Public Geothermal Companies
A List of Geothermal Stocks
Geothermal power is energy that is generated by heat stored in the earth, or the collection of absorbed heat derived from underground, the atmosphere, and oceans. The resources for geothermal energy fall in between shallow ground and molten rock miles below the Earth's surface.
There are many advantages of geothermal energy, including low emissions, no purchase of fuel, power plants unaffected by weather conditions, and a sustainable source of energy due to comparatively small heat small extraction and natural replenishment.
Over the past few years, public geothermal companies have begun to spring up due to the recognition of geothermal energy as a valuable source of energy.
