能源技术、政策和实践的最新进展加快了全球能源效率的提高速度,使2030年联合国可持续发展议程中确定的能源目标触手可及。然而,目标7.3要求到2030年将这一比率翻一番,要求对能源干预采取更实质性的回应。目前,能源干预措施未能在建筑物中达到最佳水平,而建筑物是最大的城市能源消费者。这是由于直接和间接影响的结合,通常被称为能源效率差距。在这里,我们比较了超过1880万个人的位置记录与大伦敦的建筑物能源消耗记录在一年的过程中。我们证明,间接(即,经常性流动产生的溢出效应(溢出效应)决定了城市建筑能源效率的扩散,远远超过了直接效应。这被理解为能源使用和社会互动交叉点的潜在时空依赖性的结果。此外,我们还考虑了经常性流动的关键作用(即,这些研究结果表明,为了提高目前的采用水平,干预措施必须针对作为能源消费和社会互动密集中心的时间和地点。因此,经常性流动为现有的旨在提高能源效率的有针对性的干预措施提供了可行的补充,支持实现联合国2030年能源目标的努力。
Recent advances in energy technologies, policies, and practices have accelerated the global rate of improvements in energy efficiency, bringing the energy targets identified in the 2030 United Nations (UN) Sustainable Development Agenda within reach. However, Target 7.3 requires this rate to double by 2030, demanding a more substantial response to energy interventions. At present, energy interventions are failing to reach optimal levels of adoption in buildings, which are the largest urban energy consumers. This is due to a combination of direct and indirect effects generally referred to as the energy efficiency gap. Here, we compare over 18.8 million positional records of individuals against Greater London’s buildings energy consumption records over the course of one year. We demonstrate that indirect (i.e., spillover) effects, arising fromrecurrent mobility, govern the diffusion of urban buildings’ energy efficiency, far outpacing direct effects. This has been understood as a consequence of underlying spatiotemporal dependencies at the intersection of energy use and social interactions. We add to this the critical role of recurrent mobility (i.e., the mobility of those urban populations who repeatedly visit certain locations, such as home and work) as a diffusion conduit. These findings suggest that in order to improve the current levels of adoption, interventions must target times and locations that function as dense hubs of energy consumption and social interactions. Recurrent mobility thus provides a viable complement to existing targeted intervention approaches aimed at improving energy efficiency, supporting efforts to meet the UN’s 2030 energy targets.
