Because of both climate change and a rise in population, there is less fresh water available in a lot of different areas of the globe. This is causing a lot of problems. The ever-increasing need for energy is the primary motivating factor behind the global shift away from fossil fuels and towards renewable energy sources. Desalination plants will need to be constructed in large numbers all over the globe since freshwater resources are decreasing. Geothermal energy is one of these alternative energy sources that is currently being researched. While new desalination technologies are being developed, conventional methods are becoming more effective while also becoming less expensive. This page provides a summary of the many uses of geothermal energy found all around the world. It presents a specific scenario for desalination using a geothermal source, which has the potential to be free of both pollution and energy consumption at the same time. The benefits of geothermal desalination over other techniques, the present status of geothermal desalination around the globe, the method of choosing desalination technologies, and the challenges inherent in installing desalination systems powered by geothermal sources are extensively discussed in this article.
