Renewable energy sources are central to decarbonization, and social support for their expansion is linked to how citizens understand and evaluate the energy transition. This study examines attitudes towards Renewable Energy Sources (RES) among 408 Generation Z respondents in Italy, Lithuania, Morocco and Poland, providing the possibility to compare different energy contexts, while using a common questionnaire on the same attitudinal dimensions across samples. Country-specific OLS regressions with forward variable selection were used to analyse associations between attitudes towards RES and a set of cognitive, evaluative and behavioural measures. Climate-change importance is the only correlate appearing in all four final models, while the other selected correlates differ across countries. The results therefore point to a common climate-related association within otherwise country-specific patterns in Generation Z attitudes towards renewable energy. By applying a common questionnaire and the same modelling strategy to four Generation Z samples, the study provides a structured comparison of RES attitudes across contrasting national energy contexts. This design makes it possible to examine which associations recur across the four samples and which appear only in particular specifications.
