How many blades does a 68-meter wind turbine have
The United States Department of Energy reports that most modern land-based wind turbines have blades of over 170 feet (52 meters), resulting in a total rotor diameter longer than a football field. [PDF Version]FAQs about How many blades does a 68-meter wind turbine have
How big are the blades of a wind turbine?
For an average 1.5 MW turbine, the blades are between 35 to 45 meters. This gives an average rotor diameter of around 75 to 100 meters.

How do wind turbine blades generate electricity
A wind turbine generates electricity by using the kinetic energy of wind to spin its blades, which are connected to a rotor. The generator then converts this mechanical energy into electrical energy. [PDF Version]
How much electricity does a wind turbine generate per rotation
How much power a turbine produces can be derived using the following formula: Power (P) = 0. 5 × Air Density (ρ) × Swept Area (A) × Wind Speed³ (v³) × Efficiency (Cp). [PDF Version]
