2. Geothermal Energy  Geothermal energy is the thermal energy that is generated and stored inside earth.  Heat comes from the earth’s mantle and it’s tapped into in order to heat buildings and generate electricity.  Heat can come up to the earth’s surface in hot springs and geysers.

3. History of Geothermal Energy  There is archaeological evidence that humans first used geothermal resources in North America since the settlement of Paleo-Indians 10,000 years ago.  People have used geothermal heat for centuries and the ability for earth to produce heat has always been around.  The first geothermal energy facility was built in Italy in 1904.

4. Where it’s found  Geothermal reservoirs are deep underground and are usually found along plate boundaries where volcanoes and earthquakes are concentrated.  In the U.S, most geothermal power plants are located in the western states and Hawaii.  California is the largest known dry steam field in the the world. “The Geysers” reservoir
