The exhibition "Conectados. Energía y Econciencia, 1970 2023" is an initiative of the Spanish Ministry for Ecological Transition and the Demographic Challenge, which reviews some of the governmental advertising campaigns from the 1970s to the present day. It also shows the contexts in which these campaigns took place, recalling the uses and everyday objects. Finally, the project addresses the challenges of the future in terms of transforming the use of energy and its sources. The exhibition was on view at Matadero Madrid in mid-2023 and then travelled to La Térmica Cultural de Ponferrada / Museo Nacional de la Energía. The lightweight exhibition set-up, designed for the occasion by Estudio AMPS and assembled by Museoteca, minimizes the ecological footprint to the maximum, thanks to an ingenious modular system in cardboard that not only has little or no impact, but is also easy to assemble and disassemble.
