Next time you’re falling down a YouTube rabbit hole, think about this: all the watching, gaming and gramming we do is as polluting as flying. The internet is using a larger proportion of the world’s energy than ever before and, with the rollout of 5G, it’s set to keep on growing.

They used the same amount of energy as five African countries put together over an entire year.
