Abstract: The link between climate and energy consumption has been widely established in many cities. The residential electricity consumption majorly for space conditioning is especially responsive to the outdoor climate. As a hot and humid tropical city, Singapore is expected to see increasing residential electricity consumption with global climate change. In this study, a multiple regression analysis is performed to relate the residential electricity consumption per capita and per household with outdoor climate during a 12-year period (2005–2016). The per-capita electricity consumption during 2008–2016 sees substantial decrease from that during 2005–2007, possibly due to the various energy saving measures taken by Singapore government. The different responses to outdoor climate variation in different household types are examined. It is found that generally dwellers in public households are more sensitive to outdoor climate variations, while private household occupants are not much affected by climate. Due to increasing ownership of electricity-consuming appliances in 1–2 Room and 3 Room public households, their electricity consumptions show a consistent increasing trend during the period studied. Under the worst scenario of projected future temperature increase, the per-capita and per-household electricity consumptions are projected to increase by 47% and 41%, respectively.
