The use of geothermal energy is limited to direct utilization in Tunisia, because of the low enthalpy resources. The resources are localized mainly in the southern part of the country in the regions of Gabes, Kebili and Tozeur and utilized mostly for agricultural purposes (irrigation of oases, greenhouses). The government's policy in the beginning of the 1980's was oriented to the development of the oasis' sector and the main aim was to supply oases with geothermal water for irrigation. Therefore, in the Kebili area, about 35 boreholes are operating mostly for irrigation of 15,500 ha of oases after cooling the water in atmospheric towers. Fifteen years ago (1986) the State started using geothermal energy for greenhouse farming, by planting an area of one ha. The results of this experiment were very encouraging and thus, the areas today have increased to 40 ha.
