Geothermal - Statistics & Facts

Published by T. Wang, Jan 31, 2019
Geothermal energy has been used for thousands of years for cooking and heating purposes. Modern technology has allowed us to harness it more effectively and its popularity has gradually grown in regions around the world, represented by increasing numbers of geothermal power installations. Geothermal energy is derived from the energy found within the Earth’s crust. Heat is produced continuously by magma, which itself is heated by the natural decay of radioactive materials such as uranium and potassium. It is estimated that the amount of heat stored within 10,000 meters of the Earth’s surface contains about 50,000 times more energy than all of the oil and gas resources worldwide.

Geothermal energy may be most efficient in areas with high underground temperatures – “hot spots” with active or geologically young volcanoes. For example, the Pacific Rim or the Ring of Fire, located along Alaska, California, and Oregon, has many hot spots. The United States has the largest installed geothermal capacity in the world. Nevada holds the majority of the country’s geothermal capacity and is continuing to develop new projects.

Geothermal power potential varies across the world based on the seismic activity that occurs under the earth’s surface and its geology. Regions with milder heat can be also be used, primarily for direct heating purposes. This heat energy is normally extracted from shallower depths. Dry rock formations between four to ten kilometers below the surface can also provide vast amounts of heat energy. There are various technologies that have been developed to extract geothermal energy.
