Building your own wind turbine from scrap materials is an excellent way to generate clean, renewable electricity and significantly reduce your energy costs. In this comprehensive guide, I will walk you through every step of the process, from designing and sourcing materials to construction and installation. With some basic DIY skills and a bit of perseverance, you can harness the power of the wind to produce electricity for your home.

Key Benefits of Building Your Own Wind Turbine

Siting and Sizing Your Wind Turbine

Choosing the optimal location and size for your DIY wind turbine is key to maximizing power generation. Here are some important factors to consider:


The higher the tower, the stronger and less turbulent the winds. Ideal sites are at least 30 feet above ground and obstacles. Consider elevated areas clear of objects like trees or buildings that could block wind.

Wind Speeds

Consistent annual wind speeds of at least 10 mph are recommended to justify a turbine installation. Use local wind maps to identify areas with suitable wind resources.

Turbine Size

Match the turbine size to your wind speeds and projected electricity usage. Most DIY models generate 1-5 kW. Calculate your needs and research the power curves of different turbine sizes.

Local Zoning Laws

Check with your municipal zoning department regarding ordinances for wind turbines and height restrictions for towers. Permits may be required.

Scavenging for Materials

One of the benefits of DIY wind turbines is that many components can be sourced cheaply or for free from junkyards and scrap yards. Useful materials to look out for include:

Also keep an eye out for spare wood, PVC, electrical components, metal sheeting, and tools that could aid construction. Get creative with your materials!

Key Wind Turbine Components

The main elements you will need to build your wind generator are:


Aerodynamically-shaped blades convert the kinetic energy of wind into rotational motion. Proper blade pitch helps maximize efficiency.


Contains magnets that spin around coils to produce alternating current (AC) electricity. Should match wind speeds and power needs.


Elevates and supports the turbine to capture stronger wind at increased height. The taller, the better.


Stores the generated electricity. Deep cycle batteries designed for solar systems work well.


Converts the AC power into usable DC electricity for your appliances and home grid. Match inverter to turbine power.


Regulates electrical load and monitors batteries to prevent overcharging. Keeps system running smoothly.

Step-by-Step Construction

Follow these key steps to assemble your wind generator:

Design the Turbine System

Build the Turbine Blades

Assemble the Nacelle

Erect the Tower

Install Electrical Components

Test and Troubleshoot

Obtaining Permits and Approvals

Most DIY wind turbines will require certain permissions and permits:

Final Tips

Constructing your own wind turbine is an ambitious but rewarding project that takes time and dedication. Here are some final pointers:
