Keys to Smart Home Diffusion: A Stated Preference Analysis of Smart Meters, Photovoltaic Generation, and Electric/Hybrid Vehicles

As expectations have risen about the deployment of smart grids, it is important to investigate the diffusion process of smart equipment such as smart meters, photovoltaic generation, and electric/hybrid vehicles. However, since the revealed preference data have not been accumulated for smart equipment diffusion, this paper conducts a conjoint analysis to examine consumers’ stated preferences on the basis of an online survey administered in March 2011. A mixed logit model that allows for individual heterogeneity is adopted for estimation, and willingness-to-pay values are calculated for the attributes. Furthermore, the rates of diffusion, the reduction of greenhouse gas emissions, and interdependencies among types of smart equipment are investigated.
