The Journal of Renewable Energies is an open access journal, which means all its content is freely available without charge on the principle that making research freely available to the public supports a greater global exchange of knowledge. The authors can submit their works without processing charge (APC). Also, the public is allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the publisher or the author as long as they cite the source. The only constraint on reproduction and distribution, and the only role for copyright in this domain, should be to give authors control over the integrity of their work and the right to be properly acknowledged and cited.
