ENERGY: ITS USE AND THE ENVIRONMENT, Third Edition is an introductory textbook that emphasizes the physical principles behind energy and its effects on our environment. It can be used in physics, technology, physical science, and environmental science courses for non-science majors. Many of the standard topics found in introductory physics textbooks are included. As a result, this book can be used as the text in a conceptual physics course with energy as the central theme. Much of the pedagogy used comes from a one-semester general education course the authors have taught at State University of New York (SUNY) College at Oswego, over the past 20 years. No math or other science prerequisite is necessary.
