Book Description
Our consumption of raw materials and energy has reached unprecedented levels which are continuing to increase at a steady rate due to the economic emergence of many countries and the development of new technologies. Metal and cement usage has doubled since the beginning of the 21st Century and this production, between now and 2050, will be equivalent to that produced since the beginning of humanity. It is in this context that the transition to low-carbon and renewable energies is taking place, which involves profound changes to the existing global energy system. This book addresses these different aspects and attempts to estimate first-order requirements for cement, steel, copper, aluminum and energy for different power generation technologies, and for three types of energy scenarios. Some dynamic modeling approaches are proposed to assess the needs and likely evolution of primary production and recycling. The link between production and primary reserves, recycling and stocks of end-of-life products, production costs, incomes and prices using a prey–predator dynamic is discussed. - Approaches the issues of commodities and energy in terms of needs, technological innovation and economic and social issues - Emphasizes the couplings between these different aspects - Helps readers understand and integrate these couplings through global modeling

Book Description
Hierarchy is a form of organisation of complex systems that rely on or produce a strong differentiation in capacity (power and size) between the parts of the system. It is frequently observed within the natural living world as well as in social institutions. According to the authors, hierarchy results from random processes, follows an intentional design, or is the result of the organisation which ensures an optimal circulation of energy for information. This book reviews ancient and modern representations and explanations of hierarchies, and compares their relevance in a variety of fields, such as language, societies, cities, and living species. It throws light on concepts and models such as scaling laws, fractals and self-organisation that are fundamental in the dynamics and morphology of complex systems. At a time when networks are celebrated for their efficiency, flexibility and better social acceptance, much can be learned about the persistent universality and adaptability of hierarchies, and from the analogies and differences between biological and social organisation and processes. This book addresses a wide audience of biologists and social scientists, as well as managers and executives in a variety of institutions.

Book Description
This 2010 edition of Energy Technology Perspectives examines the extent to which an energy technology revolution is taking place, the key technologies that are emerging, the costs and benefits of these technologies, and policies needed to foster their use. ETP 2010 presents updated scenarios from the present to 2050 that show which new technologies will be most important in key sectors and in different regions of the world. It highlights the importance of finance to achieve change, examines the implications of the scenarios for energy security and looks at how to accelerate the deployment of low-carbon technologies in major developing countries. It presents roadmaps and transition pathways for spurring deployment of the most important clean technologies and for overcoming existing barriers. With extensive data, projections and analysis, Energy Technology Perspectives 2010 provides decision makers with the detailed information and insights needed to accelerate the switch to a more secure, low-carbon energy future.

Book Description
The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Book Description
This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.

Book Description
Economics of Natural Resources and the Environment brings together the approaches of natural resource economics and environmental economics to provide a comprhensive overview of the economics of national international and global environmental problems. A unifying theme throuhhout the book is the concept of "sustainable development" defined as "maximizing the net benefits of economic development while maintaining the services and quality of natural resources over time." The authors emphasize the continuing importance of a mainstream approach. They stress "economic efficiency—getting the most welfare out of a given endowment of resources." And they address the larger moral issues as well. Chapter topics include the historical development of environmental economics, environmental ethics, and pollution control policy in "free" mixed market and centrally planned economies. Other current issues seen from an economic perspective include destruction of the ozone layer, the greenhouse effect, policy weapons in the fight against pollution, and the special problems of the third world. Economics of Natural Resources and the Environment offers a thorough review and synthesis of the major work of the field's senior scholars. It will be of value not only to students of natural resource economics, environmental economics, geography, and environmental sciences but also to all with an interest in economic appraoches to environmental issues.
