"New energy power generation is crucial technology of current developing electricity generation. Due to fossil fuel is finite and unfriendly to environment while applying it as energy source; it is unsatisfactory with strategy of sustainable development. New energy power generation has had a great progress in photovoltaic generation and wind power generation. In the new energy generation technology, thermal energy can be transformed to electricity with combination of BIPV and thermal energy storage technology. Thermal energy storage in general, and phase change materials (PCMs) in particular, have been a main topic in research for the last 20 years, but although the information is quantitatively enormous, it is also spread widely in the literature, and difficult to find. Thermal Engineering offers a broad review of recent global developments in an application of thermal and thermochemical processing to modify the microstructure and properties of a wide range of engineering materials. It analyzes the current state and perspectives of energy development, design and operation of power engineering equipment such as that at thermal and nuclear power stations, energy conservation and pollution control, the theoretical fundamentals of heat engineering, and non-traditional heat sources. Applied novel research about the development and demonstration of components, equipment, technologies and systems involving thermal processes for the production, storage, utilization, and conservation of energy are also explored. This book will appeal to students, researchers, research scholars, teachers, authors and other professionals in the field of research in Thermal Engineering subjects."
