Blade length of high mountain wind turbine
At 351 feet, the blades for GE’s Haliade-X 12MW wind turbine are the world’s longest. It is impressive as an engineering feat, but the significance of growing turbine size goes well beyond that.

In 2023, the average rotor diameter of newly-installed wind turbines was over 133.8 meters (~438 feet)—longer than a football field, or about as tall as the Great Pyramid of Giza. Larger rotor diameters allow wind turbines to sweep more area, capture more wind, and produce more electricity.
The review provides a complete picture of wind turbine blade design and shows the dominance of modern turbines almost exclusive use of horizontal axis rotors. The aerodynamic design principles for a modern wind turbine blade are detailed, including blade plan shape/quantity, aerofoil selection and optimal attack angles.
A detailed review of the current state-of-art for wind turbine blade design is presented, including theoretical maximum efficiency, propulsion, practical efficiency, HAWT blade design, and.
Wind energy has undergone a massive transformation, represented by the colossal blades propelling turbines into the future of renewable power. From modest beginnings with blades a mere 26 feet long, today’s wind turbines showcase blades surpassing 350 feet—the breadth of a football field.
