Wind turbine design is a careful balance of cost, energy output, and fatigue life. Wind turbines convert wind energy to electrical energy for distribution. Conventional horizontal axis turbines can be divided into three components: • The rotor, which is approximately 20% of the wind turbine cost, includes the blades for converting wind energy to low-speed rotational energy.
