An attempt was made to respond to a very complex programme on energy sources throughout history and what are the alternatives for the future. More than ten nuclei respond with a multitude of solutions. From the traditional exhibition to the most advanced interactivity, large format videos and models provided an overview of the country's history, offering various experiences. Games and infographics complemented the contents that had to serve a differentiated public. The project modulated the spaces, thought out the lighting and sound design, and also solved relevant aspects of the institutional communication of the pavilion that, with others, integrated one of the central buildings of the venue.
