1972年至1990年间，新加坡居民用电量以每年8.8%的速度增长。对长期收入和价格弹性的估计分别为1.0%和−0.35.已经发起的节能运动被发现对消费的影响微乎其微。一项统计分析表明，消费对气候变量的微小变化很敏感，特别是温度，这与环境控制用电器的日益普及密切相关。随着家庭收入的增加，家用电器的拥有量出现了暂时的增长。然而，还涉及其他因素，因为在消除收入影响后，所有权水平也会随着时间的推移而增加。未来电力需求增长的很大一部分将来自对空调日益增长的需求，这将导致用电量的季节性变化越来越大。
Residential electricity consumption in Singapore increased at a rate of 8.8% per year between 1972 and 1990. Estimates of the long-run income and price elasticities are 1.0 and −0.35, respectively. The energy-conservation campaigns that have been launched are found to have marginal effects on consumption. A statistical analysis shows that the consumption is sensitive to small changes in climatic variables, particularly the temperature, which is closely linked to the growing diffusion of electric appliances for environmental controls. There has been a temporal increase in the ownership levels of appliances associated with increasing household incomes. However, other factors were involved since the ownership levels would also increase over time after the elimination of the income effect. A large part of the future growth in electricity demand will arise from the growing need for air-conditioning, which will lead to increasingly large seasonal variations in electricity use.
