Until recently, power purchase agreements (PPAs) and unbundled renewable energy certificates (RECs) were the primary means for data center operators or managers to procure renewable electricity and RECs for their operations. Many companies are notβ¦
Across the world, data center owners and managers are striving to buy more renewable energy and reduce their dependence on fossil fuels. The global internet giants and the largest colocation companies have led the way with huge green energyβ¦
Transitioning to renewable energy use is an important, but not easily achieved, goal. Although the past decade has seen significant improvements in IT energy efficiency, there are indications that this may not continue. Mooreβs Law may be slowing,β¦
Recent extreme weather-related events in the US (the big freeze in Texas, fires on the west coast) have once again highlighted the need for data center operators to reassess their risks in the face of climate change. The topic is discussed in depthβ¦
In Uptime Instituteβs recent report on preparing for the extreme effects of climate change (The gathering storm: Climate change and data center resiliency), there were over a dozen references to the dangers of extremely hot weather, which canβ¦
Through 2021 and beyond, the world will begin to recover from its acute crisis β COVID-19 β and will turn its attention to other matters. Few if any of these issues will be as important as climate change, a chronic condition that will become moreβ¦
What we can expect for mission-critical digital infrastructure in 2021?Each autumn Uptime Institute, like many other organizations, puts together a list of some of the big trends and themes for the year ahead. This time, we have focused on five bigβ¦
Across the globe, data center operators are under pressure to make data centers more sustainable. To this end, efforts are underway to reduce carbon emissions, water consumption and waste. The big, global and largely US-headquartered giants of theβ¦
When the PUE (power usage effectiveness) metric was first discussed at a meeting of The Green Grid in Santa Clara, back in 2007, a microphone stand was placed in each aisle of the auditorium. The importance of the initiative was understood even thenβ¦
As discussed in Note #71 (In thunder, lightning, or in rain?), climate change requires data center managers to not only review existing emergency plans but also anticipate previously unforeseen challenges.
Data centers are built and sited to withstand all that Mother Nature can throw at them β or at least, is likely to throw at them β during their lifecycle. This has long been a given, practiced and understood by designers, planners and regulators.Butβ¦
One of the emerging trends in data centers is the use of lithium ion (Li-ion) batteries, both for distributed and centralized uninterruptible power supplies. Research by Uptime Institute and others predicts high levels of adoption in the years aheadβ¦
When the PUE (power usage effectiveness) metric for data centers was first agreed upon by the members of The Green Grid back in 2007, almost everyone in that crowded room in California agreed: This is not intended to be used as comparative metric;β¦
The tenth Uptime Institute annual survey is the largest and most comprehensive research study of its kind in the data center sector.
The average power usage effectiveness (PUE) ratio for a data center in 2020 is 1.58, only marginally better than 7 years ago, according to the latest annual Uptime Institute survey (findings to be published shortly).PUE, an international standardβ¦
