Abstract

The demand on energy has reached very high levels, the main reason of it, is the rapid increase of urbanization, the neighbourhoods, built environment, public transportation and services. In order to achieve energy sustainability, renewable energies must be taken into account. Among the renewable energies, wind energy is one of the most sustainable, research in this field is a crucial role for the development of a country as Mexico. This paper analyzed the contribution of Mexican institutions in literature specialized on wind during the period 1969-2016, considering complete years; 31,890 documents have been  considered. It has been used Elsevier's Scopus database and bibliographic analysis techniques, considering in the analysis all the material reported by Scopus as source type, keyword, subject area, source title, affiliation, document type, country, journal articles or conference proceedings. Data reported in Scopus have been used in this study. An analysis has been done on many different publications such as document type, language, evolution on wind research, publication distribution, Gross Domestic Product (GDP) versus document published by State, h-index and the frequency of keyword appearance. A national map showing the distribution by state and a worldwide map presenting the collaboration with international researchers.

Conclusion

An analysis of Mexican research on wind as topic during 1969-2016 have given interesting results, it has found 31,890 documents, most of them are articles (75.5%) and the most language used in the research is English (96.92%), this could be because Mexican researchers collaborate with US researcher in almost the 50% of the documents published.
