Cloud datacenters already consume ~2% of the world’s electricity. With the exponential increase in compute and data, especially given the recent explosion of generative AI, the world’s computing infrastructure has become a significant source of carbon emissions. In order to avoid an exponential rise in computing-related carbon emissions, we must rethink and retool cloud hardware, system software and web applications to become energy and carbon aware. The sustainable cloud computing and AI session at the NYC climate week will feature talks and a panel with researchers from industry and academia who are actively working on solving these hard and pressing problems.
