Without a doubt, the topic of energy--from coal, oil, and nuclear to geothermal, solar and wind--is one of the most pressing across the globe. It is of paramount importance to policy makers, economists, environmentalists, and industry as they consider which technologies to invest in, how to promote use of renewable energy sources, and how to plan for dwindling reserves of non-renewable energy. InEnergy: What Everyone Needs to Know, Jos Goldemberg, a nuclear physicist who has been hailed byTimemagazine as one of the world's top "leaders and visionaries on the environment," takes readers through the basics of the world energy system, its problems, and the technical as well as non-technical solutions to the most pressing energy problems. Addressing the issues in a Q-and-A format, Goldemberg answers such questions as: What are wind, wave, and geothermal energy? What are the problems of nuclear waste disposal? What is acid rain? What is the greenhouse gas effect? What is Carbon Capture and Storage? What are smart grids? What is the Kyoto Protocol? What is "cap and trade"? The book sheds light on the role of population growth in energy consumption, renewable energy resources, the amount of available energy reserves (and when they will run out), geopolitical issues, environmental problems, the frequency of environmental disasters, energy efficiency, new technologies, and solutions to changing consumption patterns. It will be the first place to look for information on the vital topic of energy.
