Energy use in two large cities: A comparison of Hong Kong and Sydney, Australia

Abstract

A range of methods and assumptions is presented for drawing up complete energy budgets for individual consumption sectors and for the detailed study of the spatial distribution and seasonal and diurnal variation of energy use in Hong Kong. The energy use per capita in Hong Kong is just over one‐third of that in the Sydney region, whereas the intensity of energy use per unit area in Hong Kong is nearly twice that in Sydney. Midwinter daily energy use in Sydney's City area reaches 49 percent of the incoming solar radiation whereas values of 180 percent are reached in the Hung Horn region of Hong Kong.
