Use more image captions as often as possible today , you see a reduction in power usage effectiveness ( PUE ) from around 2.5 to about 1.55 PUE ,” he comments . “ You see some data centres out there now that operate at around 1.1 or 1.15 PUE . That is incredibly efficient in comparison to where we ’ ve been .”
As Garner explains , the data centre sits in an interesting area when it comes to the sustainability conversation . “ When we talk about sustainability and how bad data centres are within the sustainability agenda , only 1 % of the energy consumption worldwide comes from data centre use ,” he says . “ Around 3-4 % of carbon emissions worldwide come from data centre use .
“ It ’ s still a problem ,” he clarifies . “ The numbers are big enough for it to be significant , and it ’ s important that we continue to address it and challenge ourselves to move forward .
“ But if 99 % of energy is being used elsewhere , how do we start to address those industries and areas to try and reduce carbon output and energy usage ?”
This , he describes , is where the data centre market really comes into play .
