Abstract : The following study has served the definition of geothermal energy and its application in any sort of field in an extended manner. In the study, some objectives have been developed depending on the subject matter. Also, secondary data has been collected by following the qualitative method which are directly related with subject matter. Later on, all the data has been collected depending on the subject matter. Primarily in this study, geothermal energy has been depicted as the renewable energy source of the earth. Also, there are several types of energy sources that have been showcased as the core part of the study. The usages of geothermal energy have been represented and the benefits have been showcased in an appropriate manner. Renewable and clean energy is produced with help of these geothermal energy sources. Gravitation and friction pull is also managed by this particular thermal energy. Thermal energy plants always try to maintain sustainability and environmental factors. Radioactive isotopes are also used by thermal energy planets to generate electricity. Geothermal energy pumps are used to collect energy. Pollution is also mitigated to produce electricity with help of thermal energy plants. These plants allow the demand of electricity to be fulfilled globally.
