Abstract: Modern technology civilization, yet rapidly growing dependence on the world, ends with increased demand for energy consumption. An increasing aim of creating a sustainable environment involves the careful use of energy sources. The use of renewable energy resources to improve the performance of current technology and thus economically proper use of energy are three important strategies in addressing those concerns. Geothermal energy is a renewable source of energy with the ability to generate a fair amount of the world's natural hot electricity, heating, and cooling. In all volcanoes, geysers, and the low enthalpy types, it occurs in high enthalpy where the warmth in the crust is contained in rocks. The current research explores the direct use of energy through the ORC method worldwide and the future planning of these prospects for renewable sources of energy. Different nations use heat energy directly in many ways and discuss in particular the generation of electricity over the last twenty years and their future projects. In addition, technology's environmental impact and economic viability are mapped. Recent studies support the advantages and limitations of technology and opportunities for improvement. Briefly, the study discusses the potential role of geothermal technology in an extremely sustainable future. Finally, for further investigation, the likely subjects of future research will be presented.
