Abstract There is still considerable uncertainty about the way in which energy supply constraints affect industrial thinking and activity. Yet this is an important issue in determining the effectiveness of conservation programmes and in formulating energy policy. In 1978 S. Mehra and A.G. Kefalas conducted a survey of US business attitudes and responses to energy constraints. Some of their findings were published in the September 1979 Energy Policy. In the article below they present the results of further analysis of their survey. In particular they examine correlations between perceived causes and preferred solutions of energy problems, organizational adjustments to energy constraints in energy intensive industries and the ways in which production operations have changed in response to supply problems.
