Geothermal power generation is the method of extracting high-temperature steam and hot water (about 200 to 350°C) from a geothermal reservoir under the ground of a volcanic zone and then generating electric power with a turbine.

In 2009, Krewitt et al. estimated the technically available amount of geothermal energy to be 12,500 TWh/y, which is equal to 62% of global power consumption in 2008.1 Geothermal resources exist mainly in volcano-rich countries, and the amount of resources is estimated to be 30,000 MW in the U.S., 27,790 MW in Indonesia, 23,470 MW in Japan, 6,000 MW in the Philippines, and 6,000 MW in Mexico . In 2010, 2 to 25% of resources have been utilized. From now on, we need to reduce the cost for plant operation, compete with hot-spring facilities, coordinate with the regulations for national parks, and manage the risk of eruption among other things.

There is no geothermal energy session this year at ICEF, but the European Geothermal Congress, the largest geothermal event in Europe will be held this year on September 19-23 in Strasbourg, France. It is held every 3 years and it attracts everyone working in the sector both in and outside Europe. Follow the link below for details. http://europeangeothermalcongress.eu/
