An overview of household technology adoption: promotion and transition implication at a community level

This study aims to comprehensively understand household energy technology adoption and explore technology justice while proposing specific strategies for technology promotion and energy transition at the community level. First, taking New South Wales (NSW), Australia, as an example, this study classifies the households via k-modes according to household energy technology adoption, and then spatial and climate distribution are analyzed by hot pot analysis and spatial autocorrelation. Next, the suburbs are classified according to the proportion of different household clusters. The results indicated four clusters of households. Notably, the study reveals higher spatial aggregation of Gas & Air-conditioning combined and Gas & No heating cooling combined households. The former is more prevalent in the hot-summer and cold-winter zones of NSW, while the latter is more common in hot zones of NSW. These findings suggest potential disparities in household energy technology adoption, particularly in hot zones of NSW, which may imply an injustice in access to suitable technologies. Finally, the suburbs in NSW are classified into six clusters, laying the groundwork for proposing implications for technology promotion and energy transition in these areas. This study provides valuable guidance for promoting household technology and facilitating energy transition at the community level. • Households were classified into four clusters based on technology adoption. • Injustice towards household energy technology adoption in NSW was disclosed. • Suburbs were classified into six clusters based on the proportion of different households. • Technology promotion and energy transition implication in different suburbs was obtained.
