The Truth About Energy

The transition to renewable energy is vital and fast-paced, but how do we choose which technologies to drive this energy transition? This timely book provides everyone interested in the renewable energy transition with an introduction to and technical foundation for understanding modern energy technology. It traces everyday power generation through history, from the Industrial Revolution to today. It examines the use of wood, coal, oil, natural gas, hydro, and nuclear to produce energy, before discussing renewable energy sources such as biomass, photovoltaics, concentrated solar power, wind, wave, and geothermal. The book examines to what extent and how each technology can contribute to a clean, green infrastructure. The Truth About Energy explains the science and engineering of energy to help everyone understand and compare current and future advances in renewable energy, providing the context to critically examine the different technologies that are competing in a fast-evolving engineering, political, and economic landscape.

This high-voltage introduction to energy combines physical science and environmental science with fun. Easy-to-follow diagrams show different ways energy can be harnessed. Tips on how to use energy sensibly are included.

An informed look at the myths and fears surrounding nuclear energy, and a practical, politically realistic solution to global warming and our energy needs. Faced by the world's oil shortages and curious about alternative energy sources, Gwyneth Cravens skeptically sets out to find the truth about nuclear energy. Her conclusion: it is a totally viable and practical solution to global warming. In the end, we see that if we are to care for subsequent generations, embracing nuclear energy is an ethical imperative.

Combines physical science and environmental science with fun.

Renewable Energy Principles covers the main types of sustainable power sources including Wind, Solar, Hydro, Geothermal and more. It presents current facts and truths that relate to the energy industry today.

Comical characters explain the basics, including the many forms energy can take. Readers can learn how energy changes from one form to another so that the Sun's energy can end up in a lunch box and eventually in people's muscles. Easy-to-follow diagrams show different ways energy can be harnessed. For a green look at the topic, the pros and cons of each form of energy are outlined, and tips on how to use energy sensibly are included. This high-voltage introduction to energy combines physical science and environmental science with fun.

A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

Using the principle that extracting energy from the environment always involves some type of impact on the environment, The Future of Energy discusses the sources, technologies, and tradeoffs involved in meeting the world's energy needs. A historical, scientific, and technical background set the stage for discussions on a wide range of energy sources, including conventional fossil fuels like oil, gas, and coal, as well as emerging renewable sources like solar, wind, geothermal, and biofuels. Readers will learn that there are no truly "green" energy sources—all energy usage involves some tradeoffs—and will understand these tradeoffs and other issues involved in using each energy source. Each potential energy source includes discussions of tradeoffs in economics, environmental, and policy implications Examples and cases of implementing each technology are included throughout the book Technical discussions are supported with equations, graphs, and tables Includes discussions of carbon capture and sequestration as emerging technologies to manage carbon dioxide emissions
