Read More2023.10.19 Wind energy, or wind power, is created using a wind turbine, a device that channels the power of the wind to generate electricity. The wind blows the blades of the turbine, which are attached to a rotor. The rotor then spins a generator to create electricity. There are two types of wind turbines: the horizontal - axis wind turbines (HAWTs) and ...
