United States of America — Energy ProfileGeothermal power generation harnesses the Earth's internal heat to produce electricity. This renewable energy source exploits the thermal energy stored beneath the Earth's crust, which can be accessed through geothermal power plants. These plants typically utilize steam or hot water from geothermal reservoirs to drive turbines that generate electricity. The process begins by drilling wells into geothermal reservoirs, often located in tectonically active regions, where the temperature gradient is favorable for energy extraction. The steam or hot water extracted is then channeled to turbines, converting thermal energy into mechanical energy, which is subsequently transformed into electrical energy by generators.
