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 book 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 concern ends with a brief discusing what we really need. Along with its companion volume on C-free energy supply, this is an essential resource for students and practitioners in engineering, architecture, environment and energy related fields.
