Due to the gradual decay and radioactivity of the elements in the Earth’s core, this part of the Earth’s body always has a temperature of about 5000 degrees Celsius. The heat flow created in the Earth’s core and mantle is constantly flowing, and this heat flow has a high thermal conductivity. Under the earth’s crust, molten mantle currents move as convective currents and contain high heat energy that needs to be extracted. The average heat flux that reaches the earth’s surface is about 16 kilowatts of heat energy per square kilometer, and over time, if not exploited, this heat is dispersed into the atmosphere and space. This heat flux flows along the boundaries of the Earth’s crustal tectonic plates more strongly than elsewhere. Volcanic activity transports hot matter to the earth’s surface, but only a small fraction of this molten material actually reaches the surface, and the rest remain at depths of 5 to 20 km below the earth’s surface. Hydrological convection can create high temperature geothermal systems at depths of 500 to 3000 meters under the ground. Companies that are active in the field of sustainable energy can exploit this sustainable energy source by using appropriate technology and equipment.

Some of the most important advantages of a geothermal energy source are:
