“…Piasecka et al [20], however, has proposed a method of assessing the destructiveness of costs appearing in the wind power plant lifecycle in four categories: de-ergonomicity, defunctionality, environmental performance breakdown, and biosphere conservation breakdown, showing that the greatest negative impact of both onshore and offshore wind power plants occur in the area of de-ergonomicity. Much research has examined the benefits resulting from the operation of wind power plants, i.e., electricity production, or the ways to both predict or increase wind farm productivity [21][22][23][24][25][26]. Economic matters relating to the operation of wind power plants have also been addressed as one important aspect thereof [27][28][29][30].The significant potential of construction materials such as steel, plastics, and concrete are used to produce wind power plant components.…”

The production of energy in wind power plants is regarded as ecologically clean because there being no direct emissions of harmful substances during the conversion of wind energy into electricity. The production and operation of wind power plant components make use of the significant potential of materials such as steel, plastics, concrete, oils, and greases. Energy is also used, which is a source of potential negative environmental impacts. Servicing a wind farm power plant during its operational years, which lasts most often 25 years, followed by its disassembly, involves energy expenditures as well as the recovery of post-construction material potential. There is little research in the world literature on models and methodologies addressing analyses of the environmental and energy aspects of wind turbine modernization, whether in reference to turbines within their respective lifecycles or to those which have already completed them. The paper presents an attempt to solve the problems of wind turbine modernization in terms of balancing energy and material potentials. The aim of sustainable modernization is to overhaul: assemblies, components, and elements of wind power plants to extend selected phases as well as the lifecycle thereof while maintaining a high quality of power and energy; high energy, environmental, and economic efficiency; and low harmfulness to operators, operational functions, the environment, and other technical systems. The aim of the study is to develop a methodology to assess the efficiency of energy and environmental costs incurred during the 25-year lifecycle of a 2 MW wind power plant and of the very same power plant undergoing sustainable modernization to extend its lifecycle to 50 years. The analytical and research procedure conducted is a new model and methodological approach, one which is a valuable source of data for the sustainable lifecycle management of wind power plants in an economy focused on process efficiency and the sustainability of energy and material resources.

“…Also, in this study, exergy, exergo-economic, exergo-environmental, and exergy accounting analyzes have not been used to find the most suitable locations for renewable hydrogen production, and there is still a good research field in this area. Therefore, the issues such as a new systematic decision support framework based on solar extended exergy accounting performance to prioritize photovoltaic sites, 65 performance assessment of a wind power plant using standard exergy and extended exergy accounting (EEA) approaches, 66 and Spatio-temporal solar exergoeconomic and exergoenvironmental maps for photovoltaic systems 67 are suggested in the future research. On the other hand, the development of hydrogen production projects using technical and economic assessments in other developing and underdeveloped countries is also suggested for future research.…”

Due to population growth and industrial development in the Kingdom of Saudi Arabia (KSA), energy demand has increased. On the other hand, the consumption of fossil fuels has led to adverse environmental effects. This has led to government investment in clean energy. In many sectors of this country, there is good potential for using wind energy. Production of hydrogen from wind farms is a method for reducing energy swings, and it may also be utilized as a fuel in Saudi Arabia's businesses. As a result, the purpose of this research is to discover the best location for hydrogen generation from wind energy utilizing Multi-Criteria Decision-Making (MCDM) techniques. The criteria were weighted using the Step-wise Weight Assessment Ratio Analysis (SWARA) approach. The most important criteria were determined to be "average wind speed," "number of refineries in the region," and "wind power density" with values of 0.2780, 0.2570, and 0.1570, sequentially. Then, the Weighted Aggregated Sum Product Assessment (WASPAS) approach was used to rank the locations. Finally, three other techniques, namely the Evaluation based on Distance from Average Solution (EDAS), the COmplex PRoportional ASsessment (COPRAS), and the Weighted Sum Model (WSM) were used to validate the results. Saudi Arabia's Eastern Province was recognized as the best position for hydrogen expansion in the country. The Eastern Province, with a rated capacity of 900 kW, was anticipated to produce 1863 MWh of energy and 30.16 tons of hydrogen every year.

Evaluation of the Water–Energy–Land Nexus (WELN) Using Exergy-Based Indicators: The Chilean Electricity System Case

The competition and interlinkages between energy, water, and land resources are increasing globally and are exacerbated by climate change and a rapid increase in the world population. The nexus concept has emerged for a comprehensive understanding related to the management and efficiency of resource use. This paper assesses water-energy-land nexus (WELN) efficiency through integration of the principles of Life Cycle Assessment (LCA) and exergy analysis, using the Chilean energy sector (CES) as a study case. The cumulative exergy consumption (CExC) and cumulative degree of perfection (CDP) are used as indicators for WELN efficiency. The results show the production of 1 MWh of electricity required 17.3 GJ ex , with the energy component of WELN (fossil and renewable energy sources) being the main contributor (99%). Furthermore, the renewable energy technologies depicted higher CDP of the water-energy-land nexus due to lower CExC and higher technology efficiency concerning non-renewables. The water and land resources contributed slightly to total exergy flow due to low quality in comparison with the energy component. Nevertheless, water availability and competition for land occupation constitute important issues for reducing environmental pressures and local conflicts. This study demonstrated the feasibility of exergy analysis for the evaluation of WELN efficiency through a single indicator, which could facilitate the comparison and integration with different processes and multi-scales.Energies 2020, 13, 42 2 of 20The nexus concept is an systematic approach for improvement of resource management, which can reach high degrees of complexity depending on scales and processes [9]. Consequently, different qualitative and quantitative methods for conceptualizing the relationship between natural resources have been proposed. Ringler et al.[10] developed a comprehensive qualitative framework for assessing the water, energy, land and food nexus (WELF), highlighting the relevance of land in the nexus. Nevertheless, the authors did not provide methods for the WELN-nexus evaluation. Siciliano et al. [11] have recently reported on the effect of large scale farm investment in the European Union on the water-energy-land-food (WELF) nexus, using indicators related to resource availability, scarcity and access. Although the authors describe several interlinkages between the resources, the quantitative evaluation of the nexus is not clearly highlighted. Karabulut et al. [12] studied the ecosystem-water-food-land-energy (WFLE) nexus by considering the ecosystem as the main issue within this nexus. The authors highlightsthe relationship between interventions and environmental impacts. In this case, the nexus evaluation is qualitative, and the matrix proposed can be adapted to different scales to investigate the trade-offs, synergies and antagonisms.Different approaches have been used to quantitatively evaluate the WELN. Silalertruska and Gheewala [13] carried out the evaluation of the WELN of sugarcane production in Thailand, using wat...
