Geothermal power

Geothermal energy can be effectively utilized for power generation when the vertical thermal gradient is several times its mean value of about 25 °C km-1, producing near-surface temperatures above 180°C. This condition is achieved at constructive and destructive plate margins, as exemplified by the geothermal power plants in Iceland and the North Island of New Zealand, respectively. Anomalously high geothermal gradients are also present in intra-plate areas where they are frequently associated with granitic plutons. The normal geothermal gradient can be utilized for lower energy power generation, such as for space heating, wherever a thick pile of permeable sediments allows the circulation of fluids to depths of several kilometers. An example of this type is the Paris Basin, where space heating for over 20,000 dwellings is provided by deep fluid circulation.
