Digital Emissions

We hear a lot about the environmental costs of air travel. Burning jet fuel currently contributes around 2.5% to total carbon emissions. Therefore, fly less or stop flying altogether we’re told. But what you don’t hear so much about is that Information Communication Technology (ICT) will be responsible for 3.5% of global emissions by 2020. A 2013 study suggested that the digital economy uses 10% of global electricity and this could double to 20% by 2025. The issue is data centres, but even an iPhone uses more power than a fridge. Tweet that.

PS – On a slightly related note, did you know that bitcoin mining consumes more power than Switzerland?
