Geothermal Situation in the Area of Greek Islands and Coastal Area

Abstract

Geothermal energy is a term that refers to thermal water or steam, which is concentrated at accessible depths (less than 3km) and can be economically exploited. This kind of energy is the sole renewable source not directly or indirectly connected to solar energy. It is a reliable and always available source: day and night throughout the year. Provided that it is properly implemented, geothermal energy is a sustainable and benign to the environment resource. Since the transfer of geothermal energy far from its source for long distances is not very common or advantageous, its exploitation for local development activities or for the energy self-dependence of isolated areas (e.g. islands) is particularly favorable.
