| Abstract | Variability and intermittency of green power is the main obstacle for its utilization. Different from other power consumption, due to the distributed nature, load balancing on geographical range can be used to dispatch computing tasks to the data centers with abundant renewable energy. The premise of this new strategy is: there is always abundant green power at some of the renewable power portfolio, yet this is not always the truth. The stable availability of renewable energy is built on the compensation of different power plants, but due to the constraint of constructed data centers and the on-site powering strategy, this compensation effect has not been fully explored. In this paper, we propose a solution for Renewable Energy Portfolio Optimization (REPO) problem, and take wind farm location selection as an example to stabilize the variable and intermittent wind power. The simulation is conducted based on the real-world climatic traces from 607 candidate wind farms. The optimal renewable energy portfolio can provide stable wind power supply at the price of 70 USD/MWh. When simulated with Google workload trace of May 2011, with installed capacity 4 times of average power demand, REPO can save 59.5% of energy while a combination (on Google data center locations) without consideration of mutual compensation could only save 30%. |

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.
