If no specific action to improve the energy efficiency is taken, electricity consumption of data centres is expected to rise to 104TWh a year by 2020. Furthermore, CO2 emissions from the IT-sector, estimated to be 2% of total global CO2 emissions, equivalent to that of the airline industry, would increase significantly.
The EU Code of Conduct for Data Centres launched today by the European Commission provides guidelines, recommendations and best practices, which could lead to a reduction in energy consumption of data centres of up to 20%. This work is in line with the 2020 energy saving targets making an important contribution within the ICT sector.
The key aim of the Code of Conduct is "to inform and stimulate Data Centre operators to reduce energy consumption in a cost-effective manner without hampering the critical function of the facility". This is achieved through a series of best practice recommendations which focus on design in areas such as software, IT architecture and infrastructure. Industry has responded extremely positively to the code, and a number of operators have already started to implement many of the best practices from earlier drafts of the code of conduct.
The European Commission's Joint Research Centre, is a provider of scientific-technical support to EU policy making and as such has initiated this and other codes of conducts in the energy efficiency area . Developed over the last two years, reviewed and refined by a wealth of stakeholders including industry experts from both data centre owners and operators, as well as equipment vendors and Member State experts, the code has become regarded as “the source of information to run an energy efficient Data Centre”.Best practices
o IT equipment: This includes efficient servers and virtualisation: instead of having many servers running at low utilisation, virtual servers are created inside a few servers, thus allowing the server to run at full load, which is more efficient and can result in other servers being switched off.
o Environmental conditions: Servers dissipate a significant amount of heat. Currently server rooms are cooled to low temperatures (e.g. 22°C). This strict temperature regime is not necessary as server rooms can operate at 30° and higher degrees of humidity, therefore eliminating the need to “overcool” Data Centres.
o Efficient management of environmental conditions: air conditioning and air management is one of the key energy demands. Poorly designed Data Centres mix cold and hot air (as in a normal office), but best practice is to keep them well separated, and to provide cooling exactly where it is needed on the server CPUs. In addition to the extended temperature ranges, Data Centres could run on natural cooling as opposed to cold air produced by chillers.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
