The water heats up to nearly 400 degrees Fahrenheit (200 degrees Celsius) before returning to the surface. Once there, it transfers its heat to another liquid with a low boiling point, creating steam. The pressure of steam expanding spins a turbine to produce electricity like in a coal or natural gasfired plant.
