Emergy

Emergy presents the fundamentals of emergy, proposing the definition and representation of emergy diagrams and 'spreading.' Embodied energy is the energy consumed by all of the processes associated with the production of a building, from the mining and processing of natural resources to manufacturing, transport and product delivery. The authors evaluate a range of sources and the methodologies surrounding emergy analysis. Filled with real-world applied examples including wood energy, wind resources, ore and recycling, this book shows you how to adopt an approach similar to the Lagrangian approach to fluid mechanics, and establish that the intuitive notion of temporal independence of the emergy specific to materials requires nuances. Presents the fundamentals of emergy, its original definition, and methodology Evaluates a range of different sources such as wood energy, wind, recycling, and ore Provides real-world application examples in connection with the climate energy plan of H2020 by the European Union Introduces enhanced emergy concepts

This book builds on the analyses of Eugene and Howard Odum and introduces the concept of systems ecology. Ecological emergy accounting represents a breakthrough because it allows researchers to integrate man-made capital and natural capital so that human and natural concerns can be addressed using a consistent system of units. This book develops an emergy accounting model that is suitable for describing urban systems, thereby providing a comprehensive picture of those systems. To make the theory concrete, the authors use China’s Macao Special Administrative Region as a case study, and compare the results for Macao with those of other urban ecosystems around the world in the fields of ecological economy, tourism, waste treatment, gambling industry, land reclamation and resource consumption etc. Dr. Kampeng Lei is an advisory senior technician at the Environmental Protection Bureau, Government of Macao, China; Shaoqi Zhou is a professor at the College of Environment and Energy, the South China University of Technology, and the Guizhou Academy of Sciences, China; Zhishi Wang is a professor at the Faculty of Science and Technology, the University of Macau, China.
