How green is our data?

Available for over a year

Digital Planet is looking at green tech during COP26. Firstly, we discover the green credentials of your favourite websites with the Green Web Foundation. Can we really make the internet more environmentally friendly? Also we’ll be hearing about the homes in Sweden’s Stockholm that are heated using waste heat from local data centres. And how a company in Wyoming in the US is using technology to change the way data centres are cooled, using liquid and not air, and then using this excess heat for agriculture. The programme is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington Studio Manager: Nigel Dix Producer: Ania Lichtarowicz (Image: A processing facility at the Riken Center for Computational Science in Japan) Credit: STR/JIJI PRESS/AFP via Getty Images)
