The European Union (EU) has set out ambitious targets to address European sustainability and environmental challenges. As part of this, policies and initiatives focusing on both energy supply and energy demand have been established. Yet, the complexity of enacting the required actions demonstrates the need for interdisciplinary collaboration to inform approaches. The integration of Social Sciences and Humanities (SSH) and the technical sciences (Science, Technology, Engineering and Mathematics (STEM)) provides opportunities to identify policy approaches which challenge the status quo, supporting low-carbon energy transitions. This book includes interdisciplinary recommendations for relevant EU energy strategies—a total of 10 recommendations, split into four parts, are presented. This chapter includes a breakdown of the book’s chapters and its overall narrative. The chapter closes with tips on how to read the book as a whole, as well as the individual chapters it is composed of.
