Energy literacy can empower individuals to make informed decisions about energy use. However, the level of public interest in learning about energy-related topics remains uncertain, and there is a dearth of research exploring energy literacy-related knowledge gaps. This mixed-methods study aimed to address those issues. A survey of 3,843 citizens from four European countries revealed that most citizens have only a moderate interest in learning about energy. Age, gender, educational level, income level, living situation and environmental attitudes appear to have a significant effect on individuals’ interests. The study identified key knowledge demand areas regarding saving energy and reducing costs, becoming self-sufficient in energy production and cooperating with others for more efficient energy use. The findings indicate that engagement with energy-related topics could be improved by considering affective factors such as individual interest. The study also reveals a need for greater interdisciplinarity in energy research.

As countries develop, they are likely to face challenges in meeting growing energy demand and in ensuring energy security. Given this, and the problem of climate change, improving demand-side energy efficiency is pivotal to ensuring sustainable development. However, agents often underinvest in energy-efficient technologies due to behavioral failures such as low levels of energy-related financial literacy, defined as the combination of energy knowledge and cognitive abilities needed to evaluate the lifetime costs of durables. Using novel data, we analyze the levels and determinants of energy-related financial literacy of households in urban areas in the eastern lowlands of Nepal, and whether it is correlated with their attitudes towards replacement of energy-inefficient appliances. We find that respondents have low levels of energy-related financial literacy, and higher levels of literacy are associated with more rational attitudes towards appliance replacement. The findings of this study are relevant to addressing the energy-efficiency gap in developing countries.
