The aim of this work is to investigate the energy misperception of different sources among the “Next Generation” group. The analysis is carried out in Italy and the data were obtained through an internet-based survey, administered via Instagram to capture the Next Generation’s perception of the national energy mix. We found that younger have more misperceptions and one of the possible explanations could be that they are more negatively affected by media and social media, or public opinion in general. Another motivation could be that the younger generation considers sustainability important and therefore tends to over-perceive renewable energy sources.
