Geothermal field

The Earth's interior contains heat energy that comes from two different sources, one outside the earth and one inside the Earth. The Earth's temperature by the Earth's internal heat and gradually increase the impact of this heat from the Earth's interior known as“Internal heat.”. The increase in temperature per 100m or 1km underground is known as the geothermal heating rate, or geothermal gradient. Geothermal energy is stored underground and is not affected by climatic conditions. It can be used as either basic load energy or peak load energy. The equipment required is similar to a wellhead for oil and gas, except that it is for thermal energy. Compared with other renewable energy, geothermal energy has more development potential in terms of its development and utilization cost. As a clean energy, geothermal energy is attracting increasing attention all over the world.
