在过去十年中,人们对信息技术、其他消费电子设备、数据中心以及互联网分销网络(在较小程度上)用电量的增加表示担忧。与此同时,人们普遍预计,“智能”创新将有助于减少社会各部门的能源需求。然而,这种潜在的节省以及其他数字服务的日益使用,都取决于数字基础设施的持续扩张。本文重点讨论互联网流量的惊人增长,这是一个对能源需求具有重要影响的趋势。它概述了一个议程,以更好地了解数据需求如何变化。根据我们自己的研究结果,结合二级数据分析,我们研究了电力和数据峰值需求的一致性。数据的峰值似乎在晚上晚些时候下降,反映了在线娱乐的使用,但这远未固定。总体而言,该文件认为,更好地了解日常做法是如何变化的,与在线服务的提供和设计相一致,可以为减轻互联网能源使用最有问题的预测所需的政策和举措提供基础。
Over the last decade, concerns have been raised about increases in the electricity used by information technologies, other consumer electronic devices, data centres, and to a much lesser degree, Internet distribution networks. At the same time, ‘smart’ innovations are widely anticipated to help reduce energy demand across diverse sectors of society. Yet such potential savings, as well as the increasing use of other digital services, are predicated upon continued expansion of digital infrastructures. This paper focuses on the phenomenal growth in Internet traffic, as a trend with important implications for energy demand. It outlines an agenda to better understand how data demand is changing. Drawing on findings from our own research in combination with secondary data analysis, we examine the alignment of peak demand for electricity and data. Peaks in data appear to fall later in the evening, reflecting the use of online entertainment, but this is far from fixed. Overall, the paper argues that a better understanding of how everyday practices are shifting, in concert with the provision and design of online services, could provide a basis for the policies and initiatives needed to mitigate the most problematic projections of Internet energy use.
