The purpose of the paper is to expand the data base for the W.D. Nordhaus study: The Demand for Energy (IIASA CP-76-1, pp. 511-587; see also IIASA RM 76-18) through the addition of centrally planned economies. The paper gives sources, definitions and shows final energy consumption and prices by type of fuel and sector of the economy and various macro-economic data, covering a span of 20 years. The compilations are based on official GDR statistics, and direct contributions made by GDR participants to workshops on "Energy Demand" and "Regional Energy/Environmental Systems" held by IIASA at Laxenburg in 1975. Re-grouping of the data to conform with the concepts used for the Nordhaus study are the responsibility of the author
