Geothermal power comes from the heat emitted by the Earth’s core and, on the timescale of humanity at least, can be considered inexhaustible.
Geothermal power, or else the heat emitted by the earth’s core, is utilized since 1904 in order to produce “green” power. The key for the production of the power lies on the geothermal fluids, such as, underground sea or other kind of water tanks. These fluids are heated in high temperatures, often exceeded the 350 C, because of their contact with the already heated, from the lava, which is in the Earth’s core, rocks.
The geothermal fluids extraction, supported by the current advanced technological methods, allows not only the electric power production, but also their use for the sea water desalination, the heating and the refrigeration of the buildings, the greenhouse heating, the fish farming etc. Today, the total capacity of the installed geothermoelectric units surpasses the 9,000 MW, rendering the Geothermy a reliable, available and environmentally friendly alternative source of energy.
The development of Geothermy depends upon specific factors, such as, the depth, the geothermal reservoir characteristics, the composition and the feeding of the geothermal fluid etc. The production of energy from Geothermy is one of the priorities of PPC’s business plan. A great experience has been inherited from PPC as the later conducted Geothermy source research in 1973 and this experience has been an invaluable guide for development in the sector.
