Reinforcing the utility of the concept of energy literacy, this research indicates that knowledge and attitudinal variables are both important contributors to the development of effective energy-saving behaviours. Despite the commonly cited claim that knowledge alone does not engender more sustainable behaviours, it is clearly a contributor to effective behaviour change in this particular context. Anable et al. (2006) identify a set of different types of knowledge they regard as necessary to prompt behavioural modification in relation to climate change. Among the most significant of these is knowledge of: the facts of the issue; the causes and effects of the issue; its urgency and importance; and the contribution of individual behaviour. Based on our research, we would add to this list “knowledge of the impact of behavioural changes” – as it was clear that students were not well enough informed about basic principles of energy to make rational behavioural choices, even where they possessed knowledge of energy issues at a general level.
