"The amount of heat that flows annually from the Earth into the atmosphere is enormous-equivalent to ten times the annual energy consumption of the United States and more than that needed to power all nations of the world, if it could be fully harnessed." U.S. Geological Survey

Geothermal energy is produced from the heat constantly radiating from the Earth's interior. We've been enjoying this energy for centuries at hot springs and geysers. Modern technology allows us to drill deep into the earth's surface and harness the power of geothermal energy. Geothermal fluids at high temperatures can be utilized as high-pressure steam to drive turbine generators to produce electricity.

Geothermal energy is a clean, renewable source of power. Emissions from geothermal plants are low and sources of geothermal fluid can be replenished by pumping treated wastewater back into the reservoir.
