Some of these springs may be used to produce electricity for the villages and towns near to them. If the waters are very hot, then flash steam geothermal plants can be set up. By drilling down to where it is much hotter than at the surface, the hot water could be used to produce steam, which in turn can turn a turbine, which turns a generator, which produces electricity.
If the ground is not so hot, then a binary geothermal system could be set up. The less hot water is taken up from deep in the ground and its warmth is used to boil something like methanol or ammonia, which boils at a lower temperature than water. The ammonia or methanol steam then turns the turbine, which turns the generator, which produces electricity.
If producing electricity near warm and hot springs seems odd to some, it does happen in some areas of the world where the tourism places produce electricity from the same temperatures that keep the tourists coming for mineral, warm and hot baths for health and relaxation.
