[en] This paper reviews the current energy supply and consumption. Worldwide, there was an increase in the annual energy consumption of 5% between 1955 and 1973 and of 2.7% between 1973 and 1979, but there was a decrease of 0.2% from 1979 to 1983. The role of oil grew from 31% to 47% of world energy consumption between 1955 and 1973 but dropped to 40.3% in 1983. Despite an overall decline in energy consumption in the last few years, the consumption of electricity continues to grow. Nuclear energy has not completely recovered from the crisis of the second half of the 1970's. This is in part because of social acceptance factors and hostility to large plants. World energy problems will continue over the next 20 years. A comprehensive approach is needed which stresses renewable energy and nuclear fission. (author)

[en] This second part of a preview on the development tendencies in the energy sector makes it clear that alterations can only be made very slowly and at considerable expense. This refers, above all, to decreasing the dependence on crude oil. It is expected that the use of national hard coal, intensified for reasons of energy policy, will be determined by revised growth rates. (UA/LN)

[en] Discussion on energy saving and its methods proceeds with the following topics: merits and demerits of petroleum - expanding distortion along with its many merits; the background for the emergence of energy soft paths (such as solar heat) - non-depletion energy in energy saving; industrial approaches to energy saving - mere 10% in ten years; possibilities and difficulties of the energy-saving livelihood - advanced ways of life hardly reversible; studies on the fundamentals for energy problems - technological breakthrough as a key. Along with the brilliant civilization brought about by petroleum social distortions have appeared such as the unstable economics and pollution. Energy soft paths, as compared with energy hard paths (such as nuclear energy), possess number of advantages like small fund requirement and environmental safety. Since much cannot be expected from industrial and livelihood efforts, the breakthrough in technology appears to be promising, such as the utilization of solar energy and the switching from thermochemistry to biochemistry.

[en] Studies on methodological development and criteria identification included atmospheric transport; hydrologic analysis; validation of a forest growth model; agricultural applications; distribution of sensitive species; impacts of transmission line corridors; and environmental objectives in energy facility siting. Research focuses on impacts associated with the siting and operation of coal technology facilities in the southeastern United States
