This article describes the stages to establish an energy management in a company from the industry sector. The methodology applies basic statistical and mathematical concepts to understand consumption phenomena in a machine, a production line or a general process. Colombian managers do not invest in such projects because they ignore the scope they have and, despite the fact that our electric market is not regulated and is very efficient compared to others in the world, there are not clear policies to define and support investments on rational energy use projects.esCorporación Universitaria LasallistaUso racional de energía (URE)Administración energética empresarialConsumo de energíaEficiencia energéticaMercado energético-ColombiaGestión energética empresarial una metodología para la reducción de consumo de energíaEnergy management in business a method to reduce energy consumptionEmpresa de Gestão de Energia Uma Metodologia para a Redução de Consumo de EnergiaArticle
