[pdf] Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
[pdf] For the wind energy industry, wind direction sensors help optimize the performance of wind turbines. Knowing the wind direction helps operators turn the turbines to face the wind. This maximizes their power generation efficiency.
