Hintemann, R. (2015). Energy consumption of data centers in 2015. Berlin: Borderstep Institute.
The increasing digitization in all areas of the economy and society is resulting in an increasing need for processing power, which is also spurring the growth of the data center industry in Germany.

EnviroInfo & ICT4S, Conference Proceedings (Part 1) (S. 165–171). Presented at the Third International Conference on ICT for Sustainability (ICT4S 2015), Copenhagen.
The number of Internet-enabled end-user devices such as personal computers, notebooks, tablets, smartphones, etc. is increasing constantly. However, since the devices themselves are becoming ever more energy-efficient, their overall energy consumption in the use phase of their life cycle seems to be increasing only marginally, or even decreasing in some areas. In contrast, the energy consumption induced in data centers by the use of end-user devices is rising. The present contribution presents the results of a Borderstep Institute study on the development of personal computers conducted within the framework of the research project AC4DC.

Hintemann, R. (2014). The Future of Data Center Energy Demand – The Impact of the Changing Structure of Data Centers. Berlin: Borderstep Institut.
Within a few years, the structure and components of data centers can change completely. This applies not only to individual data centers, but also to the structure of the data center market at the national or international level. This poster shows the structure and development of the data center market in Germany. These are results of the project “Adaptive Computing for Green Data Centers” (AC4DC, www.ac4dc.com).

Presented at the Enviroinfo 2014 – ICT for Energy Efficiency, 28th International Conference on Informatics for Environmental Protection, September 10-12, 2014, Oldenburg.
Server virtualization is the fundamental prerequisite for using adaptive computing technologies. Therefore, this contribution focuses first on the extent to which server virtualization is used in data centers and calculates both the current figure and the development through 2020.

The IT industry in general and data centers in particular are subject to a very dynamic development. Within a few years, the structure and components of data centers can change completely. This applies not only to individual data centers, but also to the structure of the data center market at the national or international level. The sizes, types, and locations of data centers are changing significantly because of trends such as the consolidation of data centers, the increasing use of colocation data centers, virtualization, and cloud computing. The construction of large cloud data centers, for example Google in Finland, Facebook in Sweden, or Microsoft in Ireland, is an example of these developments. In consequence, there is an impact on the overall energy demand of data centers. This chapter discusses these developments and the impact on the overall energy consumption of data centers using the example of Germany.

The paper is based on the first study worldwide to analyze materials present in the equipment of data centers. The study develops a methodology which allows the calculation of the number of data centers of the various size classes and their average equipment with IT components and infrastructure elements, such as air-conditioning systems and power supplies. This enables detailed statements to be made on the materials present in the equipment of approx. 53,000 data centers in Germany.

The study ascertains the energy, equipment and material resources of German data centers for the reference year 2008, and predicts their development through 2015 in two scenarios (“Business-as-usual” and “Green IT”). Similar studies for other countries or regions are not known to date. To achieve the findings, a methodology has been developed which allows the calculation of the number of data centers of various size classes and their average equipment. Reference products are defined, and on this basis, a detailed determination of the material composition of data center components is made. This proceeding permits detailed statements on the material equipment of approximately 53,000 data centers in Germany to be made.
