This book delineates the analytical frameworks and methodologies relevant to the study of energy transition pathways, reviews the latest dynamics within the global energy sector, and provides a comprehensive examination of the developmental trends and potential of various energy sources. It places particular emphasis on medium- and long-term scenario analyses regarding global and regional energy development, while also identifying emerging areas that merit attention in the context of energy transition and the holistic benefits associated with achieving such transitions. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
