Background This study analyses how Spanish digital media frame biorefineries, a key renewable energy technology in the country’s energy transition. It draws on theories of social acceptance of renewable energies and the political economy of communication to examine how power asymmetries in media coverage influence public perception and participation. Methods A mixed-methods discourse analysis and social listening approach was applied to a corpus of 350 media articles (88 unique cases) published between 2019 and 2024 and collected through Onclusive Social. Articles were coded according to actor presence, argument type, tone, territorial context and socioeconomic indicators. Reliability was ensured through double coding and Cohen’s kappa statistics. Results The analysis reveals a marked dominance of corporate and institutional actors in shaping narratives, with economic arguments strongly associated with positive coverage, while environmental and health concerns predict negative tone. Rural areas display more critical discourse than urban ones, challenging conventional NIMBY explanations. From these findings, the study derives the Communicative Hegemony Model in Energy Transition (CHMET) as a conceptual outcome that integrates observed patterns of media power and proposes axes for future testing and comparative research. Conclusions Spanish media discourse on biorefineries reflects structural imbalances that may condition social acceptance of renewable energy projects. Policy recommendations include strengthening independent scientific communication, promoting binding public deliberation and enhancing journalistic standards to balance stakeholder voices. By presenting CHMET as a product of the analysis and a framework for deeper investigation, the study contributes both empirical evidence and a conceptual tool to advance research on communicative power in energy transitions.

En las últimas décadas, las tecnologías inmersivas han creado nuevas posibilidades para la producción audiovisual, facilitando al usuario interactuar de manera directa en el relato y haciéndole partícipe de este. Esta investigación presenta un análisis centrado en el proceso de producción de un vídeo 360º cuyo objetivo es mostrar, de forma sencilla, procesos industriales complejos, como la valorización de productos de valor añadido mediante pirólisis catalítica. A través de este estudio de caso, se describen las etapas de preproducción, producción y postproducción, detallando las decisiones narrativas y técnicas para el uso del formato de vídeo 360ª. Los resultados presentan un estudio de caso basado en la realización de un proyecto inmersivo orientado a la sensibilización medioambiental y la ecoalfabetización de los usuarios. Busca, a través de un formato novedoso, facilitar la comprensión de conceptos industriales complejos. Las conclusiones ofrecen una guía para la replicación de este producto aplicado a contenidos de educación y comunicación científica.

Esta investigación analiza el impacto de la Inteligencia Artificial Generativa (IAG) en la creación de contenidos audiovisuales y multimedia mediante un estudio comparativo de Recursos Educativos Abiertos (REA) desarrollados (n = 121) en dos MOOC enfocados en combatir la desinformación, donde uno emplea IAG y el otro no. El análisis compara tanto los procesos de producción como los resultados obtenidos en dimensiones clave como eficiencia, calidad técnica y formal y accesibilidad a las herramientas. Los resultados muestran que la IAG mejora la eficiencia y calidad en la producción de los rea, facilitando la creación de contenidos de alta calidad con un menor costo. Su uso permite producciones más accesibles y escalables ampliando las posibilidades de creación de contenido educativo digital avanzado.

Background This study examines the scientific misinformation about climate change, in particular obstructionist strategies. The study aims to understand their impact on public perception and climate policy and emphasises the need for a systemic understanding that includes the financial, economic and political roots. Methods A systematic literature review (SLR) was conducted using the PRISMA 2020 model. The sample consisted of 75 articles published between 2019 and 2023, sourced from Web of Science, Scopus and Google Scholar. Methodological triangulation was performed to improve the analysis. Results The results show that technological approaches to misinformation detection, such as immunisation and fact-checking, are widely used. However, few studies look in depth at the operational structures that support systematic disinformation. Conclusions The study emphasises the urgent need to expand and deepen research on climate disinformation and argues for more global, comparative and adequately funded studies. It emphasises the importance of addressing the systemic complexity of disinformation and integrating different theoretical and methodological approaches. This will help to develop effective measures against hidden networks of influence and mitigate their disruptive effects. The research findings are relevant for policymakers, scientists, academics, the media and the public and will help to improve strategies to combat climate misinformation and promote science-based climate action.
