Environmental Aspects of Energy Alternatives

Abstract

Since the so-called ‘energy crisis’, practically all countries in the world have dedicated considerable attention to energy strategies. Some, such as France and Spain, have made straightforward commitments—;notably towards nuclear power—;whereas most have adopted series of measures aiming at further diversifying their primary and secondary energy sources.† All are, in addition, trying to develop ways and means to increase the efficiency of energy production, conversion and utilization. A great deal can be done in that field: indeed, a recent study carried out by the United Nations Economic Commission for Europe (UNECE, 1976a) indicates that the overall efficiency of the energy sector as a whole, currently about 15%, could reach 20 or even 30% in the early 1990s by the application of a set of quite stringent but feasible energy-saving measures. Economic activity of the 1990s could thus be twice as great as it is today, without requiring any increase in our present energy consumption.
