Geothermal resources consist of thermal energy from the Earth’s interior
stored in both rock and trapped steam or liquid water. As presented in
this chapter, climate change has no major impacts on the effectiveness
of geothermal energy utilization, but its widespread deployment could
play a significant role in mitigating climate change by reducing greenhouse
gas (GHG) emissions as an alternative for capacity addition and/
or replacement of existing base load fossil fuel-fired power and heating
plants.
