Homemade Wind Turbine – What You Need Know

Many eco-friendly and do-it-yourself enthusiasts looking to use wind for a renewable energy source will create a homemade wind turbine to meet their energy needs. With this renewable energy source, they can meet their demands and sell back the extra resource to the utility company.

You might think it’ll take you forever to learn how to build wind turbines but, in reality, it’s rather easy to do. You can either buy a kit set that you can assemble together or begin from scratch and construct the tower, generator and use appropriate wood to shape the windmill blades.

Do Your Research Before You Begin The Project

It’s always best to do some research into the site you would like to put your turbine on. This is more important than what kind of materials you want your turbine to be made out of. When you’re choosing the site, check out the wind atlas information online and/or measure the prevailing winds with the help of a small wind meter for several months. This information should tell you where you should and should not place your windmill.

Another thing you need to do before you make a homemade wind turbine is an audit of your home’s energy usage. How much will you be saving by using a renewable energy source? This should be done before you choose the power capacity and start building the wind turbine.

Parts Of A Wind Turbine – What You Need

Now, to make a homemade wind turbine, you’re going to need several things. You’re going to need a strong roof or structure that can support the blades of the device, a connection that attaches to the generator, the tail assembly that ensures that unit will stay facing the wind and other various electrical equipment pieces.

A wind power turbine project is something the entire family can get involved with. After all, the more hands involved with it means the quicker the job can get done. This type of project can take mere days to put together. After all, once you got the parts together, you need just a limited amount of electrical knowledge to help you get it correct. If you wish to have a surplus of energy you can sell back, then you’ll need qualified electricians to help you out.

One Drawback To Using A Homemade Wind Turbine

There is one drawback; the energy you generate needs to be stored in a battery so that it’s slowly released when the wind dies down. The reason this is such a drawback is that the batteries can cause problems for the environment when you need to dispose of them. Of course, that doesn’t mean that technology for wind power can’t improve; it does everyday.

How To Build A Homemade Wind Turbine – What Does It all Mean (In The End)

If you’re looking to build wind turbines, you should know that it’s not all about putting the device up and watching your electrical bill fall. What you should learn from all this is that wind energy turbines are great for the planet and is a very effective solution.

A modern homemade turbine is very efficient, making it a very exciting power source for the future. Any person who chooses to build a homemade wind turbine will get an endless supply of energy that requires nearly no maintenance whatsoever.

If you want to stop using fossil fuel electricity and go to a renewable energy source like wind power, consider learning the steps to make a homemade wind turbine right now.

Residential Wind Turbines – Tower and Roof Mounted Minimum Requirements

There are two types of Residential Wind Turbines, (also called wind generators), tower mounted or roof mounted, with the minimum requirements for both tower and roof mounted wind generators being an uninterrupted wind speed.

Tower Mounted Wind Generators – Minimum Requirements

  • Consistent wind above 8 mph, (13 kp/h)
  • Minimum tower height of 30 ft, (9 m)
  • No significant obstacles within 500 ft, (152.4 m)
  • Have at least one acre of available land

The minimum requirements for a tower mounted generator is an uninterrupted wind speed of at least 8 miles an hour, (mph), (13 kp/h), a tower that is at least 30 feet high, (9 m), (the tower can be as high as 150 ft, (46 m), (depending on the wind conditions).

The home should be on at least one acre land that also has no significant obstacles within 500 ft, (152.4 m), of the wind power tower, that would disrupt the airflow.

Of course, this makes tower mounted wind generators only realistic in rural areas, and that is generally the only place you will see tower mounted wind turbines.

Roof Mounted Wind Generators

For many years roof mounted wind generators have been the poor sibling, the most obvious reason being the requirement for a minimum, uninterrupted air flow, but you also have to add in the cost of the wind turbine itself, which can be significant, (and with the older models there are additional the costs because you have to remodel the roof to support the additional weight), also, the old technology rooftop wind turbines were noisy, and prone to vibration.

With those requirements it would be almost impossible to get a city or suburban permit to install a wind power system on your roof.

Blade Tip Wind Turbines – Minimum Requirements

  • Consistent wind above 2 mph, (3.2 km/h)
  • Start-up speed of only 0.5 mph, (0.8 km/h)
  • Blade-tip to blade-tip diameter of only 6 feet, (2 m)
  • A wind site survey should be done before installation

There is now a new breed of wind generators, which starts from a simple idea that is now set to revolutionize rooftop wind turbines in city and suburban centers.

