Topics have been selected to highlight both the variety of raw materials treated in biorefineries and the range of biofuel and chemical end-products.
This book provides an outstanding single-volume resource on the topic of solar energy for young adults and general audiences. While how much longer the world's supply of fossil fuels will last is debatable, it is a fact that the fossil fuels that we depend on so heavily today are non-renewable resources that will inevitably be exhausted-making the need to shift to alternative sources of energy such as solar extremely important. Solar Energy: A Reference Handbook presents encyclopedic coverage of the social, political, economic, and environmental issues associated with the development and use of solar energy in the United States and around the world. This book provides an in-depth description of the ways solar power has been used for at least 2,000 years. It outlines how humankind has utilized various forms of energy from the sun by way of photovoltaic cells, concentrating or focusing solar power, active and passive solar heating, and other mechanisms; and provides perspectives on today's solar energy issues from a variety of subject experts. Readers will better understand not only the advantages and disadvantages of solar power but also the critical nature of energy production to sustaining life on earth, thereby underscoring the importance of developing solar power and other alternative sources of energy to meet the world's energy needs in coming decades. The book also includes profiles of key individuals and organizations related to the field of solar energy, a chronology of important events in the history of solar energy, and a glossary that defines the key terms used in discussing the topic of solar energy. Provides an accessible and useful technical introduction to the various ways in which solar energy can be used for heat production and the generation of electricity Outlines some of the critical environmental, technical, economic, and political issues that have prevented solar energy from becoming a more significant part of the nation's energy equation Includes primary source documents such as relevant laws, court cases, position statements, and other items that allow readers to directly examine the history of solar energy
Cement production is known to be a polluting and energy-intensive industry. Cement plants account for 5 percent of global emissions of carbon dioxide and one of the main causes of global warming. However, cement it is literally the glue of progress. Designing Green Cement Plants provides the tools and techniques for designing new large cement plants that would promote sustainable growth, preserve natural resources to the maximum possible extent and make least possible additions to the Greenhouse Gases that cause global warming. Brief and but authoritative, this title embraces new technologies and methods such as Carbon Capture and Sequestration, as well as methods for harnessing renewable energy sources such as wind and solar. The author also discusses the efficient use of energy and materials through the use recycling. In addition, this book also examines thepossibilities of developing green cement substitutes such as Calera, Caliix, Novacem, Aether and Geopolymer cements.
Towards Nearly Zero Energy: Urban Settings in the Mediterranean Climate discusses tactics that can be used to effectively reduce energy consumption towards zero energy. With energy usage in buildings accounting for over 40% of primary energy use and 24% of greenhouse gas emissions worldwide, this remains an unavoidable objective. The book looks at the life of the systems of energy production from renewable sources amidst the exceptionally challenging global economic crisis that the Mediterranean areas and other societies are currently experiencing. By using an innovative and interdisciplinary approach of socio-oriented technological design, the book indicates tools and measures that can be developed at the public, legislative, and market levels to counterbalance the large pay-back times of energy efficiency measures. In particular, the book displays guidelines and best practices to activate new forms of economic incentives in order to attract potential investors that demonstrate that a large set of possible solutions is technically feasible to achieve nearly zero energy, even in high energy consuming circumstances and urban settings. Furthermore, by discussing and comparing the economic and energy impact of different technology options, this work offers guidelines and best practices to activate new cost-effective forms and social incentives in order to attract both potential investors and motivate the urban stakeholders toward nearly zero energy.
Groundwater contributes to the sustainable development of many Asian cities by providing water for domestic, industrial and agricultural uses and regulating ecosystem flows. However, groundwater has not always been properly managed, which often has resulted in depletion and degradation of the resource. Groundwater Environment in Asian Cities presents the up-to-date scientific knowledge on groundwater environment in fourteen Asian cities using Driver-Pressure-State-Impact-Response (DPSIR) framework. In detail the book presents the facts and figures of groundwater dependency, problems related to groundwater over exploitation, implementation of various policy instruments and management practices and their results in selected fourteen Asian cities, namely; Bandung (Indonesia), Bangkok (Thailand), Beijing (China), Bishkek (Kyrgyzstan), Chitwan (Nepal), Delhi (India), Dili (East Timor), Ho Chi Minh (Vietnam), Hyderabad (India), Khulna (Bangladesh), Lahore (Pakistan), Seoul (South Korea), Tokyo (Japan), and Yangon (Myanmar). The book provides the one-step platform to get sufficient details about groundwater aquifers, hydrogeology, groundwater status, impacts on groundwater environment and responses (technology, policy, institutional, etc.) deployed in the case studies cities, and therefore, provides a snap-shot of Asian groundwater environments. The theoretical background of the topics discussed along with the case studies help the readers understand the similarities and differences about the status of groundwater development and use in each city. In addition, the information in the book will serve as a baseline for other research such as mitigation of groundwater related problems (e.g., land subsidence), impact of climate change on groundwater, and importance of groundwater for implementing sustainable development goals in future.
Today's highly industrialized and technologically controlled global food systems dominate our lives, shaping our access and attitudes towards food and deeply influencing and defining our identities. At the same time, these food systems are profoundly and destructively impacting the health of the environment and threatening all of us, human and nonhuman, who must subsist in ecological conditions of increasing fragility and scarcity. This collection examines and exposes the myriad ways that the food systems, driven by global commodity capitalism and its imperative of growth at any cost, increasingly controls us and conforms us to our roles as consumers and producers. This collection covers a range of topics from the excess of consumers in the post-industrial world and the often unacknowledged yet intrinsic connection of their consumption to the growing ecological and health crises in developing nations, to topics of surveillance and control of human and nonhuman bodies through food, to the deep linkages of cultural values and norms toward food to the myriad crises we face on a global scale.
