In Croatia there is an urgent need to improve energy balance with more efficient methods of energy resources exploitation. There are approximately 3,000 wells drilled on oil, gas/condensate and geothermal reservoirs, of which only 50 were primarily drilled for purpose of geothermal exploitation....

At the beginning of the 1980s the installed geothermal electric capacity in the world was 1960 MW, rising to 3698.5 MW in 1985, and 5835.5 MW in 1990. At the beginning of 1993 the installed capacity had reached 5915 MW, an increase of 202% with respect to 1980. The percentage increase in...

In the absence of any likely international law in the near future to impose comprehensive obligations on nations to take action to promote renewable energy or energy conservation, such action will be required at national level. This paper proposes a generic legislative framework for the control...

In the paper renewable energy resources in Poland were analysed and estimated. The following sources were taken into consideration: solar radiation, biomass including biogas, liquid and solid biofuels, geothermal, hydro and wind energy. Some technologies suitable for application in Polish...

Afyon geothermal district heating system (AFJET) provides heating to 4519 residences, covering an area of 513,683m2. Due to limitations in reinjection capacity, geothermal waters are released to the Akarcay Stream, detrimentally affecting the environment. Optimum heating load of the system was...

Increasing activities of geothermal development especially in the last three years result in a geothermal boom in Turkey. Not only the addition of new sites, but also updating the data of existing ones increased the currently identified capacity significantly. With the discoveries of 13 new...

The ability to discover and utilize a reliable source of renewable energy is vital in order to reduce the effects of global warming and to decrease and/or eliminate reliance on fossil fuel. Recently, countries around the world have been recognizing the immediate need to tackle the current energy...
