根据Uptime Institute发布《2018数据中心调查报告》显示,2007年,全球数据中心PUE平均值为2.5,2013年PUE已经降低了1.65,最新的数据显示,2018年全球数据中心PUE为1.58,报告显示,虽然数据中心单机柜平均密度仍然很低,但呈现快速提升的趋势。2017年,67%的机柜密度低于6千瓦(KW),只有9%的单机柜密度达到10千瓦以上。而2018年,已经有69%的机柜密度达到了10-29千瓦。在2016年时,只有一些高性能数据中心的机柜密度达到了26千瓦。(参考Uptime Instiute RESEARCH <Global Data Center Survey ADVISORY 2018>)

The roles of the participants range from IT and facilities management to executive, with senior-level participants at the VP level and above. Multiple geographic regions are represented, providing a global perspective. Most respondents (62%) are from the large, mature data center markets of the U.S., Canada, and Europe, with the balance spread across a mix of emerging data center markets and smaller regions.
The Green Grid’s power usage effectiveness (PUE) metric has become the industrypreferred metric for infrastructure energy efficiency for data centers. PUE does not take into account the efficiency of IT or networking equipment (or software applications), and it was designed only to benchmark efficiency gains over time at an individual site rather than to compare one facility against another. While the data center industry has long acknowledged these limitations of the metric, PUE remains the de facto efficiency standard and one that the Uptime Institute has been tracking for over the past decade.
In 2007, average PUE was 2.5 in a survey of Uptime Institute’s Network Members (a global user group of large data center owners and operators). This improved to 1.98 in our inaugural industry survey in 2011, and to 1.65 in our 2013 survey. Improvements since then have been incremental; in 2018, the average PUE was 1.58.
