Most people think the Internet of Things is a recent idea,maybe dating to aroundthe year 2000. In fact, the idea is some 15 years older than that. In 1985, the Internet was officially two years old. It linked up some 2000 hosts, and a handful of people used email. In that year, cellular phones were the size of bricks, and almost no one had one. And yet, in 1985, Peter T Lewis predicted thetwo could be combined, so devices could communicate over wireless links. "I predict that not only humans, but

After a hiatus of several years, climate change policy is taking off in the US, with the Biden-Harris Administration using the Inflation Reduction Act and the Energy Earthshot to accelerate the clean energy economy. But data center energy policy goes back a lot further than that. Stephen Harper, Intel's Global Director, Environment and Energy Policy, was there 20 years ago when data centers first came onto the climate change radar, and he's been tracking progress since then. As well as their own

Efforts to reduce the environmental impact of our digital world tend to start with the cooling systems at data centers, and rarely get any further. The tech industry created PUE as a simple metric which could express how efficiently power is delivered to the racks, but did not consider what happens to that power when it gets there. That’s not good enough, because poorly written software could be wasting that power in unnecessary loops and fruitless calculations. The Green Software Foundation has

2022/08/04

When a data center firm claims to be 100 percent carbon neutral, can we believe them? Does every electron used in that data come from a solar panel or a wind farm? Until we have reliable carbon accounting, we won't know for sure, and operators will continue to rely on renewable energy certificates (RECs) which match energy consumption over a year, instead of hour by hour. Simone Accornero, CEO of FlexiDAO says we need "RECs on steroids" to move to hourly carbon accounting,and a blockchain-based

As sustainability continues to become an increasingly important issue for data center owners and operators, many are tying their financing into ESG-related goals. The likes of Green Bonds see proceeds going towards specific green projects, while Sustainability-Linked Loans see interest payments tied to specific targets such as PUE or water use. Such financing options have been adopted by cloud and data center companies including Equinix, Digital Realty, Atos, Baidu, AirTrunk, and telcos such as

2022/06/09

The world needs hydrogen as part of the replacement for fossil fuels - and data centers could be the catalyst for that. Mark Monroe, Principal Engineer at Microsoft, explainshow the hydrogen economy works. He shows us that hydrogen is not just a proven alternative to diesel for backup,but brings other benefits with it. If data centers switch this small part of their energy needs to hydrogen, this could enable much larger industries to get started - and catalyze a hydrogen economy

It's easy to think that sustainable data centers are all about reducing carbon. In fact the earth faces a biodiversity crisis as big as the climate crisis. Data centers can have a role in fighting to prevent extinctions, and produce a lot of other benefits in the process. When you build a data center, you have to see the unintended consequences, says Michelle Wallace of data center promotion group Host In Ireland. Build badly, and local species will suffer. But it's also easy to get it wrong, to put

Data center automation is one thing, but what about automatons walking in the data halls? Robots in the data center are often discussed but rarely make it beyond the pilot project stage. Those that are deployed are often closer to Short Circuit’s Johnny 5 than Neill Blomkamp's CHAPPiE. Utah-based Novva data centers has deployed Boston Dynamics' Spot robot dog – possibly the most advanced robot that is currently commercially available – at its flagship data center and is looking to create a

Figures quoted in 2021 suggested that data centers and communications technology could use eight percent or even 20 percent of the world's electricity by 2030. That seemed too high to us, so we tracked down the original source of the quotes, only to find he feels the same way. Anders Andrae is an academic, currently working at Huawei's Swedish R&D center. Since his original 2015 paper he has revised his predictions down, but the old figures still often show up out of context. More importantly,
