Geothermal Energy Concepts and Challenges

Geothermal energy, a renewable resource beneath the Earth's surface, has the potential to meet global energy needs for millions of years. Despite its long history, it currently contributes minimally to the energy mix due to high costs and technical challenges. However, advancements in drilling technology and increased interest from oil and gas companies are driving a resurgence. Startups are innovating with Enhanced and Advanced Geothermal Systems, aiming to make geothermal energy more accessible and cost-effective. The collaboration between traditional energy sectors and geothermal startups is crucial for scaling this sustainable energy source.
