Decree law 5/2024 amends Law 6/2022 on climate change and energy transition in the Canary Islands to streamline the processing of renewable energy and climate adaptation projects. Administrative efficiency measures are introduced and renewable energy penetration targets are established in the Canary Islands. Changes are made to the regulation of the electricity sector and land use to promote energy transition. The regulations also address emission reduction, energy efficiency, and climate change adaptation in the Canary Islands. [Extracted from the article]

The energy transition is Brazil's main policy in the context of adapting to and mitigating climate change, especially through the installation of wind energy projects. However, at the same time, the energy transition is used as a strategy to diversify the investment portfolios of transnational corporations, resulting in territorial impacts for communities located in the vicinity of these energy projects. The objective of this article is to discuss how the energy transition results in territorial impacts on the traditional fishing community of Enxu Queimado, located in the municipality of Pedra Grande, on the coast of the state of Rio Grande do Norte. To achieve this objective, quantitative and qualitative methodologies were used, including carrying out fieldwork in the community in the year 2023. With the research it is possible to conclude that the energy transition from the centralized energy generation model has been carried out from the violation of territorial rights of traditional communities, configuring the agrarian issue. The question is: energy transition or a new frontier for the expansion of capital? [ABSTRACT FROM AUTHOR]

Accelerating renewable energy deployment is imperative to address the climate crisis, yet projects commonly face community resistance and local cancellation. Accordingly, interest has risen in social impact assessments (SIAs) to evaluate social viability and strengthen management. However, mainstream approaches overlook upstream political economy dynamics that shape projects and drive opposition. Analyzing renewable developments in Mexico reveals how international negotiations and national policies produce rushed, large-scale projects in marginalized territories, igniting rural social struggles. While SIA practices can be enhanced, upstream policies constrain their scope to reshape misaligned projects and performance to address complex sociocultural contexts. This prompts questioning why vulnerable regions bear concentrated impacts and the need to explore alternative development pathways, despite SIAs implementation. [ABSTRACT FROM AUTHOR]

La energía solar fotovoltaica a diferencia de otras energías renovables, representa una de las alternativas más relevantes debido a su importancia, sostenibilidad y costo asequible, así como también una fuente primordial de electricidad de bajas emisiones proporcionando un funcionamiento óptimo de la red eléctrica. En este sentido, el presente texto tiene como objetivo exponer un trabajo científico especializado en el diseño de un sistema fotovoltaico (SFV) interconectado a la red eléctrica del Instituto Tecnológico de Los Mochis Campus Villa de Ahome (ITLMCVA), para la reducción de los gases de efecto invernadero (GEI) producidos por el consumo de energía eléctrica, con la finalidad de formar una institución educativa sostenible. Asimismo debido a la situación ocasionada por la emergencia sanitaria, se desarrolla un análisis en el cambio de los patrones en el consumo de energía eléctrica en el Instituto Tecnológico de Los Mochis (ITLM) ante el confinamiento del COVID-19, los cuáles han provocado un incremento de la demanda en el uso doméstico y un decremento de la demanda en las instituciones educativas.

This document summarizes a court case in Navarra, Spain, regarding the authorization of a wind energy project. The court ruled in favor of the regional government, stating that the project was not illegally divided and that the government had the authority to approve it. The court also dismissed concerns about the impact on bird species and protected areas. The court concluded that the wind farms should be considered as separate projects but acknowledged their shared infrastructure. [Extracted from the article]

Ecuador is a small Andean country located in the western hemisphere of South America. The country has 361;747hm3 annual superficial water resources; As a result, Ecuador, in the last fifteen years (2005 to 2020), has been rapidly developing hydropower projects to triple the production in this renewable source. There were eight new hydroelectric plants constructed in Ecuador among 2007 and 2015 invested close to USD 6 billion the projects. Increased the energy response with renewables; for example, in 1985, the country produced 4 TWh, in 2005-registered 7 TWh, and to 2020, 24 TWh. According to the Electricity Corporation of Ecuador in 2020 reported that generated around 80% of all electricity through hydropower; thus, the article aims to critically analyze the development of hydropower in Ecuador in recent years and establish general energy projections to 2030 to expand the fields of knowledge and perspectives. The paper methodology is quantitative, according to scientific editorial sources, articles, investigative documents, and collects data from government agencies that regulate energy development in Ecuador. It is conclusive between a projection's calculation, Ecuador will need for the year 2030 around 43 TWh, 47 TWh, or 52 TWh to supply the energy grid, according to the scenarios proposed (low, medium, high). Although hydropower will be essential to contribute to this requirement, the country has a barrier because hydropower is very sensitive to external factors of diverse nature, generating an uncertainly future directly associated with climatic effects.

