Geothermal Energy is the heat that comes from the earth. It's Greek term is "earth heat." This heat is located underneath the earth's crust, from shallow to deep soil.  The temperature at the crust is 5500°C, for every 100 m the temperature rises 3°C.

​

This heat can be created by underground hot water. Volcanoes, hot springs, and geysers help to heat up the water. The energy that is produced by this can be extracted by the process of dry steam, flash steam, and binary power plant.

​

Geothermal energy be used almost everywhere you can think of, except for big cities. Have to take in consideration the type of soil and rock before the energy is extracted. The type of soil and rock affects the amount of heat produced. Other considerations to think about are: if the water is even suitable for use, and the layout of the land. The first plant was named Larderello made in Italy and is in use as of today. The US has 40 plants and plan to make more plants to reduce it's carbon footprint. Iceland use geothermal energy that saves themselves up to 30% of electricity.
