Review Questions

• How does reservoir pressure influence the utilization of geothermal energy?
  • Reservoir pressure plays a crucial role in determining the temperature and flow rate of geothermal fluids. Higher pressure generally allows for higher temperatures at a given depth, enhancing the efficiency of energy extraction. This means that effective utilization strategies must account for pressure variations to optimize both heat production and electrical generation from geothermal resources.
• Discuss the impact of temperature on different methods of geothermal energy utilization.
  • Temperature directly affects the choice of geothermal energy utilization methods. For instance, low-temperature resources are often best suited for direct use applications like heating buildings or greenhouses, while high-temperature resources are typically used for electricity generation in power plants. Understanding this relationship helps in designing systems that maximize the potential of available geothermal resources based on their temperature profiles.
• Evaluate the long-term sustainability challenges associated with the utilization of geothermal resources and propose strategies to address them.
  • The long-term sustainability of geothermal resource utilization is challenged by factors like reservoir depletion and environmental impacts such as induced seismicity. To address these challenges, strategies should include rigorous monitoring of reservoir conditions, implementing advanced technologies like Enhanced Geothermal Systems (EGS) for better resource management, and promoting policies that encourage sustainable practices. By balancing extraction rates with natural replenishment and investing in research for improved techniques, we can ensure that geothermal resources remain viable for future generations.
