Energy, Demand and Planning brings together a group of distinguished authors from many relevant disciplines, under the auspices of the Watt Committee on Energy. The authors were asked to consider the effects of policy decisions that might be taken now on the planning of the world energy industries in the coming half-century or so. Discussion is held on such key topics as technological change, sustainable development, global warming and the effects of population growth, all of which require policy decisions at national and international levels, affecting the daily lives of people in both advanced and developing countries.
