Digital technologies are the backbone of the world economy. To make this crucial system work, there is a heavy reliance on massive data storage infrastructure. These networks of data centres require a huge amount of electricity to keep them running. Power requirement is not just for helping the data centres run, but also to keep the servers that house the data in a controlled environment operating effectively. The eventual results of this are massive heating and cooling bills, and costs if not checked have a way of eating into businesses’ revenues and profits.
