Hot dry rocks: An inexhaustible and renewable source of energy

Geological, methodological, and economic aspects of the production and utilization of petrother mal resources (heat of “dry” rocks) for electric energy production and heat supply are considered. Possibility of the utilization of natural fracture zones or artificial fissure zones, which are created by hydraulic fracturing of underground rock massifs, is noted. Application of new tools for drilling deep wells makes the petrochemical energy competitive relative to both other types of renewable resources and traditional organic fuel.
