How to build your own home wind generator?


A wind generator is one of the most effective ways to generate energy. It uses the wind’s power to rotate a motor and generate electricity through it. The world needs such inventions now more than ever. We are facing a major environmental crisis, and we should save as much energy as possible.

However, installing a personal wind generator may cost us fortunes. To spare you from that kind of financial pressure, we have come up with ways you can build your very own home wind generator.

What is a Wind Generator?

A wind generator, which is also called a wind turbine or a wind energy converter is a device that converts the kinetic energy of the wind into electrical energy.

There are wide ranges of wind generators available. While there are tiny wind generators that you can use to charge gadgets, there are larger ones as well that can power an entire house. Wind generators are also commonly used as auxiliary power for boats and even to power traffic lights.

The larger generators used as domestic power sources can even send the unused power back to the supplier through its electrical grid.

Wind generators are excellent replacements for energy-consuming power sources. It uses renewable resources and, thus, is very sustainable and eco-friendly. Many countries are now considering adopting this power supply system to reduce the use of fossil fuels.

How does a wind generator work?

Through three concurrent events, the wind, a form of solar energy, is formed. These events are:

  • The sun unevenly heating the atmosphere
  • Irregularities of the Earth’s surface
  • The rotation of the Earth

A wind generator uses aerodynamic force through its blades, which works like a helicopter rotor blade, to turn this wind energy into electric energy. The air pressure is decreased on one side of the blade when the wind blows through it.

Because there is a difference in the air pressure on the two sides of the wind generator blade, it creates a lift and drag situation. Here, the force of the drag is weaker than the lift because of which, the rotor starts to spin.

Then, the rotor sends energy to the generator. It may be direct if the generator is a direct drive or through a series of gears in case it consists of a gearbox. The gear causes the rotation of the blades to speed up and allow a physically smaller generator to produce power. In this way, the aerodynamic force transfers to rotate a generator, and the wind generator produces electricity.


Wind generators are highly beneficial and will provide us with a sustainable way to power our homes. To prove this point, here are the advantages of a wind generator.

Low in Costs

Many cities in the world do not have a sustainable source of power. They mostly use energy-consuming methods to generate electricity. Since this energy is non-renewable and has been scarce, the costs of consuming them are also very high. However, wind generators simply need the movement of air to generate power. It is available everywhere and hence, will not cost you fortunes.


The wind generator or windmill does not use any natural resources other than the wind. Hence, there is no possible way for it to overuse any non-renewable energy. It is highly environment-friendly and also very safe. Thus, it is sustainable, as well.


Like a large wind turbine, a small wind generator is also an immaculate source of energy. Since it only works based on the movement of the air, there is no possible way for it to be mixed or imperfect in any way. Moreover, these wind generators, because of its small size, can be located almost anywhere. We also ensure that it will not make any sort of disturbing noise.


Since this generator is tiny and will not weigh a lot, you can carry it anywhere. The lightweight will mainly serve you when you are traveling to remote places or camping. It can help you power your gadgets and, at the same time, provide energy to use for other purposes like lighting as well.

Power consuming areas

This DIY windmill is powerful and also portable. You should take advantage of that. You can find out how much energy parts of your house uses and, thus, reduce its use accordingly to conserve it.

The Making of Your Own Home Wind Generator

Gathering the tools

Make sure you collect all the required tools and components to build your wind generator. Make sure you have wire strippers and soldering irons. Also, collect recyclable materials like a 2-liter plastic soda bottle and their caps. You should also have light and thin strips of metal along with epoxy and glue.

Furthermore, get traditional tools like a saw, wrenches, and an electric drill to make sure you have everything around when you need them. Finally, make a construction plan before you start building your wind generator.

Constructing the catchment area

A wind catchment area is a component that collects the wind. To build this part, you will need the top parts of the plastic bottles. You saw the tops off below the neck from the 2-liter soda bottles. Then, use epoxy to join the bottle tops together. Fix them until you have four coupling components.

Building the fan

While this part is not exactly a fan, it will work similarly. To make this, carve an “X” of at least more than a foot long and an inch wide. Again, use the epoxy to fix the new fan with your couplets. Then, let the epoxy harden for a while.

Connecting the wind catchment and the fan

If you have designed and built your couplets accurately, this should not be a complicated step. Just screw the bottle tops into the couplets.

Constructing the generator

You now need to add the motor. This step is where you finally need the diodes and battery. Use epoxy again to fix the generator and the fan together. If there are any edges, fix them with glue.

Building the stand

Now, all you need to do is make a stand for your wind generator.

For this, you can build a stand based on what kind of motor you have used for your generator. However, a small rectangular piece of wood can be the ultimate stand for any home wind generator.

Completing the construction

Once you finish building the stand, carefully attach the generator and the fan to the stand. Make sure you keep the apparatus safe and stable as it should be able to withstand strong winds. To keep the generator fast, you can also use weighting mechanisms. As an alternative, we recommend you to go with 5kW or 10kW wind turbine for your house, farm, and water pumping use if you don’t feel like doing DIY. These 5kW/10kW wind turbine is affordable and used in small areas.

To sum up,

There you go! Now you can have your very own wind generator that you can use for generating power on your own. It barely costs you any money and is buildable within a fairly less amount of time. So, without any delay, start building your tower already!
