Wind Turbine Power

Wind Turbine Power | Science Fair Projects | STEM Projects
Wind turbines are a great way to generate electricity without burning fossil fuels. In this project, you'll explore how the angle of the blades affects the amount of electricity generated.


The hypothesis is that the power generated by the wind turbine will vary depending on the angle at which the blades are positioned.

Method & Materials

You will build a wind turbine with blades at different angles, measure the voltage generated, and observe how the angle affects the power output.
You will need a DC motor, a zinc sheet, scissors, wooden blocks, an electric hand drill, needle files, a protractor, screws, a screw driver, a digital voltmeter, and an industrial fan.


The results show that increasing the angle of the wind turbine blades up to 75° will increase the output voltage. Beyond 75° the output voltage will decrease. This proves that the power generated by the wind turbine does vary depending on the angle at which the blades are positioned.

Why do this project?

This science project is interesting because it explores how to generate electricity from the wind in an environmentally friendly way.

Also Consider

Experiment variations include using blades of different sizes and varying the wind speed to observe any differences in the results.
