The cycle Light everywhere takes as its title a quote from promotional material published between the 1920s and 1950s by one of the companies that historically preceded EDP. The EDP Foundation Documentation Centre is the faithful custodian of this vast legacy (graphic models, flyers, printed leaflets, and posters, among other media) of both advertising and educational nature. Displaying it to the museum’s public means showing an important moment in Portuguese society: the period when domestic electrification became widespread in towns and cities, and companies needed to attract an increasing number of consumers by extolling the advantages of the new source of energy and light while also teaching them how to use and consume it rationally. The second part of this cycle is dedicated to the Junqueira Power Station.
