Geothermal energy
— Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhousegas (GHG) emissions. Geothermal energy is the thermal energy stored in the underground, including any contained fluid, which is available for extraction and conversion into energy products. Electricity generation, which nowadays produces 73.7TWh (1...
متن کاملFractal Characterization of Subsurface Fracture Network for Geothermal Energy Extraction System
As a new modeling procedure of geothermal energy extraction systems, the authors present two dimensional and three dimensional modeling techniques of subsurface fracture network, based on fractal geometry. Fluid flow in fractured rock occurs primarily through a connected network of discrete fractures. The fracture network approach, therefore, seeks to model fluid flow and heat transfer through ...
متن کاملGeothermal Energy in Iceland
Due to Iceland’s location on the Mid-Atlantic ridge, the island is provided with a great amount of geothermal energy. Hence, Iceland is well on the way to becoming completely independent of fossil fuels. Whereas high-temperature areas are mainly used for electricity generation, the more frequent low-temperature areas are utilized for direct application like space heating, bathing and greenhouse...
متن کاملGeothermal Energy in Finland
The use of geothermal energy in Finland is restricted to the utilization of ground heat with heat pumps. This is due to the geological conditions as Finland is a part of the Fennoscandian (or Baltic) Shield. The bedrock is Precambrian covered with a thin (<5 m) cover of Quaternary sediments. Topography is subdued and does not easily produce advective re-distribution of geothermal heat by ground...
متن کاملGeothermal Energy Use in Europe
Europe is the world leader in geothermal direct use. Geothermal is used in 32 European countries mainly for space heating, bathing and balneotherapy, than for heating greenhouses, aquaculture, and industrial use. In a number of countries the development is based on waters exploited from deep wells. Some countries have been dynamically developing shallow geothermal based on heat pumps. Power gen...
