What is geothermal energy

Geothermal Energy (Geothermal Energy) is the natural heat energy extracted from the earth's crust. This energy comes from the lava inside the earth and exists in the form of heat, which is the energy that causes volcanic eruptions and earthquakes. The temperature inside the earth is as high as 7000°C, and at a depth of 80 to 100 miles, the temperature drops to 650 to 1200°C. Through the flow of groundwater and the lava flowing to the crust 1 to 5 kilometers above the ground, heat can be transferred closer to the ground. The hot lava rocks heat the nearby groundwater, and these heated water eventually seep out of the ground. The simplest and most cost-effective way to use geothermal energy is to directly use these heat sources and extract their energy. Geothermal energy is a renewable resource.
