...the whole room illuminates. But, congressman, let me ask you. Have you ever wondered how electricity works? What is it that makes electricity possible? What did it take for light to have the ability to stream out of the light bulb? We take electricity for granted, but not many of us actually look into it. People often do not know how electricity is the way it is, but instead they see electricity as something that is very accessible and plentiful. So, congressman, you have the money, and I have the brains. You want to know how to spend the 200 billion? I’ll tell you. Let’s start off with what electricity really is. You hear that word so many times in your daily life, but few have heard the scientific definition. Electricity is a type of energy produced from the existence of electrons or protons, either statically as a build-up of charge, or dynamically as a current. It is usually categorized into two different currents: alternating current (AC) and direct current (DC). Alternating current is a constant flow of electric charge that reverses its course from time to time. Direct current is the opposite; it only runs in one direction. Within those two currents are things such as volts, watts, amperes (or amps), and ohms. Volts are the SI unit of electromotive force, the distinction of potential that would force one ampere of current against one ohm resistance. A watt is also an SI unit, but unlike a volt, it is built upon power. One watt is equal to one joule per second, relating...

...ENERGY Renewable Energy: An Overview DOE/GO-102001-1102 FS175 March 2001 EFFICIENCY AND RENEWABLE ENERGY What is Renewable Energy? Renewable energy uses energy sources that are continually replenished by nature—the sun, the wind, water, the Earth’s heat, and plants. Renewable energy technologies turn these fuels into usable forms of energy—most often elec- tricity, but also heat, chemicals, or mechanical power. Why Use Renewable Energy? Today we primarily use fossil fuels to heat and power our homes and fuel our cars. It’s convenient to use coal, oil, and natural gas for meeting our energy needs, but we have a limited supply of these fuels on the Earth. We’re using them much more rapidly than they are being created. Even- tually, they will run out. And because of safety concerns and waste disposal prob- lems, the United States will retire much of its nuclear capacity by 2020. In the mean- time, the nation’s energy needs are expected to grow by 33 percent during the next 20 years. Renewable energy can help fill the gap. Even if we had an unlimited supply of fos- sil fuels, using renewable energy is better for the environment. We often call renew- able energy technologies “clean” or “green” because they produce few if any pollutants. Burning fossil fuels, however, sends greenhouse gases into the atmos- phere, trapping the sun’s heat and con- tributing to global warming. Climate scientists generally agree that the Earth’s average temperature has risen in the past century...

...FROM THE AUTHOR OF THE BESTSELLING BIOGRAPHIES OF BENJAMIN FRANKLIN AND ALBERT EINSTEIN, THIS IS THE EXCLUSIVE BIOGRAPHY OF STEVE JOBS. Based on more than forty interviews with Jobs conducted over two years—as well as interviews with more than a hundred family members, friends, adversaries, competitors, and colleagues—Walter Isaacson has written a riveting story of the roller-coaster life and searingly intense personality of a creative entrepreneur whose passion for perfection and ferocious drive revolutionized six industries: personal computers, animated movies, music, phones, tablet computing, and digital publishing. At a time when America is seeking ways to sustain its innovative edge, Jobs stands as the ultimate icon of inventiveness and applied imagination. He knew that the best way to create value in the twenty-first century was to connect creativity with technology. He built a company where leaps of the imagination were combined with remarkable feats of engineering. Although Jobs cooperated with this book, he asked for no control over what was written nor even the right to read it before it was published. He put nothing offlimits. He encouraged the people he knew to speak honestly. And Jobs speaks candidly, sometimes brutally so, about the people he worked with and competed against. His friends, foes, and colleagues provide an unvarnished view of the passions, perfectionism, obsessions, artistry, devilry, and compulsion for control that shaped his approach to business and...
