Solar Energy and Its Global Investments (original) (raw)

This study aimed to analyze the research about solar energy on a global scale over the past five years, in order to identify the way to apply this source of energy and which countries are participating in the solar area investigation. In this context the scientific journals publications on solar energy of the last five years (2010-2015) were analyzed, focusing on renewable energies and as selection criteria, the Impact Factor (IF) was adopted. The articles were analyzed in a summarized manner for a sample population of over 350 publications, from which the IF index ranged from 3 to 15. The results show that in the whole world the countries with the highest number of publications in the solar energy field are India, China, Spain, Malaysia and the United States, totaling more than half of the worldwide research. Solar thermal energy had an increasing participation in the polls and the year 2014 got the highest number of publications linked to solar energy in the world.
