Where does the energy we use come from? It's absolutely vital to every single thing we do every day, but for most people, it is utterly invisible. Flick a switch and the lights go on. It might as well be magic. Science writer Jeremy Shere shows us in Renewable: The World-Changing Powerof Alternative Energy that energy is anything but magical. Producing it in fossil fuel form is a dirty, expensive—but also hugely profitable— enterprise, with enormous but largely hidden costs to the entire planet. The cold, hard fact is that at some point we will have wrung the planet dry of easily accessible sources of fossil fuel. And when that time comes, humankind will have no choice but to turn—or, more accurately, return—to other, cleaner, renewable energy sources. What will those sources be? How far have we come to realizing the technologies that will make these sources available? To find the answers, Shere began his journey with a tour of a traditional coal-fueled power plant in his home state of Indiana. He then continued on, traveling from coast to coast as he spoke to scientists, scholars and innovators. He immersed himself in the green energy world: visiting a solar farm at Denver's airport, attending the Wind Power Expo and a wind farm tour in Texas, investigating turbines deep in New York City's East River, and much more. Arranged in five parts—Green Gas, Sun, Wind, Earth, and Water—Renewable tells the stories of the most interesting and promising types of renewable energy: namely, biofuel, solar, wind, geothermal, and hydropower. But unlike many books about alternative energy, Renewable is not obsessed with megawatts and tips for building home solar panels. Instead, Shere digs into the rich, surprisingly long histories of these technologies, bringing to life the pioneering scientists, inventors, and visionaries who blazed the way for solar, wind, hydro, and other forms of renewable power, and unearthing the curious involvement of great thinkers like Henry Ford, Thomas Edison, and Nicola Tesla. We are at an important crossroads in the history of renewable technologies. The possibilities are endless and enticing, and it has become increasingly clear that renewable energy is the way of the future. In Renewable, Jeremy Shere's natural curiosity and serious research come together in an entertaining and informative guide to where renewable energy has been, where it is today, and where it's heading.

This timely book explores proven and emerging solutions for building a global green energy economy as a basis for a prosperous and yet sustainable world. Only a world based on continuous renewal can sustain life and livelihoods. This book shares many examples and proposals for: accelerating the renewable energy revolution; renewing the world's ecosystems and soils; renewing cities and local economies; and invigorating international cooperation.

The World Renewable Energy Congress is a key event at the start of the 21st century.It is a vital forum for researchers with an interest in helping renewables to reach their full potential. The effects of global warming and pollution are becoming more apparent for all to see - and the development of renewable solutions to these problems is increasingly important globally.If you were unable to attend the conference, the proceedings will provide an invaluable comprehensive summary of the latest topics and papers.

A comprehensive political analysis of the rapid growth in renewable wind and solar power, mapping an energy transition through theory, case studies, and policy. Wind and solar are the most dynamic components of the global power sector. How did this happen? After the 1973 oil crisis, the limitations of an energy system based on fossil fuels created an urgent need to experiment with alternatives, and some pioneering governments reaped political gains by investing heavily in alternative energy such as wind or solar power. Public policy enabled growth over time, and economies of scale brought down costs dramatically. In this book, Michaël Aklin and Johannes Urpelainen offer a comprehensive political analysis of the rapid growth in renewable wind and solar power, mapping an energy transition through theory, case studies, and policy analysis. Aklin and Urpelainen argue that, because the fossil fuel energy system and political support for it are so entrenched, only an external shock—an abrupt rise in oil prices, or a nuclear power accident, for example—allows renewable energy to grow. They analyze the key factors that enable renewable energy to withstand political backlash, andt they draw on this analyisis to explain and predict the development of renewable energy in different countries over time. They examine the pioneering efforts in the United States, Germany, and Denmark after the 1973 oil crisis and other shocks; explain why the United States surrendered its leadership role in renewable energy; and trace the recent rapid growth of modern renewables in electricity generation, describing, among other things, the return of wind and solar to the United States. Finally, they apply the lessons of their analysis to contemporary energy policy issues.

This volume focuses on a few renewable energy sources, viz. wind energy plus energy from water movement and natural temperature differences that in principle could provide enormous energy resources. Energy from wind has been a rapidly growing source of energy as wind turbines have grown in size and especially as wind turbines have moved offshore. Hydroelectric dams have continued to be used as energy sources particularly in developing countries. Other energy sources using water, including waves and tidal sources, are also discussed in this volume. Finally, the volume discusses differences between deep and surface ocean temperatures plus the extraction of energy from the earth's extremely large energy resource of magma deep below the surface. These latter two energy resources in particular require further development and the current book describes the latest advances coupled with pointing possible paths forward.

Making local energy futures, from marine energy to hydrogen fuel, at the edge of the world. The islands of Orkney, off the northern coast of Scotland, are closer to the Arctic Circle than to London. Surrounded by fierce seas and shrouded by clouds and mist, the islands seem to mark the edge of the known world. And yet they are a center for energy technology innovation, from marine energy to hydrogen fuel networks, attracting the interest of venture capitalists and local communities. In this book, Laura Watts tells a story of making energy futures at the edge of the world. Orkney, Watts tells us, has been making technology for six thousand years, from arrowheads and stone circles to wave and tide energy prototypes. Artifacts and traces of all the ages—Stone, Bronze, Iron, Viking, Silicon—are visible everywhere. The islanders turned to energy innovation when forced to contend with an energy infrastructure they had outgrown. Today, Orkney is home to the European Marine Energy Centre, established in 2003. There are about forty open-sea marine energy test facilities in the world, many of which draw on Orkney expertise. The islands generate more renewable energy than they use, are growing hydrogen fuel and electric car networks, and have hundreds of locally owned micro wind turbines and a decade-old smart grid. Mixing storytelling and ethnography, empiricism and lyricism, Watts tells an Orkney energy saga—an account of how the islands are creating their own low-carbon future in the face of the seemingly impossible. The Orkney Islands, Watts shows, are playing a long game, making energy futures for another six thousand years.

The book looks at water availability and water demand in various sectors till 2050, presenting a methodology to prioritize options both on the demand and on the supply side, with a special focus on renewable energy desalination.
