Chapter 7 begins to reimagine energy security. It returns to the bigger question of what energy security can and should mean, relating the empirical discussion back to the broader context and discussion of what it means to be secure in the contemporary world. It draws together the range of notions of energy security presented in the previous four chapters, and relates these to the debate over the value of security, to theorize the value of energy security based on the analysis undertaken. The book ends by using this to consider how we might reimagine energy security. It explores how change could come about and what it would need to look like, considering both the possibilities for, and the obstacles to, change.