This revolutionary technology is more efficient, compact and lightweight, will not require a remodeling of the roof, require less maintenance and a pay back time in as little as five years, depending on government rebates.

This is done by eliminating the normal gear system, drive shaft and DC power generator typically found in traditional wind generators.

Instead, the blade tip wind turbine power system places the magnets and stators, (that produce the electricity), on the inside of the wind turbine rim, at the blade tip, where the blades spin fastest, thereby creating the most energy per revolution possible.

This one step reduces the blades start-up speed to just 2 mph, the weight and size of the wind turbine is also reduced to less than 200 lbs, and 6 feet across while the design also significantly reduces the noise and vibration, making these systems “permit ready”, and available to both city and suburbs alike.

Nevertheless, some basic requirements still have to be met for residential wind generators to make economic sense.

For instance, if residential wind generators are to be mounted on the rooftop of your house, you have to ensure that there is sufficient, consistent wind where you want to place the wind power system, this is done through a wind site survey, indeed the manufacturer will require that this wind survey is done before they will proceed with installation.

Because of the simplicity of design these new residential, “Blade Tip”, wind energy systems are significantly less expensive to install and maintain, with a payback period in as little as 5 years.

Wind Turbines: Small – Scale Versus Large -Scale Wind Turbines

You can run (on an average basis) twelve volt appliances within a particular structure when you install small wind turbine equipment. Equipment in your home or other smaller buildings can be used without the consumption of any alternate fuel, electrical charge etc. As a matter of fact, wind turbines are completely natural – absolutely no energy is wasted and none is gobbled up by the usual electrical resources or any other kind of fuels.

When you make an effort to conserve energy, you contribute to the effort of protecting our planet – which millions have begun to realize – is vital for our survival. We live in the clutches of an earth which we truly are destroying. Many people all over the have begun to join as virtually some kind of crusade. When you are one such person, you are definitely helping improve the overall condition of the world we live in.

Some people believe that without an elaborate system there is no way to create an effective wind turbine for his or her home – this is a great falsehood. Especially in particular parts of the country or land where wind generation is simple, people have been using wind longer than you may think. Believe it or not, there are actually places where mid – scale wind turbines are completely relied on for all power generation and distribution.

Wind turbines have been useful for the function of household electricity generation for years. Wind power is usually generated in conjunction with battery storage in remote areas such as villages and farm towns. Therefore, new wind power generations systems are only improvements on a theory already proven to work in small areas for decades.

Grid – connected wind turbines are able to function as grid – energy storage equipment. Off – grid systems may adapt to intermittent energy, power. Or perhaps they use photovoltaic or diesel systems to supplement wind turbines, either way – wind turbines are a good thing to consider for yourself if you care for environmental preservation.

Even in urban locations where it is difficult to obtain and maintain large amounts of wind power, one can nonetheless utilize smaller structures of wind turbines. Smaller systems of wind power equipment can always be used for smaller, low – powered equipment.

In addition to low – powered equipment, small wind turbines can collect and generate backup power. These wind turbines will also assist in the distribution of energy in the house or structure of this nature. Wind turbines are as small as four – hundred watt generators (for home – use, primarily) to long streams of elaborately constructed turbines to generate power for much more powerful purposes.

Small — scale wind turbines are usually about seven feet in diameter and they produce approximately 900 watts of energy. The wind turbine structures are lightweight, extremely, as a matter of fact. They weigh only about thirty – five pounds and are mounted upon a house similarly to a television radar dish.

There is actually a significant advantage to small wind turbines as opposed to large scale wind turbines. At least, in means of cost and installation, the reason for this is because of what researchers call the “square cube law.” Capturing more accurately and effectively the amount of wind it is designed to collect. In the simplest terms the design is more elementary and absolutely less costly. Scientists have to put much more consideration into the path of wind, the collection of wind, the size of the turbines and / or wind power collection for large – scale wind power farms.

Essentially, the creation of a large scale wind turbine is a proposition that would require much more funding, research and expertise. The simple, low cost installation of wind turbines for small locations such as homes, (or even smaller, remote locations) is more logical at this time.

However, large – scale wind farms are important to consider. If more and more people begin to use small – scale wind power structures there will certainly be a transformation in the amount of electricity they decide use. However, if this phenomenon became a popular one in many private homes and buildings, it may enhance the federal notions towards funding larger – scale wind farms in the long run.

