The global demand for sustainable and clean energy sources has driven significant advancements in the field of geothermal energy. This paper provides a comprehensive review of the latest technological developments and environmental impacts associated with the advancement of geothermal energy. Technological developments in geothermal energy have focused on enhancing efficiency, scalability, and cost-effectiveness. Innovations in drilling techniques, such as enhanced geothermal systems (EGS), have expanded the potential for harnessing geothermal resources in previously untapped regions. Furthermore, advancements in materials science and reservoir management techniques have contributed to increased energy extraction and prolonged reservoir life. This review also delves into the environmental impacts of geothermal energy, addressing both the positive and negative aspects. Geothermal power generation produces minimal greenhouse gas emissions compared to traditional fossil fuels, contributing to a cleaner and more sustainable energy landscape. However, concerns about induced seismicity, subsurface fluid management, and the potential release of trace gases during geothermal operations require careful consideration. The integration of geothermal energy into the broader energy mix is explored, emphasizing its role in reducing reliance on fossil fuels and mitigating climate change. Additionally, the review discusses the importance of regulatory frameworks and community engagement in ensuring responsible geothermal development. This paper highlights the dynamic landscape of geothermal energy, showcasing the progress made in technology and the environmental considerations that accompany its expansion. As the world seeks alternative energy sources to address climate change and energy security, understanding the evolving nature of geothermal energy is crucial for informed decision-making and sustainable energy transitions.
