A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.

Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn.

The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller.

Unlike fans, which use electricity to move air, wind turbines use moving air to generate electricity. When the wind blows, its force turns the blades, which runs a generator and creates clean electricity. But some turbine designs can produce more clean energy than others.

What is energy in the wind?

energy is in the wind. First we distinguish between conce ts of power and energy. Power is he time-rate of energy. For example, we will need to know how much energy can be generated by a win turbine per unit time. On a more homely front, the power of the wind is the rate of wind energy flow hrough an open window. W

Why is wind power so powerful?
