Differing interpretations, perspectives and expectations on the term sustainability exist. To take sustainability as an action guiding mandate for implementation it needs to be concrete and measurable as well it should weigh pros and cons. But how can such an integrated measurement in the field of renewable energy be conducted balancing the trade-offs between opposing indicators? Glances at Renewable and Sustainable Energy provides a thorough overview on the generic principles of sustainability assessment, including projective, thresholding and systemic principles and summarizes five common approaches for a holistic measurement. Approaches such as multi criteria decision analysis, ecological footprint analysis and normative-functional concepts are applied to different case studies in developed-, emerging and developing countries to cover a wide bandwidth of various renewable energy carriers under various conditions. Each case study includes 2 boxes illustrating the scheme behind the approach and exemplary calculations to allow a systematic comparison and a critical reflection of the methods applied. Compiling results on renewable energy assessment of the last decades, Glances at Renewable and Sustainable Energy gives researchers, students, consultants, politicians and entrepreneurs the tools to advance their oriental and instructional knowledge on sustainability and sustainability measurement, to reflect their decisions and tools for analysis and to transfer this knowledge into problem-solving.

Second-Generation High-Temperature Superconducting Coils and Their Applications for Energy Storage addresses the practical electric power applications of high-temperature superconductors. It validates the concept of a prototype energy storage system using newly available 2G HTS conductors by investigating the process of building a complete system from the initial design to the final experiment. It begins with a clear introduction of the related background and then presents a comprehensive design of a superconducting energy storage system that can store maximum energy using a limited length of superconductors. The author has created a modeling environment for analysis of the system and also presents experimental results that are highly consistent with his theoretical calculations.

Biofuels have been represented by some as a silver bullet to the climate change threat, and by others as a fatal mistake set to destroy forests and increase hunger; they are neither. Sane and sensibly developed they offer a chance to reduce emissions, generate employment and diversify rural livelihoods. But widespread commercialisation without proper sustainability standards could prove a disaster, causing more environmental and human harm than good. This new WBGU report shows that a sustainable use of bioenergy is possible and outlines how opportunities can be exploited while at the same time minimizing risks. This large and detailed report examines the issues surrounding bioenergy from a global perspective and demonstrates how the sustainable use of bioenergy can help minimize risks to food security, nature conservation and climate change. .

With the resurgence of nuclear power around the world, and the increasingly important role of hydrogen as a clean energy carrier, the utilization of nuclear energy for large-scale hydrogen production will have a key role in a sustainable energy future.

This book includes an in-depth analysis of the environmental and energy security impacts of replacing the internal combustion engine vehicle with various forms of electric vehicles and replacing gasoline and diesel fuel with alternative fuels including electricity, hydrogen and biofuels. In addition to a detailed "well-to-wheels" analysis of local air pollution, greenhouse gas emissions and oil consumption for each alternative vehicle, the book estimates the market penetration potential of each fuel/vehicle combination to determine the most likely societal impact of each alternative vehicle pathway. To support the market penetration estimates, the book analyses the likely cost of each alternative vehicle in mass production and the cost of installing the necessary fuel infrastructure to support each option. The book provides sufficient detail to allow decision makers in governments and industry to choose among the alternative vehicle/fuel combinations that will lead to a truly sustainable transportation system.

This book provides an analysis of the reaction mechanisms relevant to a number of processes in which CO2 is converted into valuable products. Several different processes are considered that convert CO2 either in specialty chemicals or in bulk products or fuels. For each reaction, the mechanism is discussed and the assessed steps besides the dark sites of the reaction pathway are highlighted. From the insertion of CO2 into E-X bonds to the reduction of CO2 to CO or other C1 molecules or else to C2 or Cn molecules, the reactions are analysed in order to highlight the known and obscure reaction steps. Besides well known reaction mechanisms and energy profiles, several lesser known situations are discussed. Advancing knowledge of the latter would help to develop efficient routes for the conversion of CO2 into valuable products useful either in the chemical or in the energy industry. The content of this book is quite different from other books reporting the use of CO2. On account of its clear presentation, "Reaction Mechanisms in Carbon Dioxide Conversion" targets in particular researchers, teachers and PhD students.

