Geothermal is, literally, earth-heat<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tFrom the Greek geo \u2013 therme, heat is a form of energy \u2014 and geothermal becomes an energy resource when we can use this heat to our advantage. Most of the Earth’s heat lies deep inside the planet, beyond the reach of technology. At relatively shallow depths, depending on the temperature, the heat may be economically extracted and used \u2014 and the shallow Earth itself may serve as a heat reservoir.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Potential still to be unexploited<\/span><\/h2>\r\n

The Moroccan subsoil holds geothermal energy potential still unexploited \u2014 especially in the northeast, where the estimated installed capacity is around 5 MWe. Geothermal data from deep oil wells highlights a heat flux increasing northeastward across the eastern Rif, northeastern Morocco, the Alboran Sea, southeastern Spain and northwestern Algeria.<\/p>\r\n

The highest geothermal gradient in Morocco is found in the northeast, reaching up to 50 \u00b0C\/km. Temperature data recorded in a water borehole in the Berkane and Oujda areas revealed an average gradient exceeding 120 \u00b0C\/km at depths greater than 300 m.<\/p>\r\n\r\n
