Energy cost of living, 1972–1973
The total energy requirements of household consumption of all goods and services have been calculated. Source for consumption data is the 1972–1973 Bureau of Labor Statistics (BLS) Consumer Survey. These are converted to energy terms using input-output energy intensities. The dependence of household energy use on expenditures, number of household members, degree of urbanization, and other demographic-economic factors, has been investigated graphically and statistically. The major factor determining energy requirement is expenditure level, but this can be affected by up to about 15% by variation in the other factors. In agreement with previous work based on the 1960–1961 BLS Survey, we find that 1.(1) the dependence of total energy requirements on expenditures shows a tendency to saturation;2.(2) about one-half of the total energy of the average household is a result of the purchase of fuels and electricity while the other half results from the purchase of non-energy commodities. Application to the analysis of an energy tax and rebate program is discussed briefly.
