turbine Rotary device turned by a moving fluid (liquid or gas). The modern form of water turbine is like a many-bladed propeller and is used to generate hydroelectricity. In power stations that burn fuels to produce electricity, the energy released by the burning is harnessed by the blades of jet engine-like steam turbines. As they spin, the turbines turn generators that produce electricity. Modern wind generators produce electricity when the wind turns their rotors. In gas turbines, hot gases from burning fuel turn turbines that can operate generators or other machinery.
