See how we can generate clean, renewable energy from hot water sources deep beneath the Earth''s surface. The video highlights the basic principles at work in geothermal energy production and illustrates three different ways the earth''s heat
The slow decay of radioactive particles in the earth''s core, a process that happens in all rocks, produces geothermal energy. The earth has four major parts, or layers: An outer core of hot molten rock called magma that is about 1,500 miles thick.
Geothermal energy is heat that is generated within Earth. ( Geo means "earth," and thermal means "heat" in Greek.) It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below Earth''s crust, or surface, is the hottest part of our planet: the core.
Geothermal energy is thermal energy extracted from the Earth''s crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia.

5 · Geothermal energy is produced from reservoirs of hot water below the Earth''s surface. It is a renewable energy with some benefits over solar and wind. Many questions surrounding geothermal energy are answered: how does it work?
This report shows how advanced geothermal technology could increase the United States'' geothermal energy production to 90 gigawatts or more by 2050, a twentyfold increase.
Geothermal energy is derived from the natural heat of the earth. 1 It exists in both high enthalpy (volcanoes, geysers) and low enthalpy forms (heat stored in rocks in the Earth''s crust). Nearly all heating and cooling applications utilize low enthalpy heat. 2; Geothermal energy has two primary applications: heating/cooling and electricity
Geothermal energy is heat energy within Earth that can be captured and harnessed for electrical power generation, space heating and cooling, and various direct uses.
Learn how geothermal power plants use dry steam, flash steam or binary steam from reservoirs in the earth to produce electricity.
