Renewable energy refers to a type of energy that originates from natural sources, which can be replenished more quickly than their rate of consumption. Wind energy, hydroelectric power, solar energy and geothermal energy are examples of renewable energy sources. These energy sources can augment the production of electricity, thus lowering energy costs. The effectiveness of renewable energy is determined by the resources which are utilized. Some renewable energy sources, such as wind and sunlight, are more efficient and widely available than others, whereas renewable sources of energy such as geothermal energy are available in some selected places only. The projects involving renewable energy are usually large-scale and are appropriate for remote and rural areas. This book elucidates the concepts and innovative models around prospective developments with respect to renewable energy sources. It will also provide interesting topics for research, which interested readers can take up. For all readers who are interested in the engineering and technology of renewable energy sources, the studies included in this book will serve as an excellent guide to develop a comprehensive understanding.

This book focuses on latent heat storage, which is one of the most efficient ways of storing thermal energy. Unlike the sensible heat storage method, the latent heat storage method provides much higher storage density with a smaller difference between storing and releasing temperatures.Thermal Energy Storage with Phase Change Materials is structured into four chapters that cover many aspects of thermal energy storage and their practical applications. Chapter 1 reviews selection, performance, and applications of phase change materials. Chapter 2 investigates mathematical analyses of phase change processes. Chapters 3 and 4 present passive and active applications for energy saving, peak load shifting, and price-based control heating using phase change materials.These chapters explore the hot topic of energy saving in an overarching way, and so they are relevant to all courses. This book is an ideal research reference for students at the postgraduate level. It also serves as a useful reference for electrical, mechanical, and chemical engineers and students throughout their work.FEATURESExplains the technical principles of thermal energy storage, including materials and applications in different classificationsProvides fundamental calculations of heat transfer with phase changeDiscusses the benefits and limitations of different types of phase change materials (PCM) in both micro- and macroencapsulationsReviews the mechanisms and applications of available thermal energy storage systemsIntroduces innovative solutions in hot and cold storage applications
