Enhanced geothermal system

An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction.^[1] However, most geothermal energy within reach of conventional techniques is in dry and impermeable rock.^[2] EGS technologies expand the availability of geothermal resources through stimulation methods, such as 'hydraulic stimulation'.
