"Energy is, without a doubt, the very foundation of the universe. It's the engine that powers life and fuels the evolution of human civilization. Yet for all its importance, what energy really is and how it works remains a mystery to most non-scientists. For example: Where does most of our energy come from, and how is it sourced? How do energy technologies, both primitive and cutting-edge, generate power? How do we store energy--and will there be enough to meet our future needs? What are the pros and cons behind the forms of energy currently available to us? How might we harness potential future energy sources such as earthquakes and supervolcanoes? All too often, the answers to questions like these are bogged down in polemics and controversy. Imagine, then, how these and other questions could be discussed from a purely factual, scientific perspective. The truth is, to better put into perspective the various issues surrounding energy in the 21st century, you need to understand the essential science behind how energy works. And you need a reliable source whose focus is on giving you the facts you need to form your own educated opinions" -- provided by publisher.
