Concern about energy depletion has risen because of industrialization and consumerism, pushing a transition from fossil fuels to renewable energy sources. To this end, every group within society, especially the youth, should be made responsible for confronting and/or mitigating environmental problems. This study advances the understanding of young adults’ intentions to learn about energy conservation and its influencing factors, as well as contributes to the literature on environmental management and environmental culture and development. We used a systematic random sample technique to conduct a large-scale online survey with 1454 students from 48 different Vietnamese universities and employed Bayesian regression model to analyze the data. The initial research indicates that young adults are highly concerned about the environment, but more work has to be done to turn perceptions into actions. The majority of respondents—nearly 83%—want to increase their energy-saving knowledge, and around 50% are interested in enrolling in an energy course. Their decision regarding participation in an energy course is largely influenced by their perception and income. Women were more inclined to take energy-saving courses, and people who lived in rural areas had a stronger desire to increase their knowledge. Our research has various policy implications for promoting energy transformation and/or nurturing environmental cultures associated with environmental education improvement in Vietnam and beyond.
