This heat heats ground water to form hydrothermal resources (naturally occurring hot water/steam in fissures [diagram: C/D]). Wells (diagram: F) are drilled to tap fissures for hot water, and the steam can be used to generate electricity, as described in the next section. Hot water may also emerge on the surface as hot springs or geysers (diagram: E). Utilizing geothermal energy not only contributes to our energy supp....
