As its name implies, geothermal energy is power that comes from the natural heat of the earth. The molten nickel core of the earth is like a giant blast furnace raging at temperatures up to 9000 degrees Fahrenheit.

That heated core is continuously pressing against the earth’s rock mantle, both heating the rock and escaping through fissures in the form of lava.

What begins as extreme high temperature and pressure that is relatively close to the earth’s surface can be harnessed and utilized to provide clean energy in large-scale utility applications or smaller-scale lower-heat applications.

Geothermal energy is considered environmentally friendly because it produces very low greenhouse gas emissions compared to fossil fuels. However, its availability is geographically limited to regions with significant geothermal resources, such as Iceland, the Philippines, the United States (particularly in the western states), and parts of East Africa.

Advances in technology, including Enhanced Geothermal Systems (EGS), are expanding the potential for geothermal energy utilization in a broader range of locations.

Geothermal power sources are more abundant that all currently known energy sources, does not require energy to produce, and does not pollute the environment.
