Interest in using information-based interventions to induce energy and water conservation has increased in recent years but have shown mixed evidence of their effectiveness. This paper seeks to answer two main questions - whether these programs are broadly effective in inducing conservation, and what are the most effective versions of these programs. Using a meta-analysis of 116 studies, we examine the effects of information-based interventions on residential customers' consumption of electricity, gas, and water. We find evidence of publication bias in this literature. After correcting for publication bias, meta-analysis results indicate that information-based interventions reduce consumption by an average of 6.24%, 95% CI [-10.72, -1.76]. In addition, we find that studies employing RCTs find smaller conservation effects, (-5.2%, 95% CI [−9.53, −0.51]). Our results show that the effectiveness of information-based interventions at the household level are significantly larger than those at the aggregate level (such as dorms and buildings). Finally, interventions with a shorter duration or with more frequent reporting show larger estimated effect sizes.

基于信息的干预措施对保护行为的影响:荟萃分析

近年来,人们对使用基于信息的干预措施以节约能源和节约用水的兴趣有所增加,但已证明其有效性的证据不一。本文试图回答两个主要问题-这些程序在诱导保护方面是否广泛有效,以及这些程序最有效的版本是什么。通过对116项研究的荟萃分析,我们研究了基于信息的干预措施对居民用户的电,气和水消耗的影响。我们在这些文献中发现了发表偏见的证据。纠正出版偏倚后,荟萃分析结果表明,基于信息的干预措施平均可减少消费6.24%,95%CI [-10.72,-1.76]。此外,我们发现采用RCT的研究发现较小的保护效果,(-5.2%,95%CI [−9.53,-0.51])。我们的结果表明,在家庭一级基于信息的干预措施的有效性显着大于总体水平(如宿舍和建筑物)。最后,持续时间较短或报告频率较高的干预措施显示出较大的估计效果。
