A wind turbine converts wind energy into electricity by utilizing the aerodynamic force of the rotor blades, which function similarly to an airplane wing or helicopter rotor blade. When the wind blows across the blade, the air pressure on one side drops. Lift and drag are created by the difference in air pressure between the two sides of the blade. The lift force is greater than the drag force, causing the rotor to spin. The rotor is connected to the generator either directly (if it is a ... Wind power is a key component of the global energy transition, converting kinetic energy into clean electricity. As a renewable energy source, it is self-replenishing and produces no operational emissions, though the lifecycle of wind turbines presents its own environmental considerations. Learn the definition of wind energy, how it works, the different types of wind energy, pros and cons, and more. Learn how wind turbines use wind to make electricity, and explore the types, applications, and benefits of wind energy. Watch a video, see a wind turbine animation, and find more resources on wind power.
