Abstract(s)
Desde a década de 1970, tem-se verificado um aumento nos estudos relacionados com a
utilização de fontes de energia renovável, em especial a energia eólica, devido à necessidade
de reduzir os impactos ambientais dos combustíveis fósseis. Inicialmente estes estudos
estavam restritos a sistemas de energia eólica utilizando torres e aerogeradores. No entanto,
atualmente observa-se um interesse na tecnologia emergente, como os sistemas aéreos de
produção de energia eólica.
Desta forma realizou-se uma análise bibliométrica entre 1996 e junho de 2023 sobre a
energia eólica e tecnologia emergente combinando métodos quantitativos e qualitativos na
análise exploratória das produções científicas sobre estes temas, disponíveis em língua
inglesa e portuguesa. Das diversas fontes existentes optou-se por só utilizar o motor de
pesquisa “Google Scholar”, devido à sua capacidade de realizar pesquisas abrangentes em
produções científicas, incorporando resultados de outros mecanismos de procura.
Antes de iniciar a pesquisa, definiu-se as palavras-chave a utilizar, limitou-se a quantidade
de produções científicas a analisar e estabeleceu-se quais os elementos a considerar na
análise bibliométrica. Assim, para este estudo o tamanho da amostra é de 500 publicações
em língua inglesa e 100 em língua portuguesa, nas quais foram posteriormente analisadas
quanto às suas interconexões, correlações, distribuição geográfica e o número de citações.
Para a análise das correlações recorreu-se ao software VOSviewer.
Com base na amostra analisada, observou-se que o número de publicações científicas sobre
energia eólica tradicional, em ambas as línguas, apresentou uma tendência de crescimento
de 1996 a 2013, seguida por uma queda acentuada a partir de 2013. No que diz respeito às
produções científicas associadas aos sistemas aéreos de geração de energia eólica, notou-se
um crescimento significativo no número de publicações a partir de 2013.
Conclui-se também que, no caso da energia eólica tradicional em língua inglesa, os Estados
Unidos da América destacam-se como o país com o maior número de autores de produções
científicas e também com a maior quantidade de publicações em revistas. No que se refere
aos sistemas aéreos de geração de energia eólica, considerados como tecnologia emergente, observa-se que a Holanda lidera em termos de autores, embora as publicações sejam
predominantemente realizadas em revistas dos Estados Unidos da América.
Since the 1970s, there has been an increase in studies related to the use of renewable energy sources, especially wind energy, due to the need to reduce the environmental impacts of fossil fuels. Initially these studies were restricted to wind energy systems using towers and wind turbines. However, there is currently an interest in emerging technology, such as airborne wind energy systems. In this way, a bibliometric analysis was carried out between 1996 and June 2023 on wind energy and emerging technology, combining quantitative and qualitative methods in the exploratory analysis of scientific productions on these topics, available in English and Portuguese. Of the various existing sources, we chose to only use the “Google Scholar” search engine, due to its ability to carry out comprehensive searches in scientific productions, incorporating results from other search engines. Before carrying out the search, keywords to be used were defined, the number of scientific productions to be searched was also defined, as well as which items should be registered. Given the wide variety of scientific productions, registration was limited to 500 productions in English and 100 productions in Portuguese and analysed according to their interconnection, correlation, geographic distribution and number of citations. Using the Vosviewer software, the correlation between registered publications was analysed. Based on the analysed sample, it was observed that the number of scientific publications on traditional wind energy, in both languages, showed a growing trend from 1996 to 2013, followed by a sharp drop from 2013 onwards. Scientific productions associated with airborne wind energy systems, there was a significant increase in the number of publications from 2013 onwards. It is also concluded that, in the case of traditional wind energy in English, the United States of America stands out as the country with the largest number of authors of scientific productions and also with the largest number of publications in magazines. With regard to airborne wind energy systems, considered an emerging technology, it is observed that the Netherlands leads in terms of authors, although publications are predominantly carried out in magazines in the United States of America.
