Why our growing use of technology is a threat to the planet. Ed Butler speaks to Ian Bitterlin, a visiting professor at the University of Leeds in the UK and an expert in the data centres that underpin the internet and use vast amounts of energy. Ruiqi Ye, a climate and energy campaigner for Greenpeace in Beijing, explains why data centres are adding to the climate change problem. Halvor Bjerke from Norway's DigiPlex, the Nordic region’s leading data centre supplier, tells us why putting more data centres in colder parts of the world could be part of the solution.
