The National Energy Balance (NEB) is used to show the main ways in which the country's various renewable and non-renewable energy sources are used and exploited. The main object of this study was the National Energy Balance (BEN). The general aim of this work was to train teachers and improve the subject in an approach that respects the guidelines of the ENEM model, making it more accessible as support material for research at different levels of learning, while also showing through BEN which energy alternatives can be more successful in various environmental aspects.
