Geothermal Energy Use explores the vast potential of geothermal energy as a renewable and sustainable energy source, examining its role in a future powered by clean energy. The book highlights how tapping into the Earth’s internal heat can offer a viable alternative to fossil fuels, while also acknowledging the challenges associated with its implementation. Did you know that geothermal energy has been utilized since ancient times, or that enhanced geothermal systems (EGS) are being developed to access geothermal resources in areas lacking natural hydrothermal activity? The book progresses from fundamental principles of earth sciences and geothermal resources to analyzing technologies like geothermal power plants and direct-use applications. It emphasizes the importance of understanding the geological foundations and environmental impacts of geothermal energy extraction. A balanced approach is maintained by addressing challenges like exploration risks and costs, alongside geothermal energy’s benefits, such as its reliability and minimal emissions. This book is unique in its comprehensive and accessible overview, making it valuable for students, researchers, and policymakers alike. By presenting case studies and data-driven analyses, the book promotes informed decision-making about the integration of geothermal technologies and environmental sustainability in various sectors.
