The application of geothermal energy to generate baseload electricity and to provide heat for home and industrial use is growing worldwide. If the current growth were sustained, there would be a global capacity of 200GWe installed by the year 2050. Innovation in drilling, well design, and plant operation are providing new pathways for the geothermal energy sector to be involved. There is also significant scope for oil and gas wells to be repurposed to access geothermal energy. Communities and indigenous people must be central efforts to increase the use of geothermal energy. There are aspirations to grow the use of geothermal energy worldwide—from Africa’s efforts to unlock the potential for further electricity generation and direction to Saudi Arabia’s aspirations to access 1GW to Japan’s wish to explore deep supercritical systems and the drive in the United States to bring enhanced geothermal systems to commercial reality.
