L’impronta ecologica della nostra cache

La memorizzazione dei dati potrebbe rappresentare molto presto l’8% dei consumi energetici mondiali.

Come ha raccontato Emily Chasan a Bloomberg, ci vuole un’enorme quantità di energia per immagazzinare tutto quello che i computer immagazzinano in modo da farci viaggiare veloci sui siti che frequentiamo.

Dice l’articolo che «al momento, i data center consumano circa il 2% dell’elettricità mondiale, ma si prevede che raggiungeranno l’8% entro il 2030. Inoltre, solo il 6% circa di tutti i dati mai creati è in uso oggi, secondo una ricerca di Hewlett Packard Enterprise. Ciò significa che il 94% si trova in una vasta “discarica informatica”, sebbene con un’imponente impronta di carbonio».

Ogni dispositivo collegato al cloud, ogni foto che facciamo, ogni mail che mandiamo, ogni messaggio vocale che registriamo richiede energia per essere immagazzinato e stare lì, a nostra disposizione nel caso in cui lo volessimo recuperare. Se solo pensiamo a quello che conserva ogni nostro cellulare, ogni nostro computer, ogni nostro dispositivo di uso giornaliero, ci rendiamo conto di quanto possa essere grande il problema a livello globale e di quanto sia destinato ad aumentare in fretta.

Anche se sempre più data center sono alimentati da fonti rinnovabili, hanno server più efficienti o sono collocati in luoghi molto freddi, i requisiti di archiviazione dei dati continuano ad aumentare. E se aggiungiamo al problema anche il mining di bitcoin non la finiamo più.

Bloomberg sostiene che è improbabile che gli aggiornamenti di efficienza energetica o altri miglioramenti tecnologici compensino le emissioni di gas serra dei dati, anzi dobbiamo pensare che il carico di lavoro nel campo del calcolo energetico sarà più che raddoppiato quando sempre più intelligenze artificiali arriveranno online. Più dispositivi sono connessi e più lavoro le persone svolgono nel cloud.

Bisognerà trovare delle soluzione e fare delle scelte per affrontare questo problema.

  • Your internet service provider (ISP) can see everything you do. While there probably isn’t a guy at Time Warner Cable sitting in a corner office watching your every move, many ISPs do compile anonymous browsing logs and sometimes sell them to advertising companies. With that data, advertisers can tailor their content directly to certain regions or browsing habits.This is one of the big reasons more and more people online are considering a virtual private network, or VPN, which can keep your online behavior private.

  • Hi there,

    For 12 years, I was in banking and finance, working and making money for other people. I would study and analyse financial markets to predict outcomes and advise companies and wealthy individuals where to put their money.

    My biggest client was a large casino group, but they had little idea of what was going on on their sites! So I got thinking – how could people such as me and you take advantage of this?

    Watch my video to find out my Roulette strategy and how it’s currently earning me over $1000 a day (yes – really!)… https://www.youtube.com/watch?v=gAP6ci4oVRo

    Thanks for reading,
    Daniele
