. The tools needed to build your own wind turbines are actually rather simple, they include wrenches, saw and a drill. There may be additional tools that you need depending on the specific design of the wind turbine you select.

One part that you will probably not be able to build yourself and will have to order is the motor. Keep in mind that the motors on wind turbines require regular maintenance, including oiling, to keep them running smoothly but this is a small price to pay to break your current energy dependence and start saving on your utility bills. You will also need a large workspace for the assembly of the unit. Keep in mind that your blades could be 4 feet blades, which means that your total diameter across the unit could be just over 8 feet.

It will take some work to complete the construction of your own wind turbine, but it is not difficult, and will pay for itself through the energy savings you will be enjoying over the coming years. Building wind turbines is also a growing field as the interest in them grows and they becoming more common. Therefore, learning how to build wind turbines yourself can be a valuable asset in addition to the benefits of free electricity and reducing your carbon footprint.

You might be asking the question, "why should I build a wind generator when I can just buy one?"  But the problem with this scenario is that a commercial wind generator will come with a price tag in the thousands. In order to build a wind generator on your own, you will need these reasonably priced items: DC motor, batteries, towers and hub. For less than $500, you can build a wind generator, and with the power that you will be saving, you will recoup that investment much faster than you could ever hope to if you purchased a commercial wind generator and had it professionally installed. You will be able to stay well below the cost of a purchased wind generator, even if you select premium quality materials to build a wind generator.

You will have tapped in to one of the top choices for highly productive renewable power, by generating your electric power by using the wind as a resource. It has become common in places around the globe, to begin to add to their energy supply through the use of wind generation. When you decide to build a wind generator, you are contributing to the establishment of a green energy supply. It's great to realize a savings with generating power this way, and additionally, you are becoming an advocate for conservation.

To build a wind generator is actually not a challenging task at all. An individual with general do-it-yourself skills, and basic tools, will certainly be able to build a wind generator. You will be able to use the available specific instructions and plans to build a wind generator right in your own home or workshop. So, now is the perfect time to build your wind generator, attach it to your roof or to a support pole, and with a small breeze, you will be producing your own free power in no time!

As demands for renewable energy technology increase, more efficient components have been developed to make living off the grid a reasonable option for those who can commit to conserving their energy use.

Producing electricity with renewable energy sources is actually pretty simple. First, you need a power source -- sun, wind, or water -- from which you will harness a low-voltage direct current, which is then converted into house current (AC). If your system generates excess current it is stored in battery banks, where it can be retrieved for high-demand situations, or for instances when the direct energy sources are not available.

Not only that, living off the grid with renewable power resources is practically fully-automated. Except for keeping your batteries up-to-date, there isn't anything special you need to do other than keeping track of your energy use to be sure your supply and demand don't exceed each other. So successfully living off the grid requires a large enough system to meet your energy needs.

It can be exhilarating to live off the grid! Knowing that you are free from energy needs is a feeling like no other, and you can be proud of your role in the battle against global warming. Also, you may never need to worry about power outages again. Just be sure you have done all the necessary research and have found the best alternative energy resources for your situation and for your geographical location. And remember - learning how to live off the grid and feeling the rush of freedom it can give is definitely worthwhile.

Before installing a DIY wind power generator, it must be kept in mind that the site or area where you are going to erect the turbine is crucial to the flow of energy. Thus the key concept here is to get the most out of the wind turbine by erecting it in a suitable place. To detect wind speeds in hilly areas, an anemometer will be required. In plain areas, it is not necessary.

These tools can come in handy. Wind energy maps can be gathered from the nearest department of energy or even by searching the web. Keep in mind if there are a lot of trees around, how high you plan to erect the turbine, etc. Large obstacles like buildings are best kept away from as they diminish the flow of wind.

2. Check into local laws to be sure you have permission to build.

In some cities wind turbines have not yet been legalized. In other areas government employees are open to the technology and are more eager to lend help. States such as New Hampshire have special regulations you must follow. In addition, there may be a permit fee.

3. It is good to get the gist of the project before starting installation of the DIY wind power generator.

Many beginners are making this mistake knowingly or unknowingly. If you are an electrical engineer then you may be able to wing it but others new to building must be careful to do the proper research reading before marching.
Many of the tutorials available online are not worth following. Be careful when you choose online manuals and DVDs on how to install wind turbines. Here is a comparison of the best DIY guides to get your started.

4. For ready-made turbines, get to know the product and seller.

Suppose you bought a ready-made DIY wind turbine and you have no technical support. How are you going to resolves issues you may come across?

