Troy Townsend's thesis explores the structure, energetics and activity of three inorganic nanocrystal photocatalysts. The goal of this work is to investigate the potential of metal oxide nanocrystals for application in photocatalytic water splitting, which could one day provide us with clean hydrogen fuel derived from water and solar energy. Specifically, Townsend's work addresses the effects of co-catalyst addition to niobium oxide nanotubes for photocatalytic water reduction to hydrogen, and the first use of iron oxide 'rust' in nanocrystal suspensions for oxygen production. In addition, Townsend studies a nickel/oxide-strontium titanate nanocomposite which can be described as one of only four nanoscale water splitting photocatalysts. He also examines the charge transport for this system. Overall, this collection of studies brings relevance to the design of inorganic nanomaterials for photocatalytic water splitting while introducing new directions for solar energy conversion.

This book focuses primarily on the advantages and implications of sustainable bioenergy production in terms of ensuring a more sustainable world despite its growing energy demands. It addresses a new concept that focuses on the interactions between different uses of agricultural land (for example, agriculture for food, forage or energy and nature conservation) and their ecological, economic and societal impacts. This research concept provides new insights into the competition for resources and the synergies between different land uses. This book seeks to improve people's understanding of bioenergy's potentials for the future. It will be of interest not only to those involved in sustainable energy, but also to environmental planners, agriculture and soil specialists, and environmental policy-makers.

As the re-emergence of nuclear power as an acceptable energy source on an international basis continues, the need for safe and reliable ways to dispose of radioactive waste becomes ever more critical. The ultimate goal for designing a predisposal waste-management system depends on producing waste containers suitable for storage, transportation and permanent disposal. "Cement-Based Materials for Nuclear-Waste Storage "provides a roadmap for the use of cementation as an applied technique for the treatment of low- and intermediate-level radioactive wastes. Coverage includes, but is not limited to, a comparison of cementation with other solidification techniques, advantages of calcium-silicate cements over other materials and a discussion of the long-term suitability and safety of waste packages as well as cement barriers.

Renewable energy sources such as wind power have attracted much attention because they are environmentally friendly, do not produce carbon dioxide and other emitants, and can enhance a nation's energy security. For example, recently more significant amounts of wind power are being integrated into conventional power grids. Therefore, it is necessary to address various important and challenging issues related to wind power systems, which are significantly different from the traditional generation systems. This book is a resource for engineers, practitioners, and decision-makers interested in studying or using the power of computational intelligence based algorithms in handling various important problems in wind power systems at the levels of power generation, transmission, and distribution. Researchers have been developing biologically-inspired algorithms in a wide variety of complex large-scale engineering domains. Distinguished from the traditional analytical methods, the new methods usually accomplish the task through their computationally efficient mechanisms. Computational intelligence methods such as evolutionary computation, neural networks, and fuzzy systems have attracted much attention in electric power systems. Meanwhile, modern electric power systems are becoming more and more complex in order to meet the growing electricity market. In particular, the grid complexity is continuously enhanced by the integration of intermittent wind power as well as the current restructuring efforts in electricity industry. Quite often, the traditional analytical methods become less efficient or even unable to handle this increased complexity. As a result, it is natural to apply computational intelligence as a powerful tool to deal with various important and pressing problems in the current wind power systems. This book presents the state-of-the-art development in the field of computational intelligence applied to wind power systems by reviewing the most up-to-date work and representative practical problems collecting contributions from leading experts in electrical engineering, system engineering, and other disciplines.

Increasing interest in geo-environmental problems, including chemical coupling, marks new perspectives in unsaturated soil mechanics. This book will provide a valuable up-to-date reference across the subject for both researchers and practitioners.

The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40-50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40-50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.

What lies beyond the era of fossil fuels? While most answers focus on different primary energy resources, "Energy Systems in the Era of Energy Vectors" provides a completely new approach.

Instead of providing a traditional consumption analysis of classical primary energy resources such as oil, coal, nuclear power and gas, "Energy Systems in the Era of Energy Vectors" describes and assesses energy technologies, markets and future strategies, focusing on their capacity to produce, exchange, and use energy vectors. Special attention is given to the renewable energy resources available in different areas of the world and made exploitable by the integration of energy vectors in the global energy system.

Clear definitions of energy vectors and energy systems are used as the basis for a complete explanation and assessment of up-to-date, available technologies for energy resources, transport and storage systems, conversion and use. The energy vectors scheme allows the potential realization of a worldwide sustainable energy system to fulfill global development expectations by minimizing both the impact on the environment, and the international political frictions for access to limited and concentrated resources.

"Energy Systems in the Era of Energy Vectors" is an informative read for researchers and advanced students in industrial, energy and environmental engineering. It also contains valuable information for managers and technicians working in the energy sector.

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.

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. .
