What is Wind Energy?
Wind energy is the conversion of the kinetic energy of moving air into usable electricity, using turbines. These systems harness natural wind currents and turn them into mechanical power, which is then transformed into electrical energy.
How Wind Energy Works
- Wind Meets Blades
The rotor blades are shaped like airplane wings—when wind blows past them, it creates pressure differences that generate lift, causing the blades to spin.
- Rotation Powers the Generator
The spinning blades turn a shaft, which may go through a gearbox (or connect directly) to rotate the generator. Inside, this mechanical movement induces electricity via electromagnetic principles.
- Directed for Optimal Efficiency
Control systems like the wind vane and yaw motor constantly orient the turbine to face the wind. Blade pitch is adjusted to maintain ideal speed and safety thresholds.
- From DC to AC & Beyond
The generated electricity—usually AC—is stepped up by transformers and sent through the grid to power homes, businesses, and industries.
Cost Comparison: Solar PV vs Wind Energy
