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 blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity. Diagram of wind turbine components
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. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
As the wind energy industry continues to grow, it will provide many opportunities for workers in search of new careers. These careers extend beyond the wind farm: it also takes the efforts of workers in factories and offices to build and operate a turbine. The wind energy industry has experienced rapid growth in the past decade.
