Geothermal Basics
Geothermal Energy
Geothermal energy is heat energy from the earth—geo (earth) + thermal (heat).
Geothermal resources are reservoirs of hot water that exist or are human-made at varying temperatures and depths below the earth's surface.
Wells ranging from a few feet to several miles deep can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including:
Electricity Generation
Deep underground, the presence of hot rocks, fluid, and permeability (the ability for that fluid to move among the rocks) offer conditions from which electricity can be generated.
Using natural or human-made permeability and fractures, the fluid flows through the hot rocks, absorbing heat from the rocks that can be drawn up through wells to Earth’s surface. That heat energy is then converted to steam, which drives turbines that produce electricity.
