Turkey is rich in geothermal energy resources. It ranks seventh in the world for this type of energy resource and among the top five for geothermal heat and thermal spring applications (electricity generation, heating and cooling homes and greenhouses, drying, thermal tourism, balneological use, mineral extraction, agricultural and aquaculture applications, etc.). Interest in this energy field is rising due to government support for renewables. An overview of geothermal energy in Turkey is presented and its potential is evaluated. The study aims to contribute to the future developments of this energy technology in Turkey, with some barriers also considered.

This law declares Costa Rica's interest in the exploration of geothermal energy resources. It states that all activities concerning geothermal energy are the sole responisbility of the Instituto Costarricense de Electricidad (ICE). Under this law, ICE is authorized to acquire all land required for research, exploration, exploitation and protection of geothermal resources, applying the provisions of Act No 2292 of November 20, 1958.

"Compilation of investigations of low-temperature ground-source geothermal and high-temperature hydrothermal systems. Contributions include studies on the feasibility of integrating geological modeling with system design, extraction of low-temperature geothermal energy in underground coal mines, ground-source heat pump systems, models that couple heat transfer with groundwater flow and/or stratigraphy, and enhanced geothermal systems"--

Geothermal energy is heat generated within the Earth's crust as a result of the planet's formation and the radioactive decay of materials. Thermal energy is stored in rocks and fluids in the centre of the Earth.

How wonderful:At United Downs, a stone's throw from many of the old mines, a pioneering project run by Geothermal Engineering is drawing heat from granite rocks that lie more than three miles below the surface.It does this by pumping out water warmed to 200 degrees celsius to power a heat exchanger, before being pumped back down again to a shallower well.It's a known technology, it works, it is at least possible for it to be economic, so why not? Well, of course, this being Britain we do have a problem:However, the UK currently lacks a specific regulatory regime for geothermal, according to a House of Commons Library report,That's one of those things that is terribly easy to provide. Just print the fracking regs with "geothermal" copy pasted in where necessary. The similarity - drilling holes which might cause earthquakes, more importantly the reinjection of wastewater which causes earthquakes - is obvious enough that they can and should be both governed by the same rules. So, what's to stop us? Except the clear point that if geothermal were to be restricted by the same rules as fracking then geothermal would not be possible. Therefore geothermal will gain different rules - and the hypocrisy of the fracking rules will be revealed. Not that they've exactly been hidden, but made even more clear perhaps. Nothing like the clear rule of law, is there, and this is nothing like it.

This legislation establishes the administrative, legal, and technical procedures regarding the exploration and exploitation of geothermal energy.

Germany uses its low enthalpy hydrothermal resources predominantly for balneological applications, space and district heating, but also for power production. The German Federal government supports the development of geothermal energy in terms of project funding, market incentives and credit offers, as well as a feed-in tariff for geothermal electricity. Although new projects for district heating take on average six years, geothermal energy utilisation is growing rapidly, especially in southern Germany. From 2003 to 2013, the annual production of geothermal district heating stations increased from 60 GWh to 530 GWh. In the same time, the annual power production increased from 0 GWh to 36 GWh. Currently, almost 200 geothermal facilities are in operation or under construction in Germany. A feasibility study including detailed geological site assessment is still essential when planning a new geothermal facility. As part of this assessment, a lot of geological data, hydraulic data, and subsurface temperatures can be retrieved from the geothermal information system GeotIS, which can be accessed online [1].
