What is Geothermal Energy?
Geothermal energy is generated by tapping into the Earth’s internal heat, which is produced by the decay of radioactive elements in the Earth’s core. This heat is then used to produce steam, which drives a turbine to generate electricity. The process is similar to traditional fossil-fuel power plants, but with a significant difference: geothermal energy is a renewable resource that’s available 24/7, without the need for fuel.
