Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity.
How Is Geothermal Energy Harnessed?
Geothermal energy is an abundant, renewable and clean source of energy that is derived from the Earth’s internal heat. It is a naturally occurring thermal energy that is generated by the Earth’s internal heat and is harnessed as a form of renewable energy. Geothermal energy has been used for centuries to provide warmth, hot water, and electricity.
The most common way geothermal energy is harnessed is through geothermal power plants. Geothermal power plants use the Earth’s natural heat energy to generate electricity. Heat from the Earth’s interior is collected by drilling deep wells to depths where temperatures can exceed 700°F. The hot water and steam from these wells are then piped to the surface, where it is used to spin turbines that generate electricity.
Geothermal energy can also be harnessed directly from hot springs, hot rocks or geysers. Hot springs are naturally occurring sources of hot water that have been heated by the Earth’s internal heat. This hot water can be used to generate electricity or to heat homes and buildings. Hot rocks are heated rocks beneath the Earth’s surface that are heated by the Earth’s internal heat. The heat from these rocks can be extracted and used to generate electricity. Geysers are hot springs that periodically erupt hot water and steam
