- W2548345312 abstract "Zusammenfassung: Geothermale Energie, eine Alternative fur Rumanien. Geothermale Energie kann mit Hilfe von Bohrungen aufgefangen werden, falls dabei heises Wasser oder Dampf unter Druck in die hoheren Schichten der Erdkruste gelangen. Geothermale Kraftwerke nutzen Dampf mit hoher Temperatur und Druck, welchen sie in elektrische und geothermale Energie umwandeln. Die Nutzung geothermaler Energie reduziert die Suche nach fossilen Brennstoffen, sie ist erneuerbar und hat geringe Auswirkungen auf die umgebende Umwelt. Schlusselbegriffe: geothermale Energie, Bohrung, erneuerbare Energie, geothermale Kraftwerke Connected to a large extent with volcanic activity, geothermal energy can be attracted in conditions when hot water or fumes under pressure reach the artificial stratums of terrestrial crust. The energy emitted by volcanic eruptions reaches inconceivable amounts so that the power of Perbuatan volcano from Krakatua Island from 1883 was calculated to 5000 megatons. In Kamceatka peninsula, the Bezimianii volcano, which erupted between the years 1955-1956 threw on surface materials which in total were 2.4 millions tons and the emitted energy was evaluated to 40000 milliards KWh. What a volume of power resources would have been saved through the catching of this enormous energy is easy to imagine. In the same time, the geysers and some thermal waters can be catched in order to be used in electrical energy production and for the warming of different spaces or water. Geothermal energy is already used in certain countries as Russian Federation, Hungary, Iceland, Italy, New Zeeland, Japan, Romania etc. Geothermal power plants use fumes at high temperature and pressure which are found in terrestrial crust and they are brought to surface through drilling. These fumes have a temperature as high as 230 0 C and a pressure of 5 to 30 atmosphere. The most important power plant of this type was built to Larderello (Toscana in Italy), this having a power installed of 370 MW and an annual production of 2 milliards KWh. There were also built power plants of small and medium capacity which are put in function by the energy emitted by hot fumes and water extracted through drilling, or which appear at surface in some countries as SUA, where they ensure an annual production of 615 millions KWh especially in stratums from mountains from West (Geyser power plant) and with big perspectives in California where, starting with 1960 were advantaged the geysers from there in power plants with a power installed of 400 mw; in the New Zeeland at Wairakei there is a power plant since 1958 with a power installed of 290 MW. In Iceland where the geothermal energy ensures some home necessities it also supports facilitates for the production of cultures in green houses. In Kamceatka peninsula from Russian Federation and in Budapest, in Hungary, but also in Romania, it is used geothermal energy for power plants." @default.
