How wind turbines work

Wind turbines basically consist of a high tower with rotors at its top that turn. To ensure wind generates as much movement as possible, the following typical design has prevailed since the 1980s: three long rotor blades are attached at equal distance from one another to the nacelle at the top of a long tower. The rotor blades are aerodynamically shaped and positioned in such a
