“…As it was mentioned in the SO and ST strategies, enterprises need to cooperate with research organizations to enhance DES techniques, so that transmission and production costs might be reduced. Poland currently uses geothermal heating technologies that successfully reduce the production price [73], although the price of it is still higher than the price of coal but much lower than that of biomass, natural gas and oil. In this case, the development of a new technology and an application of the new technology into real life practice are important.…”

“…To enhance the reliability of analysis results, two methods are used and compared in this study. When considering the enablers of an energy system, most academic researchers classify indicators into three categories that are the social, environmental and economic perspectives [73][74][75][76][77][78]. Some researchers however consider a technical category as well [79][80][81].…”

Background: The conflict between the Chinese fossil fuel-based economy and worsening environmental conditions requires further research to be carried out. Due to their clean, highly-efficient and flexible properties, distributed energy systems (DESs) have become a global research focus in the field of energy conservation. China, as the largest coal-fired energy user and highest power consumer in the world, has to conduct further research and apply the DESs to resolve the conflict. This study aims to provide a comprehensive review of DES development in China as well as improvement suggestions for the development of DESs by use of scientific analysis. Methods: The analysis of strengths-weaknesses-opportunities threats (SWOT) was adapted for the analysis of improvement strategies. The directions for how to improve the application of these strategies were selected by the prioritization method of analytic hierarchy processes (AHP) and evaluated by the best-worst method (BWM). The suggestions were provided according to the ranks figured out by AHP and BWM. Five enablers were selected from the respective economic, environmental, technological and social aspects for participating in this analysis. Results: Resulting from the SWOT analysis, capital investment, technology development and regulation completeness are three aspects of strategies summarized as SO strategies, ST strategies, WO strategies and WT strategies. The research perspectives of DESs that are suggested for investment, technology development and regulation completeness are illustrated by AHP and BWM. The results show that the reduction of solid particle emissions, the improvement of generation reliability, the improvement of the production rate, the reduction of production costs, the improvement of on-site safety, the fulfilment of electricity demand, the reduction of noxious gas emissions as well as the improvement of energy efficiency need to be carried out for the sake of environmental protection and quality of DES generation in China.Conclusions: There are high potentials for China to further develop and apply DES approaches. The direction of current development might be set to solve three problematic aspects, which are capital investment, technology development and regulation completeness.

“…Despite this, it seems impossible to replace fossil fuels with geothermal energy, both globally and in the domestic market. The most important argument is the economic unprofitability of carrying out deep boreholes (the 2,000 m barrier is commonly recognised as the limit for positive economic balance) and too low temperature of borehole waters at the outflow (Huculak et al 2015, Bugajski et al 2017.…”

At present, hydro-geothermal resources in which waters in bores are the carrier of heat energy have commercial importance in Poland. Geothermal waters should feature the highest possible temperature in the outflow, low mineral content, high capacity and low deposit depth. Even though geothermal energy is included in renewable sources of energy, complete depletion of the deposit is the largest risk in extracting geothermal waters. This is why these waters should also feature deposit renewability. There are currently several geothermal provinces with beneficial geothermal conditions in Poland, with the area of the Podhale Basin in the Inner Carpathians region being regarded as the most promising. The Podhale deposit also meets all of the above listed conditions. The possibility of using hydrothermal energy in Poland is practically available throughout the country, but operational use of hot groundwater must be profitable for investors. From another point of view, the environmental impact of such investments should be minimized. This paper is concerned with the special variety of temperature of geothermal waters extracted in the area of the Podhale Basin, which is the basic aspect in using deposits of this type.

The aim of the study was to evaluate the potential to satisfy some energy needs of a rural municipality using renewable energy sources. The research was conducted in the territory of the Municipality of Nowa Słupia in Świętokrzyskie Voivodeship, Poland. The novel aspect of this study was to assess current and potential production of energy from renewable sources. The study included consideration of sources of energy such as the sun, water, wind, and biogas of plant origin; and distinguishing actual, potential, and overall renewable energy sources in the period from the time of the study to 2025. The assessment was based on the sum of existing individual sources and also on opportunities revealed in a development trend analysis of these energy sources. Currently, the municipality does not consume energy from renewable energy sources. In view of the potential volume of energy from renewables, the municipality could meet the demands of its residents at 7.6%. The current volume of thermal energy from renewables, it is here estimated that the municipality could meet the demands at the level of 10.3%. In the future, this source could be developed further beyond the present level of 65.8%, which together with energy crop biomass obtained on set-aside land (approximately 70% of available land) would cover 76.1% of the requirements of municipality residents. This article also includes a few more general ideas about sustainable development and energy as suggested by the case study.
