Abstract
This paper aims to analyze quantitatively the growth and development of wind power
generation in world in terms of publication output as reflected in Scopus database during
1980 to 2014(35 years). Total of 20,779 papers published by the researchers in the field
Wind Power Generation (WPG) in various archers to various domains. Firstly, among
the subject category Engineering topped with 38% of documents, in source type category
Conference Papers were 48% as document type and the most preferred journals were
Renewable Energy 6%. Secondly the contributed institutions the North China Electric
Company ranked first with 2.3% papers and the Country based analysis China ranked 1st
with 18% publications followed by USA 16% and India ranked 5th with 5%. Finally Year
wise analysis showed that WPG papers gradually increased with average 594 papers per
year, in 2012 topped with 2706 papers and lowest 42 in the year 1989.
Keywords: Wind Energy, Wind power, Wind Power Generation (WPG), Scientometric Analysis, Year
wise and Authorship pattern, etc.
1. Introduction
Wind power is one of the renewable energy sources that produce no greenhouse gas emissions
during power generation and is an alternative to fossil fuels and it occupies little land. Wikipedia
describes “Wind is a form of solar energy. Winds caused by the uneven heating of the atmosphere by the
sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns modified by the
earth's terrain, bodies of water, and vegetative cover. This wind flow when harvested by modern wind
turbines used to generate electricity.
Denmark generating around 40% of its electricity from wind, and at least 83 other countries
around the world are using wind power to supply their electricity grids. Wind power production was
around 4% of total worldwide electricity usage, and gradually rising. In the terms of installed wind power

capacity in the world, India has the fifth largest one. Indian wind energy production, the Wikipedia
describes from various collection resources “As of 31 March 2015 the installed capacity of wind power in
India was 23,444 MW, mainly spread across Tamil Nadu (7,253 MW), Gujarat (3,093
MW), Maharashtra (2,976 MW), Karnataka (2,113 MW), Rajasthan (2,355 MW), Madhya Pradesh (386
MW), Andhra Pradesh (916 MW), Kerala (35.1 MW), etc.
Tamil Nadu has become a leader in Wind Power in India. According to TEDA (Tamil Nadu
Energy Development Agency, The wind installed capacity in 7349 MW as on 31.07.2014. This is 36% of
the country’s total wind installed capacity. The Muppandal wind farm in Tamil Nadu the total capacity is
1500 MW, which is the largest in India. (Table 1 and Figure 1 show that top 10 countries wind power

3. Objectives
The main objective of the study is to present the growth of literature and make the quantitative
assessment of status of Wind Power Generation (WPG) research by analyzing the various features. The
specific objectives are:
• To identify the quantum of wind power generation literature and its growth during the pried 1980
to 2014.
• To identify the Author, document type, Source type, Subject and country wise distribution of
global WPG research output.
• To measure the Institution and Language wise distribution in WPG research literature.
4. Methodology
The required data collected from Scopus database for the period 1980 to 2014, nearly 20,779
bibliographic records of contribution in the field of Wind Power Generation over the period of 35 years.
The researcher applied the search string “Wind Power Generation” that has used for the data extraction,
total 20,779 records downloaded and analyzed by using MS Excel software applications as per the
objectives of the study. This research study also going to explore the growth rate and relative growth level
during the study period. The study aims to analyze the thrust areas of research concentration on Wind
Power Generation (WPG) research.

Scopus is a bibliographic database containing abstracts and citations for academic journal articles.
It covers nearly 22,000 titles from over 5,000 publishers, of which 20,000 are peer-reviewed journals in
the scientific, technical, medical, and social sciences. Owned by Elsevier and is available online
by subscription. Searches in Scopus also incorporate searches of patent databases. Scientometrics is the
quantitative study of the disciplines of science based on published literature and communication. This
could include identifying the emerging areas of scientific research, examining the development of
research over time, or geographic and organizational distributions of research.
5. Results and Discussions
5.1. Year-wise distribution of Publications
During the study period 1980 to 2014, the year wise analysis reflected with average 594 papers
per year. From the year 1980 the wind power generation articles gradually increased in particular after the
year 2007 get the momentum in this field and topped with 2706 papers in the year 2012 and the lowest
just 42 in the year 1989. The trend shows that Wind Power Generation (WPG) publications have
gradually increased. (Table 2 and Figure 2 show that the 35 years of contributions).

research publications and ranked 1st with 18% publications followed by USA 16% and India ranked 5th
with 5%. Source wise analysis shows that, the highest numbers of publications were in Renewable Energy
6%), Energy Policy 359 3%, IEEE Power and Energy Society General Meeting 3%.This analysis
classifies papers it indexes Engineering 38%, Energy 34%, Computer Science 7% with 27 various Subject
Areas. Among the languages, English topped with 90% publications followed by Chinese with 7%),
German 1%, Japanese 0.86%) and so on. In the Year wise analysis showed that Wind Power Generation
papers gradually increased with an average of 594 records per year in particular after the year 2007 get
the momentum in this field and topped with 2706 papers in the year 2012 and the lowest just 42 in the
year 1989. The trend shows that Wind Power Generation (WPG) publications have gradually increased.
