USA, Washington: The Potential for geothermal Energy in the North West

Earth Day 2016: Moving Toward Green Energy ( Washington State Geology News)

What is Geothermal Energy?

Geothermal energy is thermal energy generated and stored in the earth. When most people think of geothermal they think of hot springs, fumaroles, and geysers. These are surface features that are linked (through faults and fractures) to the subsurface hydrothermal reservoir. Geothermal energy can be harnessed by drilling into hydrothermal reservoirs and extracting the hot fluids and/or steam.

Check out this Geothermal 101 video or this one on geothermal heat pumps to learn more.

Geologists and engineers can tap deep into a hydrothermal reservoirs to generate electricity, or use the shallow heat beneath the surface to heat and cool homes throughgeothermal heat pumps.
