基于网络的云计算正在迅速扩展，以替代传统的基于办公室的计算。随着云计算变得越来越普遍，网络的能源消耗和计算云的计算资源将增长。这是在关注整个信息和通信技术（ICT）领域的能源消耗的需要的时候发生的。尽管数据中心的能源使用最近引起了很多关注，但关注的关注点较少，这是将用户连接到云的关键的传输和切换网络的能源消耗。在本文中，我们介绍了云计算中能源消耗的分析。该分析考虑了公共和私有云，并包括开关和传输以及数据处理和数据存储方面的能源消耗。我们表明，运输和开关中的能源消耗可能是云计算总能源消耗的很大一部分。云计算可以使计算能力更节能地使用，尤其是当计算任务低强度或罕见时。但是，在某些情况下，云计算比常规计算可以消耗更多的能量，而每个用户在自己的个人计算机（PC）上执行所有计算。
Network-based cloud computing is rapidly expanding as an alternative to conventional office-based computing. As cloud computing becomes more widespread, the energy consumption of the network and computing resources that underpin the cloud will grow. This is happening at a time when there is increasing attention being paid to the need to manage energy consumption across the entire information and communications technology (ICT) sector. While data center energy use has received much attention recently, there has been less attention paid to the energy consumption of the transmission and switching networks that are key to connecting users to the cloud. In this paper, we present an analysis of energy consumption in cloud computing. The analysis considers both public and private clouds, and includes energy consumption in switching and transmission as well as data processing and data storage. We show that energy consumption in transport and switching can be a significant percentage of total energy consumption in cloud computing. Cloud computing can enable more energy-efficient use of computing power, especially when the computing tasks are of low intensity or infrequent. However, under some circumstances cloud computing can consume more energy than conventional computing where each user performs all computing on their own personal computer (PC).
