Abstract

Direct-use geothermal systems represent a promising avenue for sustainable energy utilization, tapping into the Earth's natural heat reservoirs to provide heating, cooling, and other thermal applications. This paper explores the principles, applications, and advantages of direct-use geothermal systems, highlighting their role in mitigating climate change and promoting energy independence. The abstract begins by introducing the concept of direct-use geothermal systems, outlining how they differ from traditional geothermal power generation methods by directly utilizing the heat from underground reservoirs. It then delves into the various applications of direct-use geothermal systems, such as district heating, greenhouse heating, aquaculture, industrial processes, and spa resorts, showcasing their versatility across different sectors.
