The United States’ geothermal energy sector has gradually expanded in recent years, as states look to diversify their energy mix. While several renewable energy sectors have struggled to stay afloat under the Trump administration, the government has continued to show support for geothermal energy development. Further, innovations in enhanced geothermal technologies are expected to support greater sectoral expansion in the coming years. Geothermal energy is generated by drilling into underground heat pockets in the Earth’s surface to access heat. The Earth’s core has a temperature of around 5,200°C, while rock and water in the Earth’s crust can reach temperatures of around 370°C. Energy operators typically drill reservoirs just a few miles underground to access thermal energy in the rocks, as well as warm water deposits. The heat is used to drive turbines to achieve carbon-free electricity production . California is home to 53 of the 99 U.S.…
