Simply put, geothermal energy derived from heat produced by the core of the earth. Geothermal energy is one of the oldest renewable resources used by humans. It has been used since the Ancient Roman times as a heat source. Recently, we have begun to harness that energy as a source of power. Geothermal power plants take the heat from the earth and bring it to the surface to create steam that spins a turbine. We have a constant supply of heat from the earth. The challenge is finding where it is strongest and bringing it to the surface. The Eco Kids will guide us through this process and explain a few different ways that geothermal power plants operate. Find out how experts are working to fine tune the process and make geothermal power plants more affordable and useful across the country.
