In a time of economic crisis the need to adopt energy conservation practices comes to the fore. It is helpful to evaluate the role of young people as both consumers and potential agents of change bridging the gap between school and family to encourage lower household energy consumption. Based on two surveys of parents and students of a secondary school in Lisbon, plus in-depth interviews with parents, this article analyzes the complexity of this challenge, highlighting adults' perceptions of their children's contribution to energy saving. Results show that parents see young people as major energy consumers. Young people's engagement with electronic equipment as essential components of their lifestyles and their belief in technology as a solution to energy problems thwart them from being promoters of energy saving. In this context of scarcity, parents try to protect their children's well-being and opportunities in life by accepting their children's unrestricted energy use.
