El desarrollo de la energía eólica en escala mundial es notable, representando ya una parte importante de la capacidad eléctrica global con fuentes renovables. La industria eólica mundial enfoca su atención hacia países en desarrollo con locaciones idóneas para la instalación de centrales eólicas. En México, el sur del istmo de Tehuantepec es la región con mayor potencial eoloenergético y donde se concentra el despliegue de proyectos eólicos. Se examinó el desarrollo eólico en esa región y sus actores principales. Se analizaron diversos aspectos desde lo relativo al derecho a la información, hasta las implicaciones ambientales a fin de comprender la creciente oposición social a la instalación de proyectos en esa zona. El modelo de explotación eólica imperante en el istmo de Tehuantepec favorece a las empresas desarrolladoras, limitando los beneficios para las comunidades locales y acrecentando el rechazo social a los proyectos.
Biogas technology represents an option to enhance sustainable energy use in developing nations particularly in the rural context. However, the production and use of biogas could also take place in urban settings in these countries with potential benefits for their sustainability. The present work introduces a set of nine indicators in the economic, social and environmental sustainability dimensions for assessing the impact of a small-scale biogas plant on the energy sustainability of a restaurant located in Mexico City. Indicators were evaluated before (base scenario) and after (biogas scenario) biogas plant installation and then they were linearly normalized using a scale between 0 and 1 corresponding to a growing level of energy sustainability. Economic dimension indicators averaged 0.67 in the base scenario and 0.68 in the biogas scenario; those of the social dimension, 0.52 and 0.54; and those of the environmental dimension, 0.17 and 0.49, respectively. Results indicate a positive impact of biogas plant on restaurant energy sustainability. These indicators provide objective elements to examine in detail biogas contributions in strengthening energy sustainability of cities in developing countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
