GEOTHERMAL ENERGY
Geothermal refers to producing energy from the internal heap of the earth. The internal heat of the earth is generated from radioactive decay of minerals and continual heat loss from the
Earth's original formation. So, Geothermal energy is a renewable energy source that is derived from the heat generated by the Earth's core. It is regarded as a clean and sustainable energy source that may be used for a variety of
functions such as power generating, heating, and cooling.
The Objectives of Geothermal Energy
Geothermal heat can be used to produce electricity in a geothermal power plant, so
electricity is generated when geothermal heat produces steam that turns turbines on a
generator.
How Does Geothermal Energy Works?
Geothermal wells are drilled into the Earth's crust at approximately a depth
of 3 to 10 kilometers. The heat is extracted with a variety of methods
but in most cases is drawn from the
earth using water and steam.
Hot water from the earth may be directly extracted to heat
homes and buildings, this is done either by directly
circulating the hot water through buildings or by pumping it through a heat exchanger that transfers the
heat to the building.
The major regions of geothermal
development are in the most volcanically and tectonic Lea active regions of the
world.
