Review Questions

• How does high-temperature resource utilization impact the efficiency of geothermal power generation?
  • High-temperature resource utilization directly affects the efficiency of geothermal power generation by enabling higher thermal energy conversion rates. When extracting steam or hot water from reservoirs above 150°C, power plants can achieve greater electricity output compared to lower temperature systems. This efficiency is crucial for making geothermal energy a competitive alternative to fossil fuels, leading to increased investments in high-temperature projects.
• Discuss the role of Enhanced Geothermal Systems (EGS) in expanding high-temperature resource utilization capabilities.
  • Enhanced Geothermal Systems (EGS) play a pivotal role in expanding high-temperature resource utilization by allowing access to previously untapped geothermal resources. By injecting water into hot rock formations to create steam, EGS enhances the productivity of these systems. This technology not only increases the potential for electricity generation in areas with lower natural geothermal activity but also diversifies the geographical locations where high-temperature resources can be effectively utilized.
• Evaluate the environmental implications of high-temperature resource utilization in contrast to traditional energy sources.
  • High-temperature resource utilization offers significant environmental advantages over traditional fossil fuel-based energy sources. Geothermal energy is a renewable resource that produces minimal greenhouse gas emissions during operation. Additionally, when managed properly, it has a smaller land footprint and less impact on ecosystems compared to coal or natural gas extraction processes. As society shifts towards sustainable energy practices, the efficient use of high-temperature resources can contribute to reducing reliance on fossil fuels and mitigating climate change effects.
