2. INTRODUCTION  Computing technology plays a more and more important role in our day to day Life.  Subsequently the associated high volume of energy consumption has become a major concern both economically and environmentally.  Green computing is emerging as an inspiring solution, which is developing computing technologies that can effectively reduce energy consumption which leads to significant CO 2 emission reduction.  “Green computing is to use computers and related resources in environment friendly ways”.

3.  It takes a lot of energy to create, package, store, and move every 10-20 megabytes of data.  Even with energy prices as cheap as they are now, it will soon cost more to power a computer for four years than it does to buy a new one.  Green computing has recently been advocated in literature to reduce energy consumption in computer systems. For example, in a mobile and embedded wireless network system, energy efficiency rather than the network throughput becomes the major concern.  Green computing practices were primarily introduced by the Environmental Protection Agency in 1992 with the launch of the Energy Star program.

4. STATEMENT OF THE PROBLEM  As an emerging topic in IT management, “Green IT” practices are drawing high interest among IT organizations as well as suppliers, manufacturers and service providers.  By keeping this view in mind, the researcher intends to undertake the study on “Indian Contribution to Green Computing: A Bibliometric Study”.  This study attempts to analyses the performance of Indian researcher working in the field of Green Computing in terms of, research concentration, authorship pattern, scattering of articles in different sources, Institution wise distribution and so on.

5. OBJECTIVES OF THE STUDY The major objectives are framed with the exclusive notion of the present study as mentioned below:  To examine the growth of research productivity of Green Computing during 1968- 2012.  To identify the Bibliographic form-wise distribution of publications in Green Computing in India.  To study the subject-wise breakup of publications.  To determine the authorship pattern and determine the degree of collaboration in Green Computing research.  To identify the country-wise collaboration research of publications.  To assess the Institution wise research concentration of Green Computing in India

6. METHODOLOGY  The data was collected from Engineeringvillage2 database during the period 1968-2012.  It can be seen that nearly 596 bibliographic records of contribution in field of Green Computing over the period of 45 years.  The researcher applied the search strings “Green Computing” is used for the data extraction from the database of INSPEC, COMPENDEX and GEOBASE (totally forty five years) download the records based on the above strings.  A total of 596 records were downloaded and analyzed as per the objectives of the study.

7.  This research study explores to examine the growth rate during the study period.  The study aims to analyze the thrust areas of research concentration on Green Computing research in India.  It is also analytical in nature with the suitable statistical tools applications in strengthening the empirical validity.

8.  The table could clearly see that during the period 1968 - 2012 a total of 596 publications were published.  The highest publication is 80 in 2011 followed by 55 papers in 2010 and 54 papers in 2008.  The lowest publication is 1 in 1968 and 1969. Year wise distribution of publications

18.  The paradigm shift over the period is a gradual increase in the study period but good response is observed in the year 2008, 2010 and 2011.  During 45 years period contributions in terms of number of publications is not significant.  A comparison of Indian output in relation to the world output may help in understanding the contribution in a better angle.  Though the records available in the Engineeringvillage2 reveal a small number, it is important that the Engineeringvillage2 covers only the Green computing Research Articles.