The recommendations summarise the state of the art. Their aim is the proper exploitation of the ground for geothermal purposes without adversely affecting the ground or the groundwater on the one hand and the operation of the system and nearby buildings on the other. The recommendations should be used during consulting, design, installation and operation in order to achieve optimum and sustainable use of the ground at a specific location. Authorities responsible for supervising and approving projects can use the recommendations as a guide when taking decisions and making stipulations. The Geothermal Energy Study Group was set up in Bochum in 2004 and became the joint DGGV/DGGT study group in 2007. Some 20 specialists from universities, authorities and engineering consultants are active in the group and meet two or three times a year.

Energy security, rising energy prices (oil, gas, electricity), 'peak oil', environmental pollution, nuclear energy, climate change and sustainable living are hot topics across the globe. Meanwhile, abundant and perpetual wind resources offer opportunities, via recent technological developments, to provide part of the solution to address these key issues. The rapid growth of large-scale wind farm installations has now led to the generation of clean electricity for tens of millions of homes around the world. However, despite the potential to reduce the losses and costs associated with transmission and to use local wind acceleration techniques to improve energy yields, the potential for urban wind energy has yet to be realised. Although there is increasing public interest, the uptake of urban wind energy in suitable areas has been slow. This is in part due to a lack of understanding of key issues such as: available wind resources; technology integration; planning processes (include assessment of environmental impacts and public safety due to close proximity to people and property); energy consumption in buildings versus energy production from turbines; economics (including grants, subsidies, maintenance); and the effect of complex urban windscapes on performance. Urban Wind Energy attempts to illuminate these areas, addressing common concerns highlighting pitfalls, offering real world examples and providing a framework to assess viability in energy, environmental and economic terms. It is a comprehensive guide to urban wind energy for architects, engineers, planners, developers, investors, policy-makers, manufacturers and students as well as community organisations and home-owners interested in generating their own clean electricity.

This book presents a Two-Stage Anaerobic Digestion (TSAD) technique for producing hydrogen and methane, following a step-by-step approach in order to guide readers through the experimental verification of the related hypothesis. In the first stage of AD, the reaction conditions are optimized to obtain the maximum amount of hydrogen, while in the second the liquid residue from the first phase is used as a substrate to produce fuel-methane. AD has traditionally been used to reduce the organic content of waste; this results in a biogas that is primarily constituted of CH4 and CO2. Over the last few decades, the conversion of organic matter into hydrogen by means of AD and selecting Hydrogen Producing Bacteria (HPB) has matured into a viable and sustainable technology among the pallet of H2 generation technologies. The combined bio-production of hydrogen and methane from Organic Waste Materials (OWM) is considered to be an ideal way of utilizing waste, and can increase energy efficiency (the substrate Heat Value converted into H2 and CH4 fuel) to roughly 80%, since the energy efficiency of H2-production alone (15%) is not energetically competitive. The two gas streams can be used either separately or in combination (Hytane (R)), be supplied as civilian gas or used for transportation purposes. All the aspects of this sustainable technology are taken into account, from the basic biochemical implications to engineering aspects, establishing the design criteria and the scale-up procedures for full-scale application. The sustainability of the TSAD method is assessed by applying EROI (Energy Return On Investment) and EPT (Energy Payback Time) criteria, and both the general approach and application to the field of Anaerobic Digestion are illustrated.

The liberalization of U.S. and European electric power markets presents a critical challenge for renewable sources of energy. Edinger and Kaul survey the technological state-of-the-art and economic aspects of renewable electricity generation, and outline the role of other renewable sources, such as solar, wind, and micro-hydroelectric technologies. Offering an empirical and theoretical assessment of these technologies and their assets and liabilities, the book shows how it is possible to restructure our electric power systems and reorient them toward sustainable and environmentally friendly alternatives.

International climate conferences such as those in Rio de Janeiro and Kyoto have proclaimed the need for environmentally hospitable technologies. A new electricity system, based on renewable resources and small-scale power technologies, is needed badly; their economics and other efficiencies over conventional central power generation with fossil fuels is clear. Edinger and Kaul assess the rewards and risks associated with renewable technologies and outline a feasible path toward a more environmentally friendly, and reasonable, use of limited natural resources and the global ecosystem. One promising approach for industrialized countries is the decentralization of our current public grid systems. This offers an opportunity for developing countries to leapfrog the stage of fossil fuel, held responsible now for environmental pollution, resource depletion and possibly global climate change. The authors present theoretical analyses and empirical evidence to buttress their contentions, mainly, that electric power systems founded on renewable resources are vital prerequisites if we are to achieve the United Nations' target of globally sustained development.
