The Journal of Energy Systems aims to publish high quality research and review papers on energy systems design and implementation. The submitted materials must fulfill the conditions of being innovative, sustainable and practical information to make an impact on the society of energy engineering. The novel research may cover experimental practices, theoretical studies or both of them. The journal promotes the contributions of academic and technical bodies from especially the interdisciplinary research groups, thereby new ideas can be discussed in a scientific manner. Journal of Energy Systems is indexed in Scopus and EBSCO Academic Search Ultimate International, open-access, peer-reviewed journal.
