An anonymous reader quotes a report from The Guardian: When “I can has cheezburger?” became one of the first internet memes to blow our minds, it’s unlikely that anyone worried about how much energy it would use up. But research has now found that the vast majority of data stored in the cloud is “dark data”, meaning it is used once then never visited again. That means that all the memes and jokes and films that we love to share with friends and family — from “All your base are belong to us”, through Ryan Gosling saying “Hey Girl”, to Tim Walz with a piglet — are out there somewhere, sitting in a datacenter, using up energy. By 2030, the National Grid anticipates that datacenters will account for just under 6% of the UK’s total electricity consumption, so tackling junk data is an important part of tackling the climate crisis.
Ian Hodgkinson, a professor of strategy at Loughborough University has been studying the climate impact of dark data and how it can be reduced. “I really started a couple of years ago, it was about trying to understand the negative environmental impact that digital data might have,” he said. “And at the top of it might be quite an easy question to answer, but it turns out actually, it’s a whole lot more complex. But absolutely, data does have a negative environmental impact.” He discovered that 68% of data used by companies is never used again, and estimates that personal data tells the same story. […] One funny meme isn’t going to destroy the planet, of course, but the millions stored, unused, in people’s camera rolls does have an impact, he explained: “The one picture isn’t going to make a drastic impact. But of course, if you maybe go into your own phone and you look at all the legacy pictures that you have, cumulatively, that creates quite a big impression in terms of energy consumption.”
Since we’re paying to store data in the cloud, cloud operators and tech companies have a financial incentive to keep people from deleting junk data, says Hodgkinson. He recommends people send fewer pointless emails and avoid the “dreaded ‘reply all’ button.”
“One [figure] that often does the rounds is that for every standard email, that equates to about 4g of carbon. If we then think about the amount of what we mainly call ‘legacy data’ that we hold, so if we think about all the digital photos that we have, for instance, there will be a cumulative impact.”
It’s time to boot, do your boot ROMs know where your disk controllers are?
