Information and communication technologies (ICT) are increasingly permeating our daily life and we ever more commit our data to the cloud. Events like the COVID-19 pandemic put an exceptional burden upon ICT infrastructures. This involves implementation and utilization of data centers, which increasingly contribute to energy and environmental impact. In this work, we address strategies to improve energy efficiency of data centers, to enhance sustainability towards energy resource and the environment. Among key strategies are innovative cooling technologies, use of natural resources, automation techniques, low-power electronics, and equipment with extended thermal limits. Research perspectives are identified and estimates of improvement opportunities are presented.

Role Of Information

AbstractSeveral decades of research have addressed the role of information and communication technologies (ICTs) in industrial-organizational (I-O) psychology. However, segmented research streams with myriad terminologies run the risk of construct proliferation and lack an integrated theoretical justification of the contributions of ICT concepts. Therefore, by identifying important trends and reflecting on key constructs, findings, and theories, our review seeks to determine whether a compelling case can be made for the uniqueness of ICT-related concepts in studying employee and performance in I-O psychology. Two major themes emerge from our review of the ICT literature: (a) a technology behavior perspective and (b) a technology experience perspective. The technology behavior perspective with three subcategories (the “where” of work design, the “when” of work extension, and the “what” of work inattention) explores how individual technology use can be informative for predicting employee well-being and performance. The technology experience perspective theme with two subcategories (the “how” of ICT appraisals and “why” of motives) emphasizes unique psychological (as opposed to behavioral) experiences arising from the technological work context. Based on this review, we outline key challenges of current ICT research perspectives and opportunities for further enhancing our understanding of technological implications for individual workers and organizations.

Abstract The digitalization current is among one of the most relevant factors that currently drive transformation in the economy, with different degrees of impact across the main segments of the economy. As the topic of sustainability is now on the agenda of the biggest economic players, digitalization and the ability to leverage Information and Communication Technology opportunities have been recognized as drivers for innovation and change and a means to reach the sustainability goals. Reaching energy efficiency has been among the main objectives of both the public and the private sectors, leading to an increased interest in recognizing and capitalizing on energy efficiency opportunities. This in turn has an impact on the overall energy productivity, defined as the economic output per unit of energy. While this indicator has relevance at both micro and macro level, it is important to identify which makes some countries perform better than others. In the current economic context, studying how the performance of countries in the digital era correlates with the energy productivity can reveal further information on how it can be improved. The Networked Readiness Index is an indicator which assesses how well a country can capitalize on digital technologies and whether their usage of Information and Communication Technology has a relevant socio-economic impact. This paper analyzes which components that are assessed in a country’s Networked Readiness Index might influence energy productivity. Based on a panel data analysis performed on European countries, the study identifies that the individual usage of Information and Communication Technologies, the business and innovation environment and the usage of ICT by the business segment could have an impact on the energy productivity of a country.

In this paper, we address the management of Data Centers (DCs) by considering their optimal integration with the electrical, thermal, and IT (Information Technology) networks helping them to meet sustainability objectives and gain primary energy savings. Innovative scenarios are defined for exploiting the DCs electrical, thermal, and workload flexibility as a commodity and Information and Communication Technologies (ICT) are proposed and used as enablers for the scenarios’ implementation. The technology and scenarios were evaluated in the context of two operational DCs: a micro DC in Poznan which has on-site renewable sources and a DC in Point Saint Martin. The test cases’ results validate the possibility of using renewable energy sources (RES) for exploiting DCs’ energy flexibility and the potential of combining IT load migration with the availability of RES to increase the amount of energy flexibility by finding a trade-off between the flexibility level, IT load Quality of Service (QoS), and the RES production level. Moreover, the experiments conducted show that the DCs can successfully adapt their thermal energy profile for heat re-use as well as the combined electrical and thermal energy profiles to match specific flexibility requests.

The Rich

Empowered by the emergence of novel information and communication technologies (ICTs) such as sensors and high-performance digital communication systems, Europe has adapted its electricity distribution network into a modern infrastructure known as a smart grid (SG). The benefits of this new infrastructure include precise and real-time capacity for measuring and monitoring the different energy-relevant parameters on the various points of the grid and for the remote operation and optimization of distribution. Furthermore, a new user profile is derived from this novel infrastructure, known as a prosumer (a user that can produce and consume energy to/from the grid), who can benefit from the features derived from applying advanced analytics and semantic technologies in the rich amount of big data generated by the different subsystems. However, this novel, highly interconnected infrastructure also presents some significant drawbacks, like those related to information security (IS). We provide a systematic literature survey of the ICT-empowered environments that comprise SGs and homes, and the application of modern artificial intelligence (AI) related technologies with sensor fusion systems and actuators, ensuring energy efficiency in such systems. Furthermore, we outline the current challenges and outlook for this field. These address new developments on microgrids, and data-driven energy efficiency that leads to better knowledge representation and decision-making for smart homes and SGs.
