A large, utility-scale turbine may have blades over 165 feet (50 meters) long, thus the diameter of the rotor is over 325 feet (100 meters)

How do wind turbine blades work?

Spin the shaft and you will notice it produces a voltage. So just attach a blade to it, and it’ll spin in the wind and generate electricity. The speed of the wind increases the higher we go and it’s also less turbulent. The larger the blades, the more wind energy we can capture. Large blades need to be higher off the ground.

What are wind turbine blades made of?

Forty years ago, wind turbine blades were only 26 feet long and made of fiberglass and resin . Today, blades can be 351 feet, longer than the height of the Statue of Liberty, and produce 15,000 kW of power. Modern blades are made from carbon-fiber and can withstand more stress due to higher strength properties.
