A Turbine is an internal combustion unit that is driven by the pressure of steam, water, air, etc., against the curved vanes of a wheel or set of wheels attached to a drive shaft.
In the environment context, a "turbine" is a mechanical device that converts the energy from a fluid, such as water or air, into rotational energy, which can then be used to generate electricity. There are several types of turbines, each designed to extract energy from a specific fluid.
An example of a turbine in the environment context is a wind turbine, which converts the kinetic energy of the wind into electricity. Wind turbines typically consist of a tower, a rotor with blades, and a generator. When the wind blows, it causes the blades to rotate, which in turn drives the generator to produce electricity.
Another example of a turbine in the environment context is a hydro turbine, which converts the kinetic energy of flowing water into electricity. Hydro turbines typically consist of a turbine runner, a turbine casing, and a generator. When water flows through the turbine, it causes the runner to rotate, which in turn drives the generator to produce electricity.
Both wind and hydro turbine are renewable energy sources and play an important role in reducing greenhouse gas emissions and combating climate change.
