This book is an exploration of energy and its unique role to date as one of the fundamental enabling and controlling factors in human development and progress at the scale of global civilization, and how it will be fundamental to the type of future that collective humanity is likely to experience. The first section provides a contextual overview of energy and human civilization through a chronological description of how human energy use has evolved over time and led to the current energy bind. The second section explores what this energy bind might mean for our future energy choices when trying to meet the various challenges of dwindling resources, costs, and climate change, through exploration of three broad systems-based scenarios for the human energy future.  The final section draws conclusions as to which scenario is most achievable and desirable, and what this might mean for longer-term human prospects.
