The large amounts of energy consumed by residential appliances and space conditioning equipment make this sector a fruitful area for efficiency improvements. We examine eight major residential appliances that in the US currently consume 9.4 exajoules/year (8.9 quads/year) representing more than 12 percent of total 1984 US energy use. Expenditures on energy for these appliances totaled over $56 billion in 1984. Or results indicate that improving the efficiency of all these appliances to economically optimal levels would reduce these annual expenditures by almost thirty percent, a savings of $17 billion per year. In steady state, the annualized additional investment cost to achieve this efficiency improvement is $7 billion, so the net savings is about $10 billion per year. This paper describes and analyzes energy efficiency choices for residential appliances and space conditioning equipment. 7 refs., 5 figs., 8 tabs.
