数据中心是托管广泛使用的互联网服务的大型服务器场，每年在全球碳排放量中所占比例较大。数据中心越来越多地通过使用屋顶太阳能电池板的清洁可再生能源为其服务器提供部分电力来减少排放。虽然一些客户看重可再生能源服务器，但许多其他客户却漠不关心。我们认为，现场生产的可再生能源应尽可能集中在绿色客户使用的服务器上。本文介绍了一种新的指标，即可再生能源供电实例，用于衡量数据中心中可再生能源的集中度。我们对可再生能源数据中心进行了基于模拟的研究，重点关注并网——最常用于整合可再生能源的设备。我们发现并网布局对可再生能源集中度具有一阶效应。
Datacenters, the large server farms that host widely used Internet services, account for a larger fraction of worldwide carbon emissions each year. Increasingly, datacenters are reducing their emissions by using clean, renewable energy from rooftop solar panels to partially power their servers. While some customers value renewable-powered servers, many others are indifferent. We argue that renewable energy produced on site should be concentrated as much as possible on the servers used by green customers. This paper introduces a new metric, the renewable-powered instance, that measures the concentration of renewable energy in datacenters. We conducted a simulation-based study of renewable-energy datacenters, focusing on the grid tie — the device most commonly used to integrate renewable energy. We found that grid-tie placement has first-order effects on renewable-energy concentration.
