Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials.

"Geo" means "from the earth," and "thermal" means "heat," so this type of energy is found under the earth. The hot lava from a volcano and the hot steam from a geyser both come from underground heat and we can use that same type of heat in our homes.
Here's how it works: about four feet underground, the temperature of the earth stays the same all year long, about 55 degrees.
A geothermal heating system uses pipes buried more than four feet deep in the earth. That is another reason why it's important for adults to call 811 before they dig in their yard so they don't hit buried piping.
The system pumps a liquid through the pipes to absorb the heat and brings it back indoors. A device called a "heat exchanger" takes the heat from the liquid and uses it to heat the air inside the home.
