Samenvatting
This synthesis is organized to present information on conservation measures by mode and by approach (i.e., policy, technology, operations). Distinctions are made between those measures or technologies that can be implemented now as compared to those that will be available in the future. Only limited attention is given to air, marine, pipeline, and other modes. Finally, an attempt is made to identify gaps in present knowledge of energy conservation techniques in order to define needed research. (Author/publisher)