Micro Wind Turbine – A Great Renewable Energy Solution

For years demand for renewable energy solutions has been on the rise. Wind farms have been set up across the UK, both on land and off shore. At the same time solar energy has taken centre stage with thousands of homes across the UK incorporating solar energy into their house designs in order to reduce their carbon footprint and energy bills.

One of the renewable energy sources that isn’t as popular in homes across the UK is the micro wind turbine. These wind turbines catch the wind and then convert the wind to electricity, often storing the electricity in a battery for when it is needed.

A micro wind turbine can be astandalone unit also called a freestanding turbine or a roof mounted turbine. With over forty percent of the wind in Europe coming through Britain, it is a surprise that these turbines are not being incorporated into homes as much as they should be.

The reason homes choose renewable energy is to reduce their carbon footprint, reduce their energy costs and do their bit for the environment. This can all be achieved through the wind turbines available.

With the governments “feed in tariff” scheme, homes which benefit from renewable energy are paid by the electricity companies for using their own power, they are also paid money if they transport some of their energy into the grid, which is then used to power other properties in the area.

So what are the choices when looking for a renewable energy solution for your home? The most popular is solar energy. Solar energy uses energy produced by the sun and converts that into electricity which is then used in the home.

While solar energy remains a top choice with homeowners throughout the UK, the UK doesn’t benefit from much sunshine each year. The solar panels are positioned in a way to maximise sun exposure and they do capture some of the energy even when it’s overcast.

With this in mind, it’s becoming apparent that wind energy is a great solution. Most of the time there is a breeze blowing across the UK. In fact forty percent of the wind in Europe passes over the UK, that means the micro wind turbine will benefit from energy throughout the year, even when it’s snowing and sleeting.

These turbines are very easy to understand. The turbine consists of blades which when caught in the wind start to spin, that spinning motion creates friction which is converted to energy and stored in a battery. The advantage to the micro wind turbine is that energy in the battery can be stored for days when there is no wind, ensuring the home always benefits from renewable energy throughout the year.

Another advantage to the micro wind turbine is how easy it is to install. Solar panels can take a day or more to install properly. The panels need to be mounted on the roof where they can gain maximum sun exposure, where a simple wind test in your area can determine the best positioning for a micro wind turbine and it can be installed within a number of hours.

It is advisable to have your area tested regarding wind speeds before choosing your micro wind turbine. You want to gain the best possible results from your turbine, so positioning is as important as the turbine you choose to power your home.

Once the micro wind turbine has been installed, the home can benefit from renewable energy that can power the home throughout the year, reducing your carbon footprint, reducing energy costs and enabling you to make money back from the grid.

How to Obtain the Best Wind Turbine Plans

If you are searching for your own personal wind turbine, then you must get a solid set of wind turbine plans to aid you during this period. This is very essential in the beginning because even the smallest things can impact how your wind generator functions. The secret to dealing with renewable energy is to make it as efficient as possible so that it will be beneficial without being expensive.

Many times people will ask me where beginning wind power enthusiasts should start. Well, there are a lot of choices for wind generator plans which include wind turbine kits, commercial products and do it yourself manuals that will all basically provide the same outcome. But, your preferences and expectations are what will really matter. What type of outcome do you expect to get from your investment? What is going to be the icing on the cake for you?

Start Slowly

One of the most common problems that I have discovered about people who are just starting out is that they use a set of wind turbine plans that are much too complex for people just starting out. It is interesting to read the online stories about how a person put together a 1000 Watt wind generator that is functioning well for them. But the truth is that the people who build these complex wind turbines are more experienced users. So it is hard for a new person to see and comprehend the design details.

Many times this creates tons of stress and makes people want to give up. In addition it ends up wasting a lot of time and money. I do not want to say that it is not possible to build this type of wind generator, but they are much simpler when you put down the foundation and then understand the details of the project that you are about to get into.

A majority of people start with an easy set of wind turbine plans. This is really the smart and most viable thing to do. It is helpful to put down the foundation that you can grow and then move your work to a higher ground. But, without this groundwork, it will not be successful.

Quality if Important

I also want to stress that there are different types of quality when it comes to wind turbine plans. A few plans are crafted and are understandable by the person who created them, but totally elusive to the person who is reading them. But on the flip side, there are other plans that have proven to be effective and crafted in such a manner that anybody will be able to follow the basic concepts.

Premium wind energy manuals will also have plenty of graphics, flow charts and examples of the things that are in them. A majority of people learn by looking at the pictures and these pictures can be the difference between learning the process and giving up.

Some of the plan developers now include video guidelines with their wind turbine plans in order to ensure that you receive even more detailed information.