This book addresses environmental changes and how they reconfigure society's relationship to the future. It argues that Man does not build "his" future alone: instead, environmental changes are also proof of the future-making capacity of non-human beings. The author elaborates on the notion of the futures of Nature by drawing on theoretical contributions by recent ground-breaking literature in the field of environmental humanities. The book also builds on a sociological investigation into the practices implemented by environmental scientists, experts and managers confronted with environmental changes. Thinking of nature in terms of its futures requires us to overcome the rooted philosophical tradition that associates nature with permanence and society with creative change. This is a daunting task which can only be successful if we look beyond the long-lasting influence of the human-centered categories of innovation, development and civilization that social sciences have themselves contributed to coining. We need to consider the active capacities of change and transformation of living beings and matter itself. This book is of academic interest, but is also for managers in different fields and areas affected by environmental changes.
The world’s economy is fuelled by energy. Depletion of resources and severe environmental effects resulting from the continuous use of fossil fuels has motivated an increasing amount of interest in renewable energy resources and the search for sustainable energy policies. This volume contains research papers presented at the 9th International conference on Energy and Sustainability. The changes required to progress from an economy mainly focussed on hydrocarbons to one taking advantage of sustainable renewable energy resources require considerable scientific research, as well as the development of new engineering systems. Energy policies and management are of primary importance to achieve the development of sustainability and need to be consistent with recent advances in energy production and distribution. In many cases, the challenges lie as much in the conversion from renewable energies (wind, solar, etc.) to useful forms (electricity, heat, fuel) at an acceptable cost including damage to the environment as in the integration of these resources into the existing infrastructure. The diverse topics covered by the papers in this book involve collaboration between different disciplines in order to arrive at optimum solutions, including studies of materials, energy networks, new energy resources, storage solutions, waste to energy systems, smart grids and many others. These research papers put a focus on sustainability across the multidisciplinary components of urban planning, the challenges presented by the increasing size of cities, the number of resources required and the complexity of modern society.
Physics and the Environment directly connects the physical world to environmental issues that the world is facing today and will face in the future. It shows how the first and second laws of thermodynamics limit the efficiencies of fossil fuel energy conversions to less than 100%, while also discussing how clever technologies can enhance overall performance. It also extensively discusses renewable forms of energy, their physical constraints and how we must use science and engineering as tools to solve problems instead of opinion and politics. Dr. Kyle Forinash takes you on a journey of understanding our mature and well developed technologies for using fossil fuel resources and how we are unlikely to see huge gains in their efficiency as well as why their role in climate change ought to be an argument for their replacement sooner rather than later. He also discusses the newest technologies in employing renewable resources and how it is important to understand their physical constrains in order to make a smooth transition to them. An entire chapter is dedicated to energy storage, a core question in renewable energy as well as another chapter on the technical issues of nuclear energy. The book ends with a discussion on how no environmental solution, no matter how clever from a technical aspect, will succeed if there are cheaper alternative, even if those alternatives have undesirable features associated with them.

NB: Due to the inadvertent assignment of a previously used ISBN, this book was originally published under an incorrect identifying number. The book has now been given its own unique ISBN and is otherwise identical in every way to the original publication. Feeding Everyone No Matter What presents a scientific approach to the practicalities of planning for long-term interruption to food production. The primary historic solution developed over the last several decades is increased food storage. However, storing up enough food to feed everyone would take a significant amount of time and would increase the price of food, killing additional people due to inadequate global access to affordable food. Humanity is far from doomed, however, in these situations - there are solutions. This book provides an order of magnitude technical analysis comparing caloric requirements of all humans for five years with conversion of existing vegetation and fossil fuels to edible food. It presents mechanisms for global-scale conversion including: natural gas-digesting bacteria, extracting food from leaves, and conversion of fiber by enzymes, mushroom or bacteria growth, or a two-step process involving partial decomposition of fiber by fungi and/or bacteria and feeding them to animals such as beetles, ruminants (cows, deer, etc), rats and chickens. It includes an analysis to determine the ramp rates for each option and the results show that careful planning and global cooperation could ensure the bulk of humanity and biodiversity could be maintained in even in the most extreme circumstances.

Recent major earthquakes, tsunamis, hurricanes, floods and other natural phenomena have resulted in huge losses in terms of human life and property destruction. A new range of human-made disasters have afflicted humanity in modern times; terrorist activities have been added to more classical disasters such as those due to the failure of industrial installations. It is important to understand the nature of these global risks to be able to develop strategies to prepare for these events and plan effective responses in terms of disaster management and the associated human health impacts. The selected papers contained in this book have been written by academics and professionals and represent some of the latest developments in the field.
A major theme of this book is that, contrary to what many experts believe, being endowed with a plenitude of natural resources is not a curse: rather it provides a potential advantage, if capitalized by the well-endowed economy. Much depends on the institutions that help frame the decision-making process that affects the process of growth and development. Canada is an example of a successful export-oriented economy. And, its export-orientation has been a focal point of discussion and debate, going way back to discussions of the early fur trade, the fishing industry, wheat farming, and mining and oil and gas exploration. Unlike other economies well-endowed with natural resources, Canada does not appear to be at all cursed, but rather blessed with natural resource abundance. This book, which ranges from the late seventeenth to the early twentieth century, provides insights from Canadian economic history on how such abundance can be a handmaiden of successful growth and development. From this perspective, the natural resource curse appears to be more of a 'man-made' phenomenon than anything else. This book also investigates aspects of gender inequality in Canada as well as the evolution of hours worked as it intersects with worker preferences and 'market forces'. The narratives in this book are contextualised by the construction of new or significantly revised data sets, which speaks to the importance of data construction to robust economic analysis and economic history.
