Renewable energy is a fast-expanding field, welcomed by many as part of the answer to climate change and energy security concerns; but can renewables deliver enough energy reliably and economically? Rapid expansion continues in the area of renewable energy, with wind capacity expected to double over the next five years and PV solar perhaps treble in the same period. There have been some dramatic projections of potential expansion longer term, with some studies now suggesting that renewables could supply all, or nearly all, electricity needs globally and perhaps also all energy needs by 2050. In this book, David Elliott conveys the sense of excitement that abounds in this new area of technological development not only reviewing the basic technological options and how renewable technologies are being implemented and used around the world, but also considers the problems, including local environmental impacts and the need to deal with the variability of some renewable energy sources. Dividing the renewable energy supply options into those based on mechanical power, heat and light it also looks at some related energy-conversion options, including fuel cells, heat pumps and cogeneration/combined heat and power. The author explores how these new sources can be integrated and used together with technologies for reducing energy waste and demand to replace conventional energy sources and ensure a balance of supply and demand. After reviewing the renewable energy options, the book then considers implementation and policy issues, including storage and grid balancing; aspects that will play a critical role in the creation of sustainable, clean and viable renewable energy solutions. This is not a textbook – there are plenty available – instead the book reviews what is happening across this field at this time of great change and rapid development. Supplemented with many case studies and links to information sources, this book will be essential reading for scientists, engineers, policymakers and anybody involved with, or interested in, the implementation of green and renewable energy technologies, and the environmental aspects of modern energy demands.

This book provides a state-of-the-art perspective on industrial biorenewables. A selection of industries dealing with biomass as raw materials present their activities and industrial processes. Emphasis on each chapter includes, and is not limited to: discussion of the motivation of that specific industry to use biorenewables; a short history of their expertise and developments in the field; selected current R&D activities using biomass, the aim of the research, type of biomass used, catalysts, achieved products, economics, etc.; detailed discussions of the type of biomass, indicating 1st or 2nd generation, and options to substitute 1st generation raw materials for more sustainable 2nd generation ones; current processes that have been or are about to be implemented at industrial and commercial scales; expectations such as where potential improvements could be made and where academic research groups could help provide pre-competitive and industrially-sound insights and research; and finally, conclusions, prospects, and recommendations for future directions of research.

Over the past decade, renewables-based technology and sustainability assessment methods have grown tremendously. Renewable energy and products have a significant role in the market today, and the same time sustainability assessment methods have advanced, with a growing standardization of environmental sustainability metrics and consideration of social issues as part of the assessment. Sustainability Assessment of Renewables-Based Products: Methods and Case Studies is an extensive update and sequel to the 2006 title Renewables-Based Technology: Sustainability Assessment. It discusses the impressive evolution and role renewables have taken in our modern society, highlighting the importance of sustainability principles in the design phase of renewable-based technologies, and presenting a wide range of sustainability assessment methods suitable for renewables-based technologies, together with case studies to demonstrate their applications. This book is a valuable resource for academics, businesses and policy makers who are active in contributing to more sustainable production and consumption.

Sustainability is a key driving force for industries in the chemical, food, packaging, agricultural and pharmaceutical sectors, and quantitative sustainability indicators are being incorporated into company reports. This is driving the uptake of renewable resources and the adoption of renewables. Renewables' can either be the substituted raw materials that are used in a given industry, (e.g. the use of biomass for fuel); the use and/or modification of a crop for use in a new industry (e.g. plant cellulose), or the reuse of a waste product (e.g. organic waste for energy production). This is the first book in the Wiley Renewable Resources series that brings together the range of sustainability assessment methods and their uses. Ensuing books in the series will look at individual renewable materials and applications.

With its focus on catalysis and addressing two very hot and timely topics with significant implications for our future lives, this will be a white book in the field. The authority behind this practical work is the IDECAT Network of Excellence, and the authors here outline how the use of catalysis will promote the more extensive use of renewable feedstocks in chemical and energy production. They present the latest applications, their applicability and results, making this a ready reference for researchers and engineers working in catalysis, chemistry, and industrial processes wishing to analyze options, outlooks and opportunities in the field.

Renewable energy (RE) is a subject of great interest today. It is one of the two main means for implementing climate change mitigation programmes, and presently the only perceived means for replacing the declining global fossil fuel reserves. It also helps fight poverty and assists in the global quest for gender equity by taking clean energy where it is needed most for development. It is perhaps not surprising therefore that there is so much coverage of RE in both the conventional media and the internet by media and tech writers, economists and bloggers, many of who only have a partial understanding of the technology itself. The end result is mostly promotional rhetoric that says little about the true value of the technology, and leads to a confused picture for the serious individual or decision-maker who wants to know what the technology is really capable of doing. This book provides a clear and factual picture of the status of RE and its capabilities today. The need for such a book was first realized by the author when he was engaged in a renewable energy capacity-building project encompassing countries from Europe, the Caribbean, Africa, and the Pacific. The book is largely non-technical in nature; it does however contain enough mention of the science and technology to enable readers to go further with their own investigations should they wish to. The book covers all areas of renewable energy (RE), starting from biomass energy and hydropower and proceeding to wind, solar and geothermal energy before ending with an overview of ocean energy. It begins with a simple introduction to the physical principles of the RE technologies, followed by an enumeration of the requirements for their successful implementation. The last two chapters consider how the technologies are actually being implemented today and their roles in climate change mitigation and poverty alleviation.
