“…The AHP, introduced by Saaty [50,63], has been widely utilized by researchers across various fields to address the complexity of numerous problems. Several studies have employed the AHP method to develop frameworks for prioritizing alternatives in solar [7,23,33] and flood risk assessment [36,[64][65][66][67]. In the AHP framework, the primary objective, representing the most suitable option, is positioned at the top of the hierarchy (see Figure A1).…”

“…The analytical hierarchy process (AHP), fuzzy analytical hierarchy process (FAHP), network analysis process (ANP), and mathematical models, such as the binary method (Boolean) and fuzzy logic, are some of the MCDA approaches, which are widely employed to facilitate the suitability site identification process for PV power plants. These methodologies enable considering multiple criteria, preferences, and uncertainties, comprehensively evaluating potential sites, and aiding decision making [5,20,33].…”

Sibuyan Island is experiencing a significant increase in electricity demand due to population growth, urbanization, and industrial development. The island plans to use solar energy, recognizing its abundance and renewable nature; thus, this study was conducted to visualize the spatial distribution of solar exploration suitability using a geographic information system (GIS). Various criteria, including climatology, location, geography, meteorology, and disaster susceptibility, were considered in the assessment. Parameters affected by government policies, such as protected areas, proximity to rivers, roads and faults, ancestral domains, and proclaimed watersheds, were also considered. Parameters were weighted, and suitability levels were highlighted using AHP. The study revealed that about 5.88% (2674.06 km2) of the island was categorized as highly suitable for a solar farm, 34.99% (15,908.21 km2) as suitable, 2.49% (1129.95 km2) as moderately suitable, and the majority, 56.64% (25,754.47 km2), was considered not suitable for solar projects. A solar power suitability map was developed as a reference for local governments and residents in establishing solar PV systems in their respective sites, thus maximizing the full potential of their land. The study also directs future solar power exploration studies in Sibuyan Island, supporting ongoing efforts to maximize solar energy utilization.

“…In addition, in most countries, they relate to primary energy, i.e., to a large extent fossil fuels, and are probably more challenging to decarbonize than electricity. Because the EU partner countries deal with emission reductions and their implementation differently, different paths and approaches should be distinguished, which in a given country enable the best reduction effect to be achieved [4,5]. Among the initiatives the EU took to accomplish these goals is the Effort Sharing Regulation, which is being updated as part of the Fit for 55 legislative packages.…”

Decisions regarding waste and emission management systems are subject to many sustainability criteria, including environmental, social, and economic criteria. The problem is the multidimensionality of the energy transformation and its reading from different perspectives. This article aims to assess the effectiveness of the municipal energy policy. The VIKOR multicriteria analysis approach to modeling and Criteria Importance Through Intercriteria Correlation were chosen for the method. The approach made it possible to create a ranking and choose a compromise solution. The analyses were carried out for four areas of intervention (ETS tariffs), in which a set of four general criteria and twelve specific criteria were distinguished, and based on the weights assigned, rankings were created highlighting the activities that have the greatest impact on low emission in urban areas. Based on the analyses, it was found that the most significant impact on reducing emissions in urban areas has led to decisions to increase investments in renewable energy sources and promote the reduction in household energy consumption.
