    The energy sector is one of the main emitters of greenhouse gases, making its transformation crucial in addressing climate change. In Colombia, although the electricity matrix is primarily based on hydropower, coal-fired plants remain essential to support the system during droughts, especially under El Niño events. This reliance on coal poses a challenge to meeting the country’s climate commitments. This research assesses the feasibility of converting coal-fired power plants into solar photovoltaic generation. The analysis incorporates solar potential in strategic regions, the current conditions of the national electricity system, and international comparative experiences. The results show that, although there is a favorable perception of the energy transition and the use of photovoltaic sources, intermittency emerges as a weakness that affects acceptance and operational reliability. It is concluded that successful transitions require strategic planning, community participation, and labor reconversion to ensure a just transition. Likewise, socioeconomic, cultural, and environmental conditions are decisive for the success of projects. The financial model developed shows that turning coal plants into to large-scale photovoltaic systems (>50 MW) is not currently viable under market conditions, although it improves significantly under scenarios of increased carbon tax and emission reduction certificates. These findings highlight the need for strong public policies and complementary technological solutions to enable the decarbonization of Colombia’s electricity sector.

    La economía circular en las pymes de la industria textil de Medellín y el Área Metropolitana del Valle de Aburrá
    (Universidad EAFIT, 2025) Betancur Villegas, Jorge Mario; Marín Ramírez, Diana Marcela; Uribe de Correa, Beatriz Amparo; Ng Henao, Robert
    The textile industry in Medellín and “el Valle de Aburrá”, with its long tradition and significant contribution to the local economy, faces pressing sustainability challenges derived from its linear operating model. This research addresses the need to move towards circular economy models as a solution to mitigate dependence on virgin resources, minimize waste and improve resource efficiency in the sector. Through a survey of 30 local textile companies, it seeks to establish the current level of adoption of circular economy principles, exploring aspects such as the sourcing of sustainable materials, waste reduction and the implementation of circular business models. The analysis of the results of this survey will provide essential empirical data on the actual state of circular economy adoption in the region, identifying common practices, key challenges, and future plans. This primary research is crucial to develop a relevant and effective implementation plan, tailored to the specific needs of the local context.
