The impact of real-time energy consumption feedback on residential gas and electricity usage
通过随机对照试验，发现实时能耗反馈使居民天然气和电力消耗分别降低6.9%和2.2%，总能耗减少5.8%，主要机制是提高了能源使用成本的显著性。
We implemented a Randomized Controlled Trial to estimate the impact of real-time energy consumption feedback on residential energy use. A random half of the participant households were offered an energy consumption monitor that uses smart-meter data to relay real-time information on energy use. The feedback resulted in natural gas and electricity savings of, respectively, 6.9 and 2.2 percent; the total amount of energy consumed was reduced by 5.8 percent. We probe the underlying mechanisms by means of a survey and find suggestive evidence that the display’s main impact is via raising the salience of the costs of using energy.
