Wind moves the blades of a windmill by transferring its kinetic energy to the blades. As the wind blows, it imparts force to the blades, causing them to rotate. The rotating blades then drive machinery or generators to produce electricity.

Wind moves the blades of a windmill through the principle of aerodynamics. The shape of the windmill blades is designed like an airfoil, with a curved surface. As the wind flows over the blades, it creates areas of high and low pressure. The pressure difference results in a lift force, similar to the lift on an airplane wing. This lift force causes the blades to rotate. The wind’s kinetic energy is thus converted into mechanical energy, turning the rotor connected to a generator, producing electricity. The design ensures optimal utilization of wind energy to generate power in a sustainable manner.