This commentary presents the aspects considered most relevant on the novelties introduced by the legislative amendment of the European Union Directive 2018/2001 on the promotion of the use of energy from renewable sources. The European Union raises its targets for all Member States to meet by 2030 for a 55% reduction of greenhouse gases to achieve climate neutrality by 2050. To do so, a procedural simplification in the granting of administrative authorizations has been proposed, where the implementation of renewable acceleration zones with permit-granting procedures and the implementation of the overriding public interest stand out, as well as various modifications in the field of transport, buildings and industry. As final considerations, some of the reflections on the potential effects that the Directive will have. [ABSTRACT FROM AUTHOR]

Brazil is a tropical country with favorable conditions for the generation and utilization of solar energy. This energy source becomes even more attractive when considering the dry periods that impact hydroelectric power generation in the country, resulting in an increase in energy costs reflected monthly in consumers' bills through tariff flags. In order to enhance residential architectural designs and promote energy efficiency, a feasibility study of photovoltaic systems was conducted, considering key economic indicators and the current tariff flags. To accomplish this, research was conducted in collaboration with Mounting Companies for a case study located in the city of Rio de Janeiro, adopting technical assumptions commonly used for residential photovoltaic system sizing. For the graphical sizing of the case study, factors such as the environment and summer and winter solstices were taken into account, and a shadow study was conducted to assess the potential loss of power generation by the photovoltaic system throughout the year. The shadow study revealed that, during both solstices, the optimal time for power generation by photovoltaic systems is between 9 a.m. and 6 p.m. Essentially, the calculated values of NPV (Net Present Value) and IRR (Internal Rate of Return) indicate that the project is economically viable and particularly advantageous during the yellow and red tariff flags, situations in which energy costs tend to be higher for consumers.

Atmospheric pollution and accelerated environmental deterioration for the increasing use of fossil fuels have directed research in the energy field towards the search for alternative, renewable, efficient and, above all, more environmentally friendly sources. Among the raw materials that are of great interest in the generation of biofuels are lignocellulosic residues, which are currently produced in abundant quantities, either by the simple action of nature or because they are part of the agro-industrial chain of a given region. For this reason in the present work, the biomass of Eucalyptus globulus was evaluated as a low-cost and widely available source for obtaining liquid biofuel, for which a preliminary physical and chemical characterization was carried out, by considering established standard specifications. Thermochemical conversion tests were carried out by pyrolysis in an N2 atmosphere and through the application of a factorial experimental design (22) contemplating the influence of experimental variables such as residence time and temperature, it was possible to obtain at 550 °C and during 20 min of reaction, a bio-oil with a maximum yield of 45,2 % and whose physical and chemical properties are within the range estimated in the literature for biofuels of lignocellulosic origin, such as the calorific value (16,7 MJ/kg). Therefore, the biomass of Eucalyptus globulus can be considered as a raw material with potential to be explored in the generation of energy. [ABSTRACT FROM AUTHOR]

The article identifies an empirical blind spot in the literature on hydro-hegemony, with a scant analysis of power relations and resource control between states in transboundary water relations in a Latin American context. This article aims to fill this gap by examining Brazilian hydro-hegemony in the case of the Brazilian–Paraguayan Itaipu hydroelectric dam, the second-largest hydroelectric dam in the world by production. Based on a literature review and analysis of interviews with regional experts, it is argued that Brazilian hydro-hegemony can be best understood as consensual hegemony, resulting in consensual hydro- hegemony as a distinct and understudied form. In the Itaipu case, Brazil established such a hydro-hegemony through the dam's binational administrative company, containing Paraguay within a structure that leads to Brazil-skewed resource control.

