Geothermal energy, as one of the renewable energies, has a significant contribution to global energy production. This energy is defined as the extraction of thermal energy from the underlying layers of the earth, and unlike other renewable energies, it is not limited to the season, time, and conditions, and can be exploited without interruption. Heat transfer in such systems is carried out by a hot fluid, which is available in underground hot water reservoirs. Researchers have found that areas containing warm underground water are rare and in many places water is not available to exploit its thermal energy. This heat penetrates into the rocks at low water points and causes very high temperatures. The method of extracting energy from hot stones in these areas is called improved geothermal energy. This paper tries to summarize the improved geothermal energy, the location of this energy in the world, its benefits and, ultimately, some of the world's most important projects, including the Los Alamos project as one of the first projects in the use of Examine the improved geothermal energy.
