在电力部门，通过技术和行为改变进行节能，估计每年可节省1.23亿公吨碳，占美国家庭直接排放量的20%。在这篇文章中，我们调查了非价格信息策略激励保护行为的有效性。我们引入基于环境和健康的消息作为一种行为策略，以减少家庭能源消耗并促进节能。在一项使用实时电器水平能量计量的随机对照试验中，我们发现，环境和基于健康的信息战略，即传达电力生产的环境和公共健康外部性，如磅污染物、儿童哮喘和癌症，在推动家庭行为改变方面优于节省金钱的信息。与对照组相比，基于环境和健康的信息治疗促进了8%的能源节约，对有孩子的家庭尤其有效，他们实现了高达19%的能源节约。我们的结果是基于对118个居民在8个月内进行的340万小时电器水平千瓦时观测得出的结果。我们与居民消费者讨论了节约成本信息和环境健康信息策略的相对影响。
In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environment and health-based messaging as a behavioral strategy to reduce energy use in the home and promote energy conservation. In a randomized controlled trial with real-time appliancelevel energy metering, we find that environment and health-based information strategies, which communicate the environmental and public health externalities of electricity production, such as pounds of pollutants, childhood asthma, and cancer, outperform monetary savings information to drive behavioral change in the home. Environment and health-based information treatments motivated 8% energy savings versus control and were particularly effective on families with children, who achieved up to 19% energy savings. Our results are based on a panel of 3.4 million hourly appliance-level kilowatt-hour observations for 118 residences over 8 mo. We discuss the relative impacts of both cost-savings information and environmental health messaging strategies with residential consumers.