The Greatest Wind Turbine Plans that are Available

I think that the greatest wind turbine plans are the ones that give you the most for your investment when it comes to the actual plans as well as the price that goes into producing your wind turbine. I also think that it makes more sense to teach a person how to do something as opposed to doing it for him.

This is why I only make recommendations for a few of the better do it yourself wind turbine plans on the market. These plans provide complete instruction on how to produce easy wind generator for about one hundred dollars. This is not a lot of money when it comes to wind generator plans. Many times they also are available with video instruction, which can give you a whole lot more details than standard guidelines. You will have to pay for these wind turbine plans, but they are affordable when you take into consideration that money will be saved on parts in the long run.

When you use these plans and understand how wind turbines work and how to create one the right way, it will be easy to scale it up and get the same outcome that a lot of the more seasoned users are experiencing.

How Does a Wind Turbine Generate Electricity?

With so many ecological threats we face today, the concept of wind energy is gradually gaining a strong footing. It is imperative now to give due credence to such renewable sources of energy.

Wind is basically the movement of air, which depends on the sun. Solar heating patterns on the surface of the earth create this phenomenon. Different land and water bodies on our planet’s surface absorb the sun’s heat at varied rates at different times of the day; for e.g. during the day, the air over land surfaces heat faster than over water. On expanding, this warm air rises with cooler, denser air replacing it, creating a movement known as wind. During the night we see the reverse of this pattern. Geographical location, vegetation density and the intensity of solar heat are also some of contributors in wind creation. When in motion, the air has copious amounts of resulting energy that can be gainfully used in various forms and for various purposes.

Thus the wind is not only something pleasant you look forward to on a balmy day, but can be one of the most effective forms of energy creation, when harnessed correctly. Since it depends on the sun, wind power or energy is a renewable and ‘green’ way to power our world. It can be used to create or supplement electricity and mechanical power.

The vital cog in the process of wind energy usage and creation for the generation of power, are the Wind Turbines. These turbines employ the mechanics of a reverse fan. Powered by the wind’s energy, its blades help in generating electricity. The basic mechanics consist of the turbine’s blades that are put into motion by the wind, and are connected to generators. Finally, these generators are used to transform this rotational energy into electric power.

How they work:

Turbines typically have two or three blades. Even in a wind-less situation, the blades on a wind turbine are positioned at an angle of 45 degrees so that the turbine can trap all possible energy even with the slightest of winds. When in contact with the wind, the fronts of the rotor blades (which have the larger surface area) propel to a 0 degree angle and are bombarded with energy, from the front and the back. In essence, this creates positive pressure on the fronts of the blades and negative pressure behind them, causing a suction type effect which in turns lifts the blades and transfers the wind energy to kinetic energy. This force turns the shaft connected to the rotors, creating a strong rotational energy which gets converted to electric energy by the generators.

An electric control system connects the generator. The entire system channels the produced electric energy to high voltage transformers and eventually the grid. These grids are responsible for supplying energy to places like homes, farms, factories, water pumps, as well as commercial power suppliers.

The efficiency of wind turbines depends on various factors such as location, geographical factors, mechanics, rotor shape/size, etc… Output can be regulated by a constant or variable rotational speed, as well as adjustable and non-adjustable blades. This control is essential because sometimes the wind’s speed puts too much stress on the turbine, causing safety controls to kick-in and apply brakes to the rotor to prevent it from damage.

Types of Wind Turbines:

Wind turbines can be classified into two major types. Although they work on the same basic premise, the process and design differ greatly.

Horizontal Axis Wind Turbine (HAWT): Horizontal axis wind turbines are more widely used and are the more traditional style in turbine design, mostly seen in wind farms. These are generally used to power electrical generators, because of the usage of gearboxes which enable change in rotation speed. Efficiency of a HAWT is generally high because of the angles the blades are set at, a blade pitch that is adjustable and the height of the tower (as greater wind speeds are found higher up from the ground, higher towers typically capture more wind energy). A horizontal turbine therefore is mainly run by a system of blades/rotors, a generator, a gearbox, the shaft and a supporting tower.

Vertical Axis Wind Turbine (VAWT): Vertical axis wind turbines, as the name suggests, consist of a vertically arranged rotor shaft. This is also known as the ‘egg beater’ style. A vertical axis wind turbine has proven to be very useful at locations where the wind direction tends to vary. This type of turbine however, is said to be not as reliable and efficient as a HAWT, one of the reasons being the low placement of the rotors.
