Post-face and pedagogical suggestions

The book is covering three major disciples: basic and fundamental knowledge in power systems, such as power engineering basic and foundations, motors and transformers, power distribution basic, second the building and industrial power distribution, such as load characteristics and calculations, load and motor centers, building electrical systems and lighting, and motor protection and control, and the third fundamentals of the major renewable energy sources and energy storage, such as solar and wind energy, photovoltaics, geothermal energy and small hydro-power systems, major energy storage technologies, and a brief description of microgrids, distributed generation issues and energy management. Due to the fast pace of changes into the energy sectors and uses, more and more professional and the fresh graduates in the industrial and engineering fields, and not only are required to have better understanding of the energy industries, energy supply issues, energy conservation, alternative energy sources, or sustainability.
