GEYSER: Enabling Green Data Centres in Smart Cities

Abstract

Abstract. Information Technology is a dominant player of our modern societies; Data Centres, lying at the heart of the IT landscape, have attracted attention, with their increasing energy consumption being a constant topic of concern, especially when it comes to the negative impact on the quality of their surrounding environment. Nevertheless, recent technological and societal advances are paving the way for DCs to change their role from passive energy consumers into prosumers, thus, transforming themselves into leading players within their smart district surroundings. This paper describes the innovative GEYSER approach to enabling green networked DCs to monitor, control, reuse, and optimize both their energy consumption and production, and in particular from renewable resources, towards becoming active participants within Smart Grids and Smart Cities.

Sunburn—using excess energy of small-scale production for distributed computing

“…On the other hand, Zheng and Cai [59] study how online service providers can minimise their electricity consumption by using an energyaware load dispatching method among data centers in different geographical locations. Anghel et al [3] have a slightly similar approach by processing computational tasks in a data center also producing renewable energy. Cioara et al [9] have studied by simulations how a data center connected to a smart grid could improve its profitability and energy efficiency by shifting workload in time or using its backup power for energy production based on the energy supply and demand situation at the moment.…”
