Using Earth''s Energy: Can Geothermal Produce Electricity?

The mechanism behind electricity generation using geothermal energy is both innovative and efficient. Typically, geothermal plants utilise the heat to boil water, creating steam that then drives turbines. These turbines, in turn, activate generators, producing electricity. This process, while seemingly simple, leverages the Earth''s inherent ...

Electricity explained How electricity is generated

Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.