Be sure the company you are buying from has a 1-800 number. You may want to try out their number and get some information before shopping to be sure they have a responsive staff.

The e-mail support team may answer the request is too late and so it is good to have a few other options as you are going to invest your valuable money into this.

The main reason to assemble a wind turbine yourself is to save money but make sure your unit does not get left behind into the garage. If things get hairy, you can always find a company to install it for you.

5. Are you not clear about the type of warranty they are offering?

Some people don’t read up about the warranty on products and pay the price later. See what terms are addressed, such as “any defects found in” or “the product will be replaced or refurbished at the expense of the seller” etc.
There are provisions that the seller has to refurbish or replace the whole product in case found non-working at the arrival time. Ask about the conditions when you receive the defected items at your door and not a couple of months later.

6. Are you not talking to DIY wind turbine owners, mostly neighbors already?

These are the people who can tell all the good and bad about the product they are already using. It is a great help before buying a wind turbine of your own.

In many situations the best way to learn about the law provisions is by approaching your closest neighbors. If you fill in the legal forms wisely no grouchy neighbors can file complaints. Still, try to be considerate about noise levels so everyone is happy.
Another place to look online is yahoo groups; here you can find people who are building themselves and also others installing DIY wind power turbines.

If your area isn’t very windy, your current power supply can still be fortified with renewable wind energy. Even if you don't consider yourself a handy person, you can easily build your own windmill with a DIY guide and immediately enjoy the cost-reducing benefits of renewable wind energy. And the windier your area, the more power renewable wind energy systems can provide you.

You can even power your renewable energy system by building a wind turbine. Entire cities have been powered in full or in part by wind farms. Perhaps excessive for a single home, but a few small wind turbines can pack a lot of power. Your renewable wind energy system may even enable you to sell your surplus electricity back to the power company.

Another big advantage of wind energy use in your home or business is that it is Earth friendly. Pollution and greenhouse gas emissions are minimalized or eliminated. Renewable wind energy eventually pays for itself with what a homeowner saves.

Take some time to research renewable wind energy. You can benefit your budget and be green with your own wind turbines. Sustainable, renewable wind energy. Courtesy of the wind. Has a nice ring to it.

Many supporters of homemade wind turbine generators have been able to cut down electricity bills by 80%. Some even produce enough excess energy to get paid by the power company. The only negative point of such a system is the modest amount of noise it makes. This is good news for the green living movement.

Here are five of the main steps that can help you build a wind power turbine of your own:

1. Suitable Location

Choice of location is a must. The area you plan to erect the turbine on must not have a lot of trees around, buildings or any other type of obstacle that can slow down the speed of the free moving wind. It is best to choose flat-topped hills because the wind is stronger at higher lands. In short, more wind means more energy.

2. Place to Mount

Now that the site is chosen, the next thing to do is to mount the system either on the rooftop or on a tall pole type mast a little further from the house. It can be something like the TV antenna tower. Before mounting, you must clear up all the legal obligations that may create problems in the future.

3. Size of Turbine

The next consideration is the power of the turbine and compatibility issues. The power refers to the capacity in wattage that it is going to generate after the installation. For a normal house a 600 watts turbine will be enough to power lighting and general electricity needs. For making all of the appliances run from the wind power, you are going to need a power output of 1000 watts. Thus the capacity also depends on how much you are going to use it.

4. Back Up Source of Power

Situations like varying wind strength cannot be avoided, sometimes even leading to temporarily system collapse. To avoid problematic conditions in the future, there must be some sort of back up plan. One of the easiest ways to create a backup is to keep additional storage batteries to run the house for a few days till the wind power turbine is repaired. Another good back up can be solar panels that absorb the energy from the sun to charge up batteries.

In some cases, there are provisions that the power company provides you with for an on grid and off grid application installed in your home. In the case your homemade wind power turbine goes temporarily out of commission, you can just call the company and they will connect you with power immediately.

5. Detailed Guide with Illustrations and Videos

It is essential to do the right homework before installing a wind turbine. Those that follow shoddy plans end up with a less efficient system. So, coming to an understanding of installation and management will help you on the long run. Browsing the Internet to collect tutorials and videos with the necessary graphical illustrations can be burdensome.

You can download the best step-by-step guides online. Make sure that you do some research before jumping to any hasty conclusions and buy just any kind of guide available. For the best guide, check that the cost estimation of installation is not more that $300; Stick to easily accessible hardware materials you can get at any store nearby.

Neighbors who have their homemade wind power turbine installed already may have some advice so it doesn’t hurt to ask. Once you feel confident enough to begin building, move carefully one step at a time and be prepared to be precise.