El gran desarrollo que ha mostrado la energía renovable como estrategia central de la denominada transición energética ha provocado importantes impactos en el territorio. Estos incluyen desde conflictos con otras actividades económicas hasta la invasión de paisajes de gran valor cultural. Estas intersecciones, con ciertas particularidades, también se aprecian en ciertos contextos litorales en los que se están implementando nuevas tecnologías tanto en mar como en tierra para la obtención de energía. Atender a este contexto específico desde su dimensión espacial por parte de la arquitectura y desde una noción amplia de la idea de paisaje puede permitir importantes aprendizajes para el proyecto de la energía. Este trabajo presenta un análisis de tres casos de estudio como ejemplos relevantes de los procesos emergentes de ocupación del litoral europeo: el parque eólico de Middelgrunden, la planta undimotriz de Mutriku y la infraestructura mareomotriz del estuario del Rance. El estudio realiza una relectura de sus aspectos espaciales desde una mirada arquitectónica y define estrategias de diseño que relacionan la infraestructura energética litoral con su contexto paisajístico y sociocultural específico, proponiendo así relaciones transversales que pueden incorporarse a los procesos de integración multidisciplinares para futuros escenarios de la energía en la costa.

En la actualidad, la expansión y mejora de los sistemas de energía eléctrica se realiza de manera integral. Esto hace que en los sistemas actuales se busque la incorporación de nuevas tecnologías y enfoques en el marco de la Industria 4.0. A raíz de esto, una de las tecnologías que ha cobrado importancia en los últimos años es la de los llamados gemelos digitales. Un gemelo digital es una representación virtual, parcial o completa, de un sistema físico o proceso que permanentemente evoluciona a la par del sistema o proceso real. Un vehículo, una turbina eólica o una ciudad entera pueden representarse mediante gemelos digitales. Para implementar y operar estos gemelos digitales es necesaria la utilización de sensores en el sistema físico o proceso para recoger información en tiempo real del estado de funcionamiento que permite adaptar el comportamiento simulado. Este estudio tiene como objetivo promover la aplicación de la tecnología de gemelos digitales en sistemas eléctricos, además de discutir los desafíos para su implementación. Se presenta una propuesta para el desarrollo y aplicación de la tecnología de gemelos digitales en diferentes campos, con preferencia en el de la generación eléctrica.

In this work, a study was carried out on the opportunity that exists in Cuba to use deep sea water as a renewable alternative for air conditioning. It identified the main coastal areas where the required depth could be accessed at a rational distance from the shore and the possible users with the greatest potential for this type of technology. Each place had its own characteristics so, as an illustration, a specific area was chosen for a case study, with the aim of evaluating the energy, economic and environmental impact that could be achieved by replacing the current conventional systems of vapor compression air conditioning. Input variables and maps were obtained from publicly available information and the rationality thresholds of a given project were identified through exergoeconomic analysis. [ABSTRACT FROM AUTHOR]

Con base en los acuerdos para un desarrollo sustentable no solo en el país sino en todo el mundo empresas y gobiernos suscriben acuerdos para colaborar en el alcance de metas que además de incentivar el desarrollo económico posibilitan consolidar más de uno de los objetivos del desarrollo sostenible. Este estudio pretende analizar el impacto que los equipos que funcionan con combustibles fósiles pueden en alguna medida coadyuvar en resarcir los efectos nocivos del uso de estos con el pago de contribuciones por usarlos o dejarlos de usar cuando los sustituyes por equipos que funcionan a partir de recursos renovables. A partir de una investigación de enfoque cualitativo con un análisis exploratorio-descriptivo y explicativo de disposiciones y estudios de expertos que faciliten concretar las ventajas y desventajas que representa el uso y el consumo de combustibles tradicionales con respecto a los que usan los bienes procedentes de la naturaleza como: el agua, el viento o el sol; que en las leyes nacionales pueden castigar o premiar con contribuciones o incentivos fiscales permitiendo a las administraciones públicas no solo revestir su presupuesto sino también cumplir compromisos suscritos con anterioridad. Lo que se pretende con éste es conocer los resultados de acuerdo con las disposiciones fiscales vigentes en México sobre el cumplimiento que se puede lograr al 2030 asumiendo las contribuciones o los incentivos de acuerdo con las tecnologías que se usan en los equipos de los entes económicos del país; además de los registros contables se necesitan alternativas en la nueva era del conocimiento.

