Resumen: La difusion y penetracion de medidas de uso eficiente de energia tienen impactos positivos tanto sobre la competitividad como sobre las condiciones de seguridad de las firmas. Empero, tales impactos son dificiles de alcanzar en la practica debido a la presencia de barreras que limitan la toma de decisiones por parte de los agentes economicos. Este trabajo identifica, evalua y valora una serie de barreras al uso eficiente de energia en microempresas de Medellin (Colombia). Mediante el metodo Proceso de Analisis Jerarquico, se encuentra que la ausencia de incentivos, los altos costos iniciales de inversion, la falta de conocimiento e informacion del empresario, la falta de disponibilidad de equipos eficientes y los riesgos tecnicos son las principales limitantes. Algunas estrategias para contrarrestarlas, plantean que la informacion debe responder al contexto especifico, los instrumentos economicos considerar politicas de precios e incentivos financieros, y la regulacion el establecimiento de estandares para mejorar parametros tecnologicos.Abstract: The diffusion and penetration of energy efficiency measures have positive impacts on both the competitiveness and the security conditions in which firms operate. However, these impacts are difficult to achieve in practice due to the presence of barriers that limit the decision-making process by economic agents. This research identifies, evaluates, and ranks a number of barriers to the efficient use of energy in the microenterprises of Medellin (Colombia). We used the Analytic Hierarchy Process method, finding that the absence of incentives, the high initial investment costs, the lack of knowledge and information by managers, the lack of availability of efficient equipment, and the technical risks are the main constraints. Some strategies to offset their impact highlight that information must respond to the specific context to be effective, economic instruments must account for pricing and financial incentives, and regulations must deal with establishing standards to improve technological parameters.
