Geothermal energy harnesses heat stored beneath the Earth’s surface to generate power. This renewable energy source exploits the Earth’s internal heat, often derived from magma, hot water reservoirs, or high-temperature rocks. Geothermal power plants extract this heat through wells or directly from the Earth, converting it into electricity. There are three main types of geothermal power plants: dry steam, flash steam, and binary cycle. Geothermal energy is sustainable, produces minimal greenhouse gas emissions, and provides a reliable and continuous source of power. It is utilized for electricity generation, heating, and cooling applications, contributing to a more environmentally friendly and diversified energy portfolio.
