As the global economy grows, so does the demand for energy. Investment in clean energy projects is increasingly important to help meet these growing energy needs. Clean energy projects are also important for environmental reasons and as part of the battle against climate change. Many clean...

В статье рассматриваются вопросы экономики и организации строительства объектов малой энергетики, использующих гидроэнергетические ресурсы малых рек,...

Hazánk kedvező geológiai viszonyainak köszönhetően a geotermikus energia hasznosítására adottak a feltételek. A geotermikus energia felhasználása az 1960-as évektől lendült fel. Az addigi kitermelés kizárólag egészségügyi és gyógyászati célokat szolgált, ezután jelent...

Increasing energy efficiency should be a concern for both the firm managers and any leader at any level, given that energy efficiency significantly reduce production costs. An important aspect of this is the use of renewable energy sources, in different types of activities, depending on the...

This paper presents a dynamic simulation model and a parametric analysis of a solar-geothermal hybrid cogeneration plant based on an Organic Rankine Cycle (ORC) powered by a medium-enthalpy geothermal resource and a Parabolic Trough Collector solar field. The fluid temperature supplying heat to...

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...
