Geothermal energy may provide a dependable and sustainable answer to Bangladesh's increasing energy needs while mitigating the effects of climate change. This research emphasizes base-load supply, power output, and environmental advantages and explores Bangladesh's potential for geothermal energy development. A 200 MW project has already been approved in Thakurgaon and Habiganj. Titas, Shabajpur, and Thakurgaon are potential geothermal hotspots. In light of Bangladesh's distinct geological circumstances, the research examines the viability of geothermal power-generating methods such as binary cycles, flash steam, and dry steam. Additionally covered is the potential for enhanced geothermal systems (EGS) to have a lower environmental effect and greater efficacy.   Geothermal energy can be critical in diversifying Bangladesh's energy mix, ensuring energy security, and supporting decarbonization efforts. However, careful management of environmental and social impacts is essential to fully harness geothermal energy’s potential. This study provides a foundation for future research and policy development to optimize geothermal energy utilization in Bangladesh.
