The increasing world population also raises energy demand. As a result of continually using fossil energy, carbon emissions increased, which is the main factor causing global warming. Over the past years, many efforts have been made to reduce the carbon emission produced by energy, searching for green future energy which has sustainability, environmentally friendly, and clean energy. Geothermal Energy is one of the alternatives that has been explored and researched accordingly. Sustainable development calls for the use of sustainable energy systems. The world’s geothermal energy resources should be used in sustainable activity, which means that it is produced and used for the well-being of future generations and the environment. This paper reviews the connection between geothermal energy development, sustainable development, and future green energy. Previous publications related to geothermal, sustainability and green energy in journals indexed by Scopus were collected, mapped, and reviewed to provide a comprehensive recommendation. Then, semi-structured interviews with experts were conducted to validate the finding of this work. The results show that the impact occurred as a result of geothermal energy development for electricity generation, which can be positive or negative. The need for proper management of such impact follows a sustainability assessment process identified for geothermal energy development is built in this paper. Finally, gaps and future directions were summarized at the end of this paper. This paper contributes to fundamental knowledge introduced herein, which can inspire researchers to detect gaps and serve to motivate the high potential of utilizing a clean and sustainable source.
