This study presents a 100% renewable and diversified system taking advantage of the available energy potential of renewable energies in Mexico with a view to a planned energy transition in cooperation with the environment. The processes of change that are experienced worldwide in favor of the planet make us reflect and propose alternatives that break traditional schemes in the production of energy (for which reason Mexico cannot deviate from its current model). It is here that this research becomes a transcendental and important reference for decision-making and the transformation of the energy sector in Mexico. The current electrical system relies on fossil fuels that need to be replaced by renewable energy sources (and it is necessary to satisfy growing demands in the long term). The methodological process is carried out with the use of the 100% renewable energy market design tool EnergyPLAN, which puts the concept of intelligent energy into practice by 2050. Finally, after analyzing the results, it is concluded that a good energy mix for 2050 is 30% solar photovoltaic, 25% wind, 14.5% hydraulic, 13.8% CSP plants, and 16.7% other technologies. Surpluses may be sold to the United States and Central America through interconnection points.

Los aerogeneradores de eje horizontal de potencia de 1 kW, ofrecen una alternativa viable para la generación de energía limpia en hogares. Mediante la aplicación de los modelos teóricos de Rankine-Froude y Elemento de Pala, este trabajo presenta un diseño detallado que contribuye a la reducción de la dependencia de fuentes de energía fósiles y promueve la sostenibilidad energética. En el presente trabajo, se muestra detalladamente el proceso de diseño de un aerogenerador de eje horizontal con una potencia de 1 kW empleando el modelo teórico de Rankine-Froude y modelo del Elemento de Pala, para las cuales se trabajó con perfiles NACA de cuatro dígitos con una ordenada de 0.4 al 40 % de la cuerda, con diferentes espesores con MATLAB® se ha calculado el perfil alar para posteriormente construir el aerogenerador. El análisis estadístico del recurso eólico (10 m de altura) para la ciudad de Saltillo, Coahuila, México, donde se han realizado las pruebas de funcionamiento muestra que con una velocidad mínima de 6 m/s se puede generar energía eléctrica.

Luxury beach hotels in tropical climates are large consumers of electricity, negatively impacting the environment and their profit margins. Energy efficiency and the incorporation of clean energy are among the main actions contributing to reducing this problem, but the implementation of this second solution is minimal among these types of hotels. A case study was conducted and found that this is primarily due to a lack of space in their facilities. Solutions are proposed by implementing agrovoltaic farms in the areas adjacent to the destination studied. The project is technically, economically, and legally feasible, and the proposed agrovoltaic farms could supply nearly 580 million kWh annually, mitigating emissions of just over 390,000 tCO2e/year and making Puerto Vallarta and Nuevo Vallarta a "Green Destination," thus contributing to meeting international GHG mitigation targets.

The agricultural and livestock sectors of Latin America produce a large number of residues that could be converted into energy through bioenergy production processes. However, the bioenergy sector still faces several limitations across the region, including fragmented logistics systems, weak coordination among institutions, and limited integration of environmental, digital, and compliance-related performance indicators. This review systematically analyses residue-based bioenergy value chains in Latin America between 2015 and 2025 using the PRISMA methodology to evaluate selected peer-reviewed studies and regional reports indexed in Scopus, ScienceDirect, SpringerLink, and IEEE Xplore, and institutional repositories. The final synthesis included 37 studies and institutional contributions, which were further disaggregated into 208 country–residue observations for the regional and feedstock distribution analysis. The review identified three main research gap categories: the limited integration of collection and logistics systems, the insufficient treatment of uncertainty, circularity, and traceability within optimization models, and the weak incorporation of governance and institutional coordination into bioenergy value-chain design. The analysis includes biogas, biomethane and related residue-based systems, with attention to supply-chain optimization, policy alignment, methane mitigation metrics, and traceability requirements. Results indicate that although technologies such as biomass pretreatment, process intensification, and upgrading processes continue to improve conversion performance, most studies still focus mainly on technical feasibility and biomass potential. Less attention is given to governance constraints, uncertainty analysis, and monitoring systems capable of supporting regulatory compliance. This research introduced the Sustainable Bioenergy Chain Management Framework (SBCMF) to respond to these limitations and bring together different aspects of bioenergy management within one analytical structure. The framework combines supply-chain optimization under spatial and temporal constraints, circular economy valorisation, methane-related climate performance, and digital traceability, while also linking techno-economic system design with governance and monitoring requirements. In this way, it can help support the development of more transparent and low-carbon bioenergy systems across Latin America.

We present the design of a prototype solar photovoltaic system interconnected to the electrical network based the Standard CONOCER Mexico EC 0586.01 with which students from Polytechnic Universities and other education institutes technological of renewable energy acquire the theoretical-practical knowledge of photovoltaic technology, for so that students professionals more competitive. The prototype is designed using SolidWorks® software, is design for small space by the dimensions that have and is easy transportation because it does not weigh. The implementation consist in connections between components and the corresponding connections to the electrical grid and determine the acceptance by users through questionnaires applied. The characterization consist in acquired real-time physical and electrics parameters by computational tool designed, the graphs of characteristic curves of solar panels as function of solar irradiance and graphics of energy production of the photovoltaic system. Finally the use of the electricity network to supply an electric demand not covered by the prototype of grid interconnected photovoltaic system.
