Are the announcements about net zero energy data centres merely marketing responses to the threat of regulation/legislation or are they a real possibility? With many of the elements required for genuine Net Zero beyond the control of data centre operators, including the re-use of waste heat for instance and the performance of the IT load, how can we realistically achieve this? Are we being seduced away from genuine solutions by Hyperscale companies who are effectively operating very large enterprise sites so not actually representative of the sector as a whole? Remember that an energy efficient building is not necessarily an energy efficient data centre! This presentation will explore these areas and more.
