Alternative sources of energy become quite popular today. There are a plenty of different types of power mechanisms which are able to accumulate enough energy using natural endless resources. One of them is a wind turbine.
This eco-friendly mechanism will power a house regardless of the weather conditions or any other factor. The home wind turbine will work at night when it is rainy, cloudy, etc. the only thing required is wind which is pretty enough on the open space.
This device is a really great way to start charging you gadgets and power your home, in general, using an alternative source of energy. Just think: one 25m height turbine is able to power a house and the 80m one can produce such amount of electricity which is enough to power hundreds of houses. Moreover, this is a good chance to get rid of paying taxes for usage of the traditional electrical grid.

There are several wind turbine types but all of them have similar principles of work. The wind blows moving blades which produce and transfer power to an electrical generator which produces the energy and supplies it to the grid. Let’s overview some basic components without which work of the wind turbine is impossible:
Power generator – is needed for charging batteries. Its capacity influences the time is required for charging your accumulators. Voltage and amperage of the generator depending on the wind stability and speed.
Rotor blades – capture the wind and transfer its kinetic power to the rotor hub making it move.
Tower – passive but one of the essential components of the structure. The higher is the tower, the more stable and strong is the wind and the more power will we get.
Of course, there are rather more components which are also important for normal both horizontal and vertical wind turbines. All of them you can see in the picture below.
How electricity generates
As was said above, wind turbines have quite a simple principle of work. So, let’s consider it in detail. The power producing process begins when the wind blows to the blades. This makes them turn around the rotor hub which is connected to the main shaft. The latest transfers kinetic energy to other components which control and maintain the needed capacity of the energy. Finally, it gets to the generator which produces electricity. In the picture, you can also see the way the power comes through from the rotor hub and up to the generator.
The wind direction may always change, so modern turbines are equipped with special automatic turning system which identifies a side the wind blows from and turns in front. Such a feature helps to catch much more wind and to produce as rather more amount of the power.
Types of wind turbines
The horizontal axis and Vertical axis
There are two basic wind turbine types: horizontal and vertical axis. The horizontal one has a traditional form and structure which are rather widely used than the second one. The horizontal axis means that the rotating mechanism is set in parallel to the ground. In most cases it has two or three blades set on the top of the tower, however, a number of them may be different depending on models.
The more blades, the more wind they can receive and the less rotating speed the device need to produce a given amount of energy. Two or three-bladed turbine will have to rotate much faster than, e.g. multi-blade one to reach the same capacity.
However, most owners prefer three-blade horizontal turbine because they think that a lot of blades usually impede each other’s work. So, wind-consuming is not effective enough as it is expected to be.
The vertical wind turbine has another structure. Its rotating mechanism is established perpendicularly to the ground which causes changing most of the general blade building characteristics of the turbine. Usually, these devices have long, arc-shaped blades. In this case, wind direction does no matter. Blades catch the wind regardless of where does it blow and there is no need to turn the rotor towards the tight side. Despite different structures, both of the times have similar composition and working principle.
Wind turbines can also differ by the way of the wind interaction. Means fixed or movable blades. Both types have their individual pros and cons. For example, fix-blade turbines are more flexible and sensitive to the wind so they can produce more power due to the proper adapting to the wind direction and speed. But they have one serious disadvantage – movability is provided by bearings which quite often cause breaks. Turbines with the fixed blades are more robust but the efficiency of the wind flow use is much lower.
Roof mounted and Pole mounted
There are two ways to use wind turbine for a home to provide all the gadgets of the house with the green energy. The first of them is to set a pole mounted turbine. This is a traditional way of usage. As it was mentioned above, the higher is the pole, the more energy will be produced.
The second residential wind turbine type is a roof mounted one. To make the blades as high as it is possible you don’t need to buy the pole. You can simply set the windmill on the top of your house. Moreover, you can spend the money saved from buying pole on additional windmills to use several ones for having more power!
While looking for such an alternative source of power as a wind turbine generator important is to buy the appropriate one which will be able to produce enough energy according to your needs and field of application in general. There are lots of factors which the right choice depends on. One of them is the turbine’s capacity. This parameter depends on the amount of energy that you regularly consume in your normal everyday living.
Furthermore, the weather in place you live also has influence. It has to be windy enough to make the turbine work properly and start producing the needed level of the energy. But if the wind is too strong and the blades are rotating faster than it is allowed the rotor can be damaged. Most models are equipped with an automatic braking system which ensures the mechanism from extremely strong wind blows. Nevertheless, we advise having a professional consultation before purchasing this device.
To ease your research, we have collected and compared several wind turbine generators of different brands with various advantages and other essential characteristics like capacity, weight, etc. So, you can easily find the needed one.

Advantages of using a wind turbine
- Economy. First of all, using a wind turbine is cost-effective. Spend some money just at once and get a source of free electricity for many years. With this, you will significantly decrease your electricity bills or even forget about them at all.
- Mitigating future energy price rises. Using green energy and economizing electricity now we prevent not only energy but also general prices rise in the future.
- Reducing your carbon footprint. For supplying houses through traditional electricity grid power plants emit thousands of tons of carbon in the atmosphere. Using the wind energy, we decrease demand on traditional power and participate in the protection of the environment.
- Electric stability. Wind is endless and one of the most effective eco source of power of now existing. Provide your house with constant power supplies regardless of the weather conditions. Most of the windmills have a low starting speed and even if there is a calm outside, you can use an additional battery to charge it and use whenever you need.
Is a wind turbine right for me and areas of use?
Before buying and installing the wind turbine generator we have to pay attention to some factors which will tell us whether it is possible or not. In most of the cases, it appears that the location is not coming for installation.
- Wind speed – where to look. One of the essential factors which influence high windmill operating performance is the wind speed. The stronger it blows, the more power will you get. If you live in the area where annual average wind speed is not less than four meters per second (about 9 MPH), then you can buy the turbine without any hesitation. On the internet, you can look for your regional average wind speed.
- A place for installation. You need to have enough space in your area to install the home wind turbine. There don’t have to be any barriers which may stop or redirect the wind not allowing him reaching the blades. If there are trees or other houses, settle the turbine on that height which will above the top of trees.
- Things to avoid and obstacles. Turbines can make some noise and some of them are really loud. So it is better to have enough space in your area to choose the appropriate distance between the turbine and your house.
Wind turbine Installation and maintenance
In spite of that, the residential wind turbine is quite a useful and value for money device, it demands regular servicing. There several movable parts which constantly operate. So checking their condition from time to time is the best way to make your turbine live longer and show high performance.
We recommend you to build annual schedule according to which you will conduct planned checks of the turbine’s components. Don’t wait until the heavy wind comes and destroy or damage the construction. Better is to verify whether everything is ok or not beforehand. Some devices have complicated structure and in this case is better to call professionals which will help you to maintain your generator.
On average most of the turbines are designed for 20 years of normal operating. If the wasn’t too strong winds and turbulence, which appear because of inappropriate location a windmill, the turbine will work up to 25 years or even more. The only condition is the needed level of regular service which prevents breaks and makes the tool lasting much longer.
If you ask whether it is worthy to buy a residential wind turbine or not? The answer is – definitely yes! The wind generator usage is one of the most cost-effective and reliable ways of getting alternative energy absolutely for free. Just pay at once and consume your own electricity produced from the wind for more than 20 years. This is an eco-friendly way to decrease amounts in your electricity bills and provide your house with green power.
