Geothermal Energy Definition
Geothermal Energy Definition. It is generated during the formation of the planet. There are two sources of earth's heat, or geothermal energy:
The leftover heat from the formation of. The word geothermal comes from the greek words geo (earth) and therme (heat). Geothermal energy is heat within the earth.
Geothermal Energy Is Heat That Is Generated Within The Earth.
With responsible exploration and utilisation, geothermal energy is an environmentally friendly and sustainable energy source. The temperature gradient may sometimes reach over 4000 °c. It can provide energy around the clock, what we call a baseload capacity.
Deep Underground, The Earth Will Remain Hot For Billions Of Years, So Geothermal Energy Can Be Used For A Long Time (As A Renewable Energy Source), But If The Resource Is Not Treated Carefully, It Will Not Be Sustainable.
We put the terms together in the word geothermal to describe heat coming from the earth. Heat from earth’s interior generates surface phenomena such as lava flows, geysers, fumaroles, hot springs, and mud pots. It is a challenge to estimate power from this source since it occurs underground at extremely high temperatures.

This process is continuous and it never stops, this is why geothermal energy is a renewable energy source. The earth’s crust has immense heat (thermal) energy stored over millions of years. Energy obtained by tapping underground reservoirs of heat, usually near volcanoes or other hot spots on the surface of the earth.
It Comes From Heat Generated During The Original Formation Of The Planet And The Radioactive Decay Of Materials.
The hot steam from a geyser and the hot lava from a volcanoe are examples of geothermal energy because they both come from the underground. A typical well doublet (extraction and injection wells) in nevada can support 4.5 megawatts (mw) and costs about $10 million to drill, with a 20% failure rate. State two disadvantages of geothermal energy.
It Can Be Used Directly For Heat Or To Create Electricity.
The geothermal gradient is the driving force for the continuous conduction of thermal energy in the form of heat from the core to the surface. Geothermal energy—energy derived from the heat of the earth—can be harnessed both as a source of renewable electricity as well as directly for heating and cooling applications. Geothermal energy = earth heat this is a clean renewable source of energy which provides energy in households the world.
