How does geothermal power work?

Geothermal power or earth power is the electrical energy that can be generated from earth energy. Geothermal power is a renewable energy source that can be used again and again but will still be available for many years to come as geothermal energy gets replenished inside the earth.

Geothermal power plants can be used to generate earth power by using geothermal power products. A geothermal plant is the one that converts the geothermal energy into useful electrical energy that can be used for both domestic and commercial purposes.

To obtain the geothermal power products like hot water from geothermal reservoirs, a well is drilled. Once the hot water is available, it is converted to steam that can be used in a geothermal power plant to rotate the blades of a turbine. The rotation of blades of the turbine powers generator that converts the geothermal energy in the steam that rotated the turbines into geothermal power or electricity.

The use of earth power in the working of geothermal power plants is clean and environment friendly. It does not cause any pollution and also does not add any harmful particles to the atmosphere and so can be safely used as a green renewable energy source. Geothermal power products can help in cost effective generation of electricity in a reliable manner so as to provide electricity that is readily available for use whenever required.

The installation of geothermal power plants is very expensive and therefore, earth power has not been fully utilized for the generation of electricity.
