SEGA believes that long-term sustainable development can only be achieved if sustainable energy and green architecture are considered together. Through full research papers and compact reviews covering all applications of science and technology, the journal bridges the crucial gap between basic research and inventions, targeting a broad audience of academic and industrial researchers, as well as the increasingly important world of scientists and engineers at start-up companies. The journal provides a forum for scientists and engineers, physicists, and chemists to communicate on the most important topics in the fields of sustainable energy and green architecture. There is also a space to advertise sustainable products, new technologies, green design and urban planning. SEGA invites full research and compact reviews covering all applications of science and technology paper on (but not limited to) the following topics:
