This book presents both the importance of energy transition and its associated difficulties. Providing an explanation of the physical concepts of energy and power, the book reviews global energy consumption and our dependence on energy. It discusses the links between the economy and energy. It explains the drawbacks and dangers of different energy sources and tries to compare them.Reviewing future energy resources, it evaluates several transition scenarios.It shows that the laws of physics prevent the emergence of simple and pleasant solutions.It proposes potential solutions and encourages the reader to develop better processes, from energy sources to production, to consumption.The book will be of interest to engineers and undergraduate and graduate students studying and working in various fields of energy, producers of fossil, gas, oil, coal, electric, renewable and nuclear energy, as well as all the curious people who are interested in better understanding these fundamental problems for our future.Features•Discusses the current issues with energy transition•Covers several energy transition scenarios and associated difficulties•Presents the links between economy and energy•Highlights the importance of a global discussion of energy•Encourages the development of better, improved processes in energy sources, from production to consumption.