El propósito de la presente investigación es analizar las nuevas tendencias relacionadas con la implementación e incorporación de las energías, amarillas, azul y verde en Colombia1, así como su incidencia no solo en el campo laboral sino también en el ordenamiento jurídico y económico. La metodología utilizada se fundamentó en el paradigma positivista y enfoque de investigación cuantitativa, de tipo documental y nivel exploratorio, adicionalmente se complementó con la hermenéutica analógica para la contrastación e interpretación de información, en esta investigación se resumen los resultados obtenidos hasta el mes de mayo de 2022. Los principales resultados dan cuenta de una efímera implementación de mecanismos de transformación energética, en todas sus modalidades, aunque existen proyectos en marcha que demuestran que se están dando pasos ordinales hacia las metas establecidas. De igual manera estos destacan que se debe dar impulso al salario de los colombianos en razón a que lo devengado no le permite al 60% de los trabajadores acceder con sus propios medios a este tipo de tecnologías y coadyuvar con el avance en la implementación de este nuevo paradigma energético. Como principal conclusión, se observa que un gran segmento de la población laboralmente activa devenga salario mínimo y por tal razón el Estado debe participar con una política pública determinante en la subvención de estas tecnologías para avanzar de forma exponencial en la transformación energética renovable.

El proceso de Transición Energética y la implantación exponencial de tecnologías de generación renovable está generando algunos confl ictos sociales y económicos en el territorio. Estos confl ictos están dando pie a movilizaciones ciudadanas y movimientos políticos en contra de las instalaciones de energías renovables (fotovoltaica y eólica) en zonas rurales. El debate actualmente abierto, en grandes líneas, enfrenta la protección del territorio y la defensa del mundo rural, contra la transición del modelo productivo de energía a uno basado en tecnologías renovables instaladas en grandes plantas de generación. Sin embargo, existen múltiples casos donde el desarrollo se ha realizado de la mano del territorio, cuidando la gobernanza del proceso y la distribución de los benefi cios. Aquí desarrollamos los casos de instalación de energías renovables en Muras (Lugo), Revilla-Vallejera (Burgos), Sant Jordi (Castelló), un proceso de escucha en el Matarraña aragonés y una modalidad de contratos de arrendamiento agrario, donde diferentes acciones y políticas implementadas por parte de todos los actores han facilitado la aceptación de la implantación de energías renovables. Así, analizando buenas prácticas, podemos replicar acciones exitosas que garanticen el desarrollo de una Transición Energética justa, equilibrada y rápida, la cual requiere de consensos políticos, buenas prácticas empresariales y de la complicidad ciudadana.

Royal Decree 662/2024 establishes the regime for the installation of floating photovoltaic plants in reservoirs under the management of the General State Administration. The aim is to promote renewable energies and adapt existing regulations to regulate these installations. Technical and legal requirements are established to obtain concessions and monitoring programs will be implemented to assess possible environmental impacts. The regulations affect the hydrographic basins under state jurisdiction and define floating photovoltaic plants as projects for the production of electric energy in water.

Actualmente, la dependencia a los recursos fósiles sigue dominando, aún con los impactos económico-ambientales que estos generan; por lo que es necesario incentivar la producción y uso de fuentes renovables, asequibles y sustentables. En este sentido, el presente trabajo se enfoca en desarrollar un software de simulación termosolar para la evaluación de materiales de bajo costo y bajo impacto ambiental que puedan ser utilizados en calentadores solares o acumuladores térmicos. Optimizando el uso de materiales pétreos, orgánicos y aquellos disponibles localmente con propiedades optotérmicas de alta absorción y gran residencia térmica, para utilizarlos como contenedores de energía termosolar. De este modo, se ha desarrollado una aplicación de escritorio en lenguaje de programación Python, para simular la absortancia y acumulación térmica de materiales con las características mencionadas utilizando propiedades como temperatura ambiente del lugar de prueba, absortancia solar, conductividad térmica y masa del material. Este software pretende eficientar los procesos experimentales, reduciendo recursos económicos, tecnológicos y materiales, al contar con un modelo de la física térmica de acumulación termosolar en materiales naturales, prediciendo su comportamiento energético sin la necesidad de construir prototipos a escala real. Finalmente, se ha comprobado que el simulador desarrollado, proporciona un análisis mucho más dinámico y fácil de interpretar con datos estadísticos de fácil obtención. Es decir, permite observar no solo la curva sino también proporciona la dispersión de un sistema continuo de valores, el cual puede ayudar a inferir los datos de una investigación con mayor sencillez y efectividad sobre las propiedades ópticas y térmicas de los materiales estudiados. No obstante, el desarrollo del programa computacional puede ser mejorado, por lo que mantiene un esquema de libre acceso y código abierto.

