  basic electricity principles: Freeing Energy: How Innovators Are Using Local-scale Solar and Batteries to Disrupt the Global Energy Industry from the Outside In Bill Nussey, 2021-11-05 The transition to clean energy is moving far too slowly. Trapped by a century of fossil fuel investments and politicians that struggle to plan beyond the next election, the Big Grid that powers our modern world is outdated and in dire need of an upgrade. Freeing Energy offers a new and faster path towards a clean energy future-one that is more reliable, more equitable, and cheaper. Just like personal computers eclipsed mainframes, millions of solar rooftops and small battery systems are challenging every assumption about our century-old, centralized electric grid. These small-scale local energy systems are deeply disruptive because they are based on fast-moving technologies, not fuels. Driven by a new generation of innovators and genuinely competitive markets, smaller systems are faster to build, easier to finance, cleaner to operate, and they create far more jobs than large-scale projects. Bill Nussey takes readers to mud huts in Africa, an off-grid farm in California, and a rural school in the mountains of Puerto Rico to uncover the underlying patterns of technology and the business model innovations of the local energy revolution. He shares stories and insights from some of the industry's brightest visionaries and from leaders of the most cutting-edge startups, bringing it all together into an actionable framework to help accelerate this transition. Freeing Energy is a deeply researched, actionable guide for anyone that cares about the future of energy-from startups, policymakers, investors, and utility leaders to the families and communities that want cleaner, cheaper energy today.

  basic electricity principles: Electrical Engineering Fundamentals S. Bobby Rauf, 2020-12-17 Many, in their quest for knowledge in engineering, find typical textbooks intimidating. Perhaps due to an extensive amount of physics theory, an overwhelming barrage of math, and not enough practical application of the engineering principles, laws, and equations. Therein lies the difference between this text and those voluminous and daunting conventional university engineering textbooks. This text leads the reader into more complex and abstract content after explaining the electrical engineering concepts and principles in an easy to understand fashion, supported by analogies borrowed from day-to-day examples and other engineering disciplines. Many complex electrical engineering concepts, for example, power factor, are examined from multiple perspectives, aided by diagrams, illustrations, and examples that the reader can easily relate to. Throughout this book, the reader will gain a clear and strong grasp of electrical engineering fundamentals, and a better understanding of electrical engineering terms, concepts, principles, laws, analytical techniques, solution strategies, and computational techniques. The reader will also develop the ability to communicate with professional electrical engineers, controls engineers, and electricians on their wavelength with greater confidence. Study of this book can help develop skills and preparation necessary for succeeding in the electrical engineering portion of various certification and licensure exams, including Fundamentals of Engineering (FE), Professional Engineering (PE), Certified Energy Manager (CEM), and many other trade certification tests. This text can serve as a compact and simplified electrical engineering desk reference. This book provides a brief introduction to the NEC®, the Arc-Flash Code, and a better understanding of electrical energy and associated cost. If you need to gain a better understanding of myriad battery alternatives available in the market, their strengths and weaknesses, and how batteries compare with capacitors as energy storage devices, this book can be a starting point. This book is ideal for engineers, engineering students, facility managers, engineering managers, program/project managers, and other executives who do not possess a current working knowledge of electrical engineering. Because of the simple explanations, analogies, and practical examples employed by the author, this book serves as an excellent learning tool for non-engineers, technical writers, attorneys, electrical sales professionals, energy professionals, electrical equipment procurement agents, construction managers, facility managers, and maintenance managers.

Basic principles and methods Alauddin Khan, Shumsun Naher Begum, 2021-01-21 Document from the year 2020 in the subject Physics - General, grade: 4.00, , language: English, abstract: The book is intended as a text book on Electricity and Magnetism for undergraduate levels students of Physics and also as a reference book for anyone who is interested in this field of enquiry. This volume demanded such as to explain the physical concepts, to describe the mathematical formalism, and to present illustrative examples of both the ideas and the methods of Electricity and Magnetism. The book comprehensively discusses all topics that are usually taught to upper undergraduate students of Physics. Written for general physics courses this text deals with large-scale phenomena and then proceeds to small-scale less accessible phenomena. Examples of calculations are presented after important formulas are derived, and actual related experiments are explained in detail. Sometimes, students were facing serious obstacles in their learning process due to their unavoidable situations and lack of previous background study of Electricity and Magnetism. This book will help the students alike who have no previous much study of Electricity and Magnetism. It is written such that the basic understanding of Electricity and Magnetism is conveyed to the students without any difficulty. Also teachers of courses on Electricity and Magnetism can use this book as their own lecture plans without any modification. It is to be noted that the purpose of this book is to cover the basic principles and methods of Electricity and Magnetism which are usually included in the course of teaching Physics at the undergraduate levels student. I hope this book will be useful to the students and teachers in the different universities around the world.
