This paper aims to investigate the energy consumption pattern in four sectors of Padang, Indonesia: residential, commercial, industrial and transportation sectors, under different urban population scenarios using a cohort model and statistical data. The analysis shows that the energy consumed in the residential sector has the major share in the total energy consumption in Padang. Details on energy consumption and the main driving forces in the four sectors have been presented. Decreasing urban energy consumption could be achieved by increasing efficiency of home appliances, promoting electricity saving behavior, increasing of public awareness for saving energy, and applying energy efficiency labeling for home appliances
