How to Build a Small Scale Wind Turbine from Scrap Materials


Building a small scale wind turbine from scrap materials can be a fun and rewarding project. Wind turbines harness the power of the wind to generate electricity. While commercial wind turbines can be enormous, building a small scale wind turbine at home is totally possible with the right materials and ingenuity.

In this guide, I will walk through the full process of building a homemade wind turbine from start to finish using scrap and recycled materials. With some creativity and elbow grease, you can build an electricity-generating wind turbine even on a limited budget.

Planning Your Wind Turbine Design

The first step is to plan out the design for your wind turbine. Here are the key factors to consider:

Size and Scale



Electrical Generation

Building the Frame and Blades

The frame and blades give the turbine its distinctive windmill shape. This provides the surface area to catch wind energy.



Adding Rotation and Electrical Components

You'll need some key mechanical parts to enable turbine rotation and electricity generation.

Rotating Mechanism

Alternator or DC Motor


Mounting, Testing, and Applications

The final steps are mounting your turbine for use and troubleshooting any issues.





Building a homemade wind turbine from scrap materials is an achievable and engaging renewable energy project. With some upfront planning and scavenging for parts, you can construct a functioning turbine even on a tight budget. The flexibility to adapt parts and experiment with different designs makes wind turbines a great scrap project. Just take it slow, do your research, and have fun with the hands-on learning process!
