The current hype for product carbon footprints of IT, policy initiatives, such as the European ecodesign directive and several research activities recently lead to the publication of numerous LCA results of laptop computers. A comparison of the various studies unveils a broad variance among the results, which cannot be explained solely by technical differences: LCA for IT products still faces severe...
The advancing digitization of all areas of the economy and society is generating significantly increasing demand for processing power. More and more data centers of ever larger size are being built worldwide, and their electricity consumption is constantly on the rise. Forecasts project a significant increase in the global electricity consumption of data centers in the next five years. The presentation...
Based on the data of a recent study, the paper will show and analyse the factors that contribute to the fast improvement of energy efficiency of ICT end-user devices over the past years. The main purpose of the paper is to outline future developments and challenges with respect to the further improvement of energy efficiency in the field of end-user devices. In the paper the authors will argue that...
To set the stage for the conference it is of interest to take a look back in order to try a look forward at potential upcoming research trends. For this purpose research topics addressed in Electronics Goes Green conferences since 2000 are quantitatively investigated with a keyword density analysis. The focus is on analysing the development of research topic clusters over time providing an expert...
Public authorities have an important role to play in mainstreaming green procurement for ICT. However, a life-cycle thinking approach in the procurement process is necessary today. Several LCA studies have shown that the manufacturing phase of ICT products have a proportionally increasing environmental impact as compared to the use phase. Thus, extension of the service life of ICT products has been...
This paper presents the energy saving potential of converged ICT and CE based on a case study for Germany. A specific focus is on the issue of networked standby.
The European regulation on standby under the Ecodesign Directive EuP/ErP is well progressed with one implementing measure on standby and off-mode in force (1275/2008) and one measure in preparation for networked standby. However, there are still many open questions on standby, ranging from international harmonisation, via measurement standards to product scope and mode definitions. This paper will...
Early replacement of EEE has often been argued in conjunction with the continuous improvement of energy efficiency in the use phase. Recent LCA studies show that the raw materials and manufacturing phase of many EEE have a proportionally increasing environmental impact. For mobile electronic products, an early replacement due to improved energy efficiency in the use phase is to some extent not reasonable...
The dynamic development of IT performance combined with a growing demand of ICT services in public and private sectors is resulting in an increasing energy consumption of centralized IT equipment in data centers. Nevertheless, energy efficiency measurements for data centers today are still focusing mainly on cooling and power supply infrastructure. Therefore, the main goal of the Intelligent Energy...
The paper explains and discusses the neologism Eco-Reliability from the three perspectives Ecology, Economy and Reliability or rather the interdependencies as a process of multi-criteria decisions. The focus is set on electronic appliances and their applications. Further on all phases of the lifetime from design to processing, use and end-of-life are taken into account. Because of this the potential...
The energy consumption of centralized IT-equipment and data centers has been a fast growing topic over the past few years. It is widely recognized that a number of effective measures exist that in many cases would allow energy savings of 20–60% or even higher. Following the motto “You can't manage what you don't measure.” Energy efficiency metrics are typically used for benchmarking the energy consumption...
Consumer electronics have yet to reap the full potential of green technologies and ecodesign. The European policy framework is supposed to foster the implementation of environmentally benign product design, but largely addresses substance restrictions and energy efficiency in the use phase only. Resource consumption, usage of recycled plastics, bio-based materials and fewer substances of health and...
