| Abstract | In recent years, energy efficiency has become a major focus of data centre designers and operators. This has predominantly been due to the rising cost of energy and the exponential increase in the absolute energy consumption of data centres. As carbon taxes, emissions trading and environmental imperatives become an increasing influence in the regions in which data centres are based, measuring and controlling the emissions resulting from the energy consumed in a data centre will become as important as controlling the energy consumption itself. In this paper, two bodies of research are investigated: granular energy monitoring in data centres and electricity generation emissions calculation. We propose a method to accurately calculate the emissions caused by a single piece of computation by correlating the two areas. It is shown that a saving of 45% of the resultant emissions of scheduling a piece of computation can be made by choosing one of two contrasting times with different marginal power plants on the Irish electricity grid. This saving increases to over 99% at times when wind generation is being curtailed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
