Heat from the Earth

Geothermal Energy is heat (thermal) derived from the earth (geo). It is the thermal energy contained in the rock and fluid (that fills the fractures and pores within the rock) in the earth's crust.

Geothermal energy is tapped, and utilized to generate electricity.  Because the amount of heat in the earth is so great, and the amount of heat used to generate electricity is a small fraction of that heat, geothermal energy is considered a renewable energy resource. 



The Role of the Forest Service

The Forest Service, in conjunction with the Bureau of Land Management, provides opportunities for the exploration, development, and production of geothermal resources on National Forest System lands.
