We already know that AI models in training and operations consume lot of electricity since the hardware used has GPUs as accelerators. In order to make data centres greener, we have to focus on power consumption. AI will account for 20 per cent of the total electricity consumption by 2030.

To begin with, we should make hardware efficient by using server virtualisation and containerization. As far as possible, we should use renewable energy, e.g. use of solar panels, wind turbines etc. Data centres should use effective cooling mechanisms, e.g. using hot aisle and cold aisle containment, air flow control, liquid cooling systems. There should be optimised resource allocation. Lastly, data centre infrastructure management (DCIM) should be deployed.
