Volume 1:
Reducing and managing humanity's demand for energy is a fundamental part of the effort to mitigate climate change. In this, the most comprehensive textbook ever written on the subject, L.D. Danny Harvey lays out the theory and practice of how things must change if we are to meet our energy needs sustainably. The book begins with a succinct summary of the scientific basis for concern over global warming, then outlines energy basics and current patterns and trends in energy use. This is followed by a discussion of current and advanced technologies for the generation of electricity from fossil fuels. The book then considers in detail how energy is used, and how this use can be dramatically reduced, in the following end-use sectors:

- buildings
- transportation
- industry
- food and agriculture
- municipal services

The findings from these sector-by-sector assessments are then applied to generate scenarios of how global energy demand could evolve over the coming decades with full implementation of the identified and economically-feasible energy-saving potential. The books ends with a brief discussion of policies that can be used to reduce energy demand, but also addresses the limits of technologically-based improvements in efficiency in moderating demand and of the need to re-think some of our underlying assumptions concerning what we really need. Along with its companion volume on C-free energy supply, and accompanied by extensive supplementary online material, this is an essential resource for students and practitioners in engineering, architecture, environment and energy related fields.

Volume 2:
Transforming our energy supplies to be more sustainable is seen by many to be the biggest challenge of our times. In this comprehensive textbook, L.D. Danny Harvey sets out in unprecedented detail the path we must take to minimize the effects that the way we harness energy will have on future climate change. The book opens by highlighting the importance of moving to low carbon technologies for generation, then moves on to explain the functioning, potential and social/environmental issues around:

- solar energy
- wind energy
- biomass energy
- geothermal energy
- hydroelectric power
- ocean energy
- nuclear energy

It also covers the options for carbon capture and storage and the contexts in which low carbon energy can best be utilized (potential for community integrated systems, and the hydrogen economy). The book closes with scenarios that combine the findings from its companion volume (concerning the potential for limiting future energy demand) with the findings from this volume (concerning the cost and potential of C-free energy systems) to generate scenarios that succeed in limiting future atmospheric CO2 concentration to no more than 450 ppmv. Detailed yet accessible, meticulously researched and reviewed, this work constitutes an indispensible textbook and reference for students and practitioners in sustainable energy and engineering.

'Texts like these are vitally needed for the new generation of energy researchers and leaders.' Daniel M. Kammen, University of California, Berkeley 'These volumes provide a balance of energy technology and energy systems tutorial, balanced with an excellent education in the climate-energy nexus. As energy advances to be the 'front burner' issue that it needs to be and remain, texts like these are vitally needed for the new generation of energy researchers and leaders.' Daniel M. Kammen, Class of 1935 Distinguished Professor of Energy, University of California, Berkeley 'The approach is detailed and technical and should be useful as a reference work... Overall, it's an outstanding package... Recommended.' Renew 'probably the best books so far on sustainable energy for serious student use' Renew Praise for Vol 1: 'From understanding the Carnot Cycle in power plants and electrochemical processes in fuel cells to examining waste heat recovery within industry, this is the 'go to' book for those wanting to explore the many surprising opportunities for improving energy efficiency.' John A. 'Skip' Laitner, Director of Economic and Social Analysis, American Council for an Energy-Efficient Economy 'Scientific understanding and technological options can provide a successful approach to energy for sustainable development. Improved energy efficiency offers multiple sustainability benefits, including climate change mitigation. What are needed are political will, financial commitment and social readiness. This book is essential in today's debate.' Thomas B. Johansson, Professor, Lund University, Sweden 'Energy Efficiency and the Demand for Energy Services is remarkable for the scope of its coverage - the whole problem, not just a slice - and its depth, clarity and approachability. It will serve as an excellent textbook for a wide range of energy-related university-level courses.' John Straube, Associate Professor, Department of Civil Engineering & School of Architecture, University of Waterloo, Canada Praise for Vol 2: 'Provides a balance of energy technology and energy systems tutorial, balanced with an excellent education in the climate-energy nexus. As energy advances to be the 'front burner' issue that it needs to be and remain, texts like this are vitally needed for the new generation of energy researchers and leaders.' Daniel M. Kammen, Class of 1935 Distinguished Professor of Energy, University of California 'Carbon-Free Energy Supply is an impressive and comprehensive textbook. It concentrates on renewables but also includes nuclear power and fossil fuels with carbon capture and storage. It clearly demonstrates the technological and economic feasibility of a carbon-free future for the world.' Godfrey Boyle, Professor of Renewable Energy, The Open University, UK 'This book is a significant step forward for understanding how climate change mitigation can be effectively deployed. Technical and economic issues for each of the possible paths to achieve the goal are exhaustively presented, well documented and properly evaluated.' Professor Jos? Roberto Moreira, Brazilian Reference Center on Biomass, University of S?o Paulo, Brazil
