Abstract: This research examines household energy technologies adopted in the past decade in the state of New South Wales, Australia. The examination addresses regional differences that need to be considered in the promotion of clean, renewable energy. The study analyses a longitudinal dataset (2011–2019) of Building-Sustainability-Index-certificated dwelling units in metropolitan (n = 167,883) and rural (n = 100,675) areas. The sampled units have adopted a variety of technologies for heating water; heating, cooling and lighting homes; and cooking food. The results show a significant difference between the two examined regions in terms of adoption rate, with the p-values of the Chi-squared tests all below 0.001. This difference can be attributed to the complex socioeconomic, lifestyle and living conditions of the two different regions. Based on the Bass model (with p-values < 0.05), most technologies will reach saturation, whereas a few will continue to grow, such as the combination of ceiling fans and air-conditioning for bedroom cooling in rural areas. This study makes suggestions for policies to promote clean, renewable energy among households on the basis of regionality.
