ABSTRACT
The input-output table is a matrix showing the flows of products – in money terms – between the various industries of a national economy. Using the 1963 US government input-output tables which divide the economy into 363 industries. energy costs of all commodities produced in the USA are derived. The results are presented as energy costs per unit of money value. which are appropriate for comparing money and energy costs for different commodities. and also energy costs per physical unit, which are useful in obtaining a relation between physical production and demands on primary energy sources.
In the next chapter, a separate independent study using 1963 and 1967 input-output data for the USA shows how different assumptions lead to different results.
