Our modern standard of living depends on the transformation of energy from sources like fossil fuels, atomic nuclei, the sun, and wind into usable forms. This book examines the fundamental physics behind energy use that is crucial in our daily lives.Amid widespread discussions about the potentially harmful and irreversible impact of CO₂ emissions on climate change, is the potential of renewable energy sources like solar and wind to replace fossil fuels. The Simple Physics of Energy Use 2nd Edition questions the feasibility of this transition. What does fundamental physics reveal about the practicality of this solution? Is it realistic to eliminate CO₂ emissions rather than reduce them? Inspired by modern media debate, this book provides thought-provoking problems based on real-world proposals.Examining three key aspects of energy use in modern life: environmental control in buildings, transportation of people and goods, and manufacturing, this new edition provides a comprehensive overview of the subject. It also offers an in-depth exploration of electrical power generation and the use of simple algebra provides a clear, big-picture perspective that highlights significant factors in understanding the physics of energy use. This is a key text for readers interested in the origins and applications of the energy we rely on.
