How do power stations generate electricity?
Production is carried out in power stations (also called “power plants”). Electricity is most often generated at a power plant by
electromechanical generators
, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind.
Which of the following parts of the geothermal power plant is responsible for the movement of the generator to produce electricity?
Geothermal Power Plants
Hot water is pumped from deep underground through a well under high pressure. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam. The steam spins
a turbine
, which is connected to a generator that produces electricity.
