How do turbines and generators produce electric power?

Turbines and generators work in tandem to convert various forms of energy into electricity through a process rooted in electromagnetic induction.

The Role of Turbines

A turbine acts as a prime mover, converting the energy from a moving fluid—such as water, steam, gas, or wind—into mechanical energy. This is achieved by directing the fluid through a system of blades attached to a rotor. As the fluid flows over these blades, it exerts a tangential force, or torque, causing the rotor to spin. This rotational motion provides the mechanical power necessary to drive a generator.12

The Role of Generators

An electric generator converts this mechanical energy into electricity. Most generators operate based on Faraday’s law of induction, which states that an electromotive force is induced in a circuit by a varying magnetic flux. By using the rotating shaft of a turbine to spin magnets or coils of wire, the generator creates a changing magnetic field. This variation induces an electric current, which is then transmitted for use in homes and industries.3415
