In a national appeal, the Egyptian Supreme Energy Council announced the state's plan, which aims to get the contribution of new and renewable energy by about 20% in electricity production of the total demand by year 2020, pointing to initiate locate and prepare feasibility studies. Among the promising renewable energy are the geothermal sources. The geological structure and tectonic setting of Egypt suggests that it might contain an immense distribution of geothermal resources, particularly along its eastern edge. The most encouraging areas for geothermal development are located close to the Red Sea and the Gulf of Suez, which are associated with the East African Rift System. This paper reviews the state-of-the-art geothermal resources in Egypt with an emphasis on the current investigation utilizing aeromagnetic data. Aeromagnetic data of whole Egypt was used to estimate the Curie point depth (CPD), heat flow and geothermal gradient and compered with seismic activity. The CPDs range from 8.6 to 35.7 km, the derived geothermal gradients vary from 16.3 to 67.4°C/km, and the heat flow values range from 47.1 to 195.5 mW/m2. Most of the earthquakes that originated in areas with CPDs of less than 25 km are considered promising regions for geothermal exploration, especially in the Gulf of Suez. The results of the current study may guide governmental and private sectors interested in the geothermal energy industry to select the most appropriate geothermal power plant sites in Egypt.
