Project Description

Energy efficiency in datacenters is of strategic importance to Switzerland, as over 75% of the Swiss economy is service-based and depends on information technology (IT), which makes Switzerland one of top spenders of IT per capita. IT is also witnessing a major paradigm shift towards Cloud Computing with datacenters emerging as a key backbone of services at scale, making energy dissipated in datacenters a key concern even with moderate increases in IT electricity demands. In particular, because of Switzerland’s decision to abandon nuclear energy by 2034, improvements in energy efficiency are imperative to make up for half of the electricity otherwise furnished by nuclear power. Meanwhile, in Switzerland many IT departments for enterprises, research, and governmental organizations alike are at capacity with regards to their electricity budget. Thus, the only feasible solution to achieve energy sustainability is to drastically increase the power efficiency of data centers.
