Introduction

Geothermal energy stands at the forefront of sustainable energy solutions, leveraging the Earth's internal heat to generate electricity and provide direct heating and cooling. As the global community intensifies efforts to mitigate climate change and transition towards renewable energy sources, geothermal energy emerges as a promising avenue due to its abundant, reliable, and environmentally friendly characteristics [1].

This introduction explores the concept of geothermal energy, tracing its historical evolution from ancient civilizations' use of hot springs to modern technological advancements in harnessing deeper reservoirs of heat. Unlike fossil fuels, which contribute significantly to greenhouse gas emissions and environmental degradation, geothermal energy offers a renewable alternative that operates with minimal carbon footprint and water consumption.

The significance of geothermal energy extends beyond electricity generation to include direct applications in heating buildings, greenhouse agriculture, and industrial processes, thereby offering versatility in addressing energy demands across various sectors [2]. This section will delve into the types of geothermal resources, global distribution, and the technological processes involved in extracting and utilizing this natural heat source efficiently.

Furthermore, this introduction sets the stage for a comprehensive exploration of geothermal energy's potential contributions to sustainable development, highlighting its economic viability, environmental benefits, technological challenges, and policy implications. By understanding these aspects, stakeholders can better appreciate the role of geothermal energy in the broader context of achieving energy security, reducing greenhouse gas emissions, and fostering global energy resilience in the face of climate change.
