The Theory of Reliability in Energy . Reliability of generation systems using wind and solar energy" edited by B. A. Tremyasova represents an important contribution to the modern understanding of the reliability of renewable energy sources. In the context of global climate change and the pursuit of sustainable development, this work is becoming especially relevant for energy professionals, engineers, students and anyone interested in new technologies in the field of ecology and energy. The book examines key aspects of the reliability of generation systems using wind and solar energy. The authors deeply analyze the factors affecting the effectiveness and durability of these systems, which makes the work valuable for both theorists and practitioners. Readers will be able to learn about methods of reliability assessment, as well as about modern approaches to the design and operation of renewable energy systems. This is particularly important in light of humanity’s growing dependence on sustainable and clean energy sources. The book will be of interest not only to professional power engineers and engineers, but also to students of technical universities, researchers, as well as anyone interested in sustainable development and ecology. If you want to understand how wind and solar power work, what problems may arise during their operation and how they can be overcome, this book will be an indispensable tool. The topics raised in the book cover a wide range of issues, including the economics of renewable energy, the impact of climate conditions on systems, and methods for forecasting and risk management. The authors not only share theoretical knowledge, but also offer practical recommendations, which makes the material available and useful for application in real conditions. The style of presentation in the book is clear and logical, which allows the reader to easily assimilate complex concepts. In. A. Tremyasov and his team of authors use many examples from practice, which makes the material more visual and understandable. This is especially important for those who are just beginning their journey in the study of energy or want to expand their knowledge in the field of renewable sources. In addition, the book "The Theory of Reliability in Energy" will be of interest to those who are already familiar with other works in the . A. Tremyasova, such as "Energy and Ecology" and "Modern Technologies in Energy". These works are also devoted to issues of sustainable development and efficient use of resources, which creates a holistic view of current trends in the energy industry. In conclusion, "The theory of reliability in the energy sector . The reliability of generation systems using wind and solar energy is not just a textbook, but a real find for everyone who seeks to understand and improve the future of energy. The book inspires new ideas and solutions, emphasizing the importance of reliability in energy systems, making it an indispensable source of knowledge for all who want to contribute to sustainable development and environmental protection.