El mundo es cada día un lugar más convulso y conflictivo a nivel geopolítico y con los conflictos tanto diplomáticos como militares de los últimos tiempos los países pueden temer, con cierto sentido, que su suministro energético no esté garantizado si dependen de terceros países para obtenerlo. Es necesario el fomento urgente de la investigación y utilización de fuentes de energía renovables que permitan al Estado autoabastecerse y para ello uno de los mecanismos a utilizar puede ser la contratación pública estratégica. Es intención de este trabajo abrir la posibilidad a las Administraciones de añadir en la mayoría de las licitaciones un requisito de uso de energía renovable durante la realización del objeto del contrato. Para ello se estudiarán las vías legales y jurisprudenciales para ver si ello es posible y acorde a los principios de contratación pública, así como se especificará la forma en que es posible acreditar el uso de dicha energía y las vicisitudes que envuelven a la certificación, conocida como “Garantías de Origen”.

La contaminación atmosférica y el acelerado deterioro ambiental por el creciente uso de combustibles fósiles, ha direccionado las investigaciones en el campo energético hacía la búsqueda de fuentes alternativas, renovables, eficientes y sobre todo más amigables con el medio ambiente. Entre la materia prima que cobra gran interés en la generación de biocombustibles, se encuentran los residuos lignocelulósicos que actualmente se producen en abundantes cantidades, ya sea por simple acción de la naturaleza o porque hacen parte de la cadena agroindustrial de una región dada. Es por ello que en el presente trabajo se evaluó la biomasa de Eucalyptus globulus, como fuente de bajo costo y amplia disponibilidad en la obtención de biocombustible líquido, para lo cual se llevó a cabo una caracterización física y química preliminar teniendo en cuenta especificaciones establecidas en normatividad del sector. Se realizaron ensayos de conversión termoquímica por medio de una pirólisis en atmósfera de N2 y a través de la aplicación de un diseño experimental factorial ( ) contemplando la influencia de variables experimentales tales como tiempo de residencia y temperatura, fue posible obtener a 550 ºC y durante 20 min de reacción, un bioaceite con un rendimiento máximo del 45,2 % y cuyas propiedades físicas y químicas se encuentran dentro del rango estimado en literatura para biocombustibles de origen lignocelulósico, tal es el caso del poder calorífico (16,7 MJ/kg). Por lo tanto, la biomasa de Eucalyptus globulus puede ser considerada como materia prima con potencial a ser explorado en la generación de energéticos.

Las fuentes de energía no renovables (fósiles y nucleares) están doblemente limitadas, tanto por su finitud como por los perjuicios ecológicos y sociales que causan. Las fuentes de energía renovable tienen flujos en la biosfera muy grandes, sin embargo, los sistemas tecnológicos que las captan no son renovables y por tanto tienen limitaciones tecnológicas, ecológicas y sociales también. Aunque una buena parte de la literatura científica ha venido estimando que estos factores limitantes son pequeños frente a los políticos y económicos, aquí se muestra que esta literatura ha venido sobreestimando la capacidad tecno-sostenible obtenible a lo largo del presente siglo, en buena medida por un tecno-optimismo implícito y una falta de pensamiento sistémico. Este potencial podría ser del orden de entre la mitad y la cuarta parte del uso actual de energía, lo que apunta, dada la necesaria transición hacia fuentes renovables por problemas ambientales, a un fuerte decrecimiento de la matriz energética que sostiene nuestras sociedades a escala global.
