UK government asks people to delete old emails to reduce data centres' water use

As to the efficacy of the recommendation:

From The Verge's coverage[1]:

"The Environment Agency didn’t immediately respond to an inquiry from The Verge about how much water it thought deleting files might save, nor how much water data centers that store files or train AI use in the UK’s drought-affected areas."

And Tom's Hardware's[2]:

"Perhaps more pertinently, the advice rings hollow because it's likely not very sensible. While it's true that data centers do consume large amounts of water through evaporative cooling (where it's used), the vast majority of this power draw comes from CPU and GPU computation, not the storage of pictures and emails. Once the data is stored, the storage devices generate very little heat and are often spun down (placed into low- or no-power states) and called upon only when needed."

An average person's entire archive would likely easily fit on a small 64 microsd card. Which is like $10 bucks...
