Geothermal power plants harness the Earth's natural heat to generate electricity. They tap into steam or hot water found deep underground, which is produced by the Earth's internal heat. This steam is brought to the surface and used to turn turbines, generating electricity in a clean and sustainable way. These plants are often located near tectonic plate boundaries, where geothermal energy is more accessible. By using renewable energy from the Earth, geothermal power plants help reduce reliance on fossil fuels and lower greenhouse gas emissions, making them an important part of the transition to a more sustainable energy future.
