Material world: forecasting household appliance ownership in a growing global economy

This paper presents a methodology for modeling residential appliance uptake as a function of macroeconomic variables, and presents forecasts of appliance diffusion through 2030 for several scenarios of economic (GDP) growth. The approach followed allows the modeler to construct a bottom-­up analysis based at the end use and the household level. It captures the appliance uptake and the saturation effect which will affect the energy demand growth in the residen­tial sector. With this approach, the modeler can also account for stock changes in technology and efficiency as a function of time.
