A geothermal power plant harnesses heat from the Earth's interior to generate electricity. This heat originates from the natural decay of radioactive materials and the Earth's molten core. The plant typically uses steam or hot water from underground reservoirs to drive turbines, which then produce electricity. There are different types of geothermal power plants, including dry steam, flash steam, and binary cycle plants. Each type utilizes geothermal resources in unique ways, but all aim to convert thermal energy into electrical energy efficiently. Geothermal energy is considered a renewable resource, as it can provide a consistent and sustainable power supply.
