Excess memes and ‘reply all’ emails are bad for climate, researcher warns

Most data stored on power-hungry servers is used once then never looked at again

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 datacentre, using up energy. By 2030, the National Grid anticipates that datacentres 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.
