Ítem Floating photovoltaics systems on water irrigation ponds: Technical potential and multi-benefits analysis(Elsevier, 2023-05-15) Muñoz-Cerón, Emilio; Osorio-Aravena, Juan Carlos; Rodríguez-Segura, Francisco Javier; Frolova, Marina; Ruano-Quesada, Antonio AntonioFloating photovoltaic systems (FPV) can be a more sustainable alternative for the energy transition than ground-mounted photovoltaic systems, as they avoid occupying useable land and the power generation is more distributed. This paper presents the first study that calculates the FPV technical potential at the province/municipality level, focusing on water irrigation ponds, which it is a novelty in the literature that usually focuses on large water infrastructures in a national approach. In the province of Jaén (Spain), more than 3000 ponds dedicated to agricultural irrigation have been identified and their surface area and location was obtained. The results, calculated for each pond, reveal that, in a conservative scenario, in which only 25% of their surface area is covered, a minimum of 490 MWp can be installed, which can provide 251% of the province agricultural electricity consumption and 27% of the total electricity needs. This analysis has also been performed at the municipal level, where all possible FPV plants have been aggregated and compared with consumption that would be covered at this scale. Furthermore, this technology brings additional benefits, as it avoids the occupation of 12 km2 of useable land, 8.8·106 m3/year of water evaporated, while creating more than 7000 jobs.Ítem How much solar PV, wind and biomass energy could be implemented in short-term? A multi-criteria GIS-based approach applied to the province of Jaén, Spain(Elsevier, 2022-05) Osorio-Aravena, Juan Carlos; Rodríguez-Segura, Francisco Javier; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioThe progress made in the penetration of renewable energy (RE) sources in most parts of the world is not fast enough for achieving the international climate mitigation targets. Furthermore, there is a lack of energy planning strategies, methods and tools for assessing the implementation of RE technologies which considers the social support. In this work, we present a replicable multi-criteria spatial approach based on geographical information system to estimate the potential of solar photovoltaic (PV), wind and biomass energy technologies that could be implemented in the short-term in a given territory. This potential includes environmental, technical (with economic attributes) and geographical (with social-acceptability attributes) constraints, together with existing local power plants considerations for calculating the electricity generation by technology, and then estimating its jobs creation and greenhouse gas emissions reduction. The approach was applied to the province of Jaén (Southern Spain), which has a pronounced unbalance between its inner electricity production and consumption and apparently is a territory with great technical potential for the aforementioned technologies. Results show that this province has a short-term implementable potential that would annually produce 8.9 TWh from solar PV, 911 GWh from wind energy and 683 GWh from biomass plants; which is 3.8 times greater than the current electricity consumption and would require 1.5% of the total surface of Jaén. This potential can create about 92,800 direct jobs and avoid the emissions of 3.78–8.61 MtCO2 to the atmosphere. The proposed approach can be useful for energy planning processes and for allowing decision-making to accelerate the implementation of RE power plants in order to achieve the climate mitigation goals.Ítem Social acceptance of renewable energy development in southern Spain: Exploring tendencies, locations, criteria and situations(Elsevier, 2023-02) Rodríguez-Segura, Francisco Javier; Osorio-Aravena, Juan Carlos; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioAlthough, in general, there is a high level of public acceptance of renewable energies (RE) in Spain, at a local scale, protests and campaigns against RE projects are becoming increasingly frequent. In order to identify the factors that most influence the acceptance/rejection of renewable electricity generation technologies (photovoltaic, wind and biomass) at a local level, in this study we conducted a structured survey of the population of the province of Jaén in southern Spain. The analysis of the results of the questionnaire reveals that the social acceptance of RE plants is influenced by their location and size, and identifies the main criteria and situations that people take into consideration when deciding whether to support or reject RE projects. Although the results suggest that all RE technologies are widely accepted, they also highlight a preference for photovoltaic energy and for medium-sized plants in sites with low natural value. This article provides information and recommendations to facilitate the drafting of policies, plans and future studies that will enable social barriers to the implementation of RE technologies to be reduced, so helping accelerate the energy transition that is required in order for agreed climate targets to be met.Ítem Spatial Energy Planning: A Review(MDPI, 2020-10-15) Osorio-Aravena, Juan Carlos; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioDespite the fact that some renewable energy (RE) technologies are already techno-economically viable, the high spatial dilution nature of their sources, together with aspects beyond the techno-economic ones (such as environmental, social, cultural, and other aspects), can become strong constraints and barriers when it comes to their integration into electric systems. Therefore, with the objective of determining whether studies on spatial energy planning (SEP) are addressing these issues, a systematic review has been carried out to address whether SEP studies are considering aspects beyond the techno-economic ones when integrating RE technologies and, if they are being considered, how they are addressed in their analyses and what criteria, factors, and indicators of the aspects that are employed. Apart from the revelation that the concept of SEP has been included within high-quality scientific literature for less than ten years, SEP seems to be an unexploited tool with the potential to provide significant insight into a planning process that could prevent conflicts when integrating RE technologies into electric systems. This would be useful for decision-makers and for accelerating a sustainable energy transition.
