The turbine is a machine which converts rotational energy into usable work or usable energy. This change is initiated through mechanical gearing or because of electromagnetic induction, which results in electricity. There are different types of turbines including: steam turbines, gas turbines, water turbines and wind turbines, a source of energy is that is becoming more widely used. Wind turbines are powered by movement of air that propels the blades or rotors of the turbine, which are generally referred to as airfoils. They are designed to react with wind and capture energy. The shape of the blade causes pressure to be uneven, higher on one side than on the other, making the blade spin.
