An advantage of the geothermal over other renewables is its non-intermittent character (Richard Wolfson, 2011). Unlike the wind, hydro or solar power the geothermal energy is continuously produced uninterrupted by any weather conditions, which means it can be used at any time of the day, any day of the year. This feature allows for a reliable baseload power provider, especially for the electric grid. The total global geothermal energy amounts to about 42 million megawatts, however only a fraction of it can be utilized (Meyers, 2012). Exploitation of this renewable is limited to areas where geological conditions permit a carrier i.e. water or steam to conduct the heat from the earth core nearer the earth surface. The Earth becomes hotter by about 25°C per kilometer of depth by average. In the geothermal hot spots, the temperature increases 60°C per kilometer of depth, creating optimal conditions for harvesting
