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 Power of 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.

The Regional Economic Communities (RECs) in Eastern and Southern Africa have been at the forefront to developing new energy policies and programmes aimed at reaching the UN goal of Ensuring Access to Clean Energy for All by 2030. In the year 2006, the East African Community passed the EAC Strategy to Scale Up Access to Modern Energy Services, committing its Member States to reach the UN goal of "access to all" by 2030. The Inter-governmental Authority for Development adopted its Environmental and Natural Resources Policy in 2007 which includes issues of renewable energy. The Common Market for Eastern and Southern Africa launched its Model Energy Programme in 2012, followed the same year by its comprehensive baselines database on renewable resources covering all its Member States. In the year 2009, the African Union General Assembly at its 12th Ordinary Session adopted the Policy on "Scaling Up Renewable Energy in Africa". The regional policies have been domesticated by Member Sates of the RECs. Although their targets are very ambitious, implementation programmes launched at national level are robust and producing results. Both in the policies and implementation programmes, gender issues have, however, not featured prominently. Noting this deficit, the Organisation for Social Science Research in Eastern and Southern Africa called for researchers to assess the extent to which energy policies in Eastern and Southern Africa have taken gender issues on board. This book is the product of that project. It has ten chapters that investigated the gender-energy nexus in Zimbabwe, Ethiopia, Tanzania, Swaziland, Sudan and Kenya. The book will prove useful to all policy makers, researchers and analysts who may be interested in strengthening the gender content of the programmes as we move towards 2030. We believe it triggers and helps policy makers and researchers to create platforms to use its findings, and those of others, to see how in gender terms those at the bottom of the energy access pyramid can be factored into these programmes, to make sure they are not left behind.

Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless -- every hour the sun beams down more energy than the world uses in a year. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim. Innovation can brighten those prospects, Sivaram explains, drawing on firsthand experience and original research spanning science, business, and government. Financial innovation is already enticing deep-pocketed investors to fund solar projects around the world, from the sunniest deserts to the poorest villages. Technological innovation could replace today's solar panels with coatings as cheap as paint and employ artificial photosynthesis to store intermittent sunshine as convenient fuels. And systemic innovation could add flexibility to the world's power grids and other energy systems so they can dependably channel the sun's unreliable energy. Unleashing all this innovation will require visionary public policy: funding researchers developing next-generation solar technologies, refashioning energy systems and economic markets, and putting together a diverse clean energy portfolio. Although solar can't power the planet by itself, it can be the centerpiece of a global clean energy revolution. A Council on Foreign Relations Book

Energy for Sustainability is the first undergraduate textbook on renewable energy and energy efficiency with a unique focus on the community scale. Written by two of the foremost experts in the field, it is a pedagogically complete treatment of energy sources and uses. It examines the full range of issues—from generating technologies to land use planning—in making the transition to sustainable energy. The book begins by providing a historical perspective on energy use by human civilizations and then covers energy fundamentals and trends; buildings and energy; sustainable electricity; sustainable transportation and land use; and energy policy and planning. Included in these topical areas are in-depth discussions of all of the most promising sources of renewable energy, including solar photovoltaic systems, wind turbines, and biofuels. In addition, the authors offer a thorough presentation of "green” building design, the impact of land use and transportation patterns on energy use, and the policies needed to transform energy markets at the local, state, and national levels. Throughout, the authors first provide the necessary theory and then demonstrate how it can be applied, utilizing cutting-edge practices and technologies, and the most current available data. Since the dawn of the industrial age, the explosive growth in economic productivity has been fueled by oil, coal, and natural gas. World energy use nearly doubled between 1975 and 2005. China's energy use has been doubling every decade. The implications for the environment are staggering. One way or another, our reliance on fossil fuels will have to end. Energy for Sustainability evaluates the alternatives and helps students understand how, with good planning and policy decisions, renewable energy and efficiency can support world demands at costs we can afford—economically, environmentally, and socially.

While solar is the fastest-growing energy source in the world, key concerns around solar power’s inherent variability threaten to de-rail that scale-up . Currently, integration of intermittent solar resources into the grid creates added complication to load management, leading some utilities to reject it altogether, while other operators may penalize the producers via rate increases or force solar developers to include storage devices on-site to smooth out power delivery at the point of production. However these efforts at mitigation unfold, it is increasingly clear to parties on all sides that energy storage will be pivotally important in the drive to boost the integration of variable renewable sources into power infrastructures across the globe. Thoughtfully implemented storage technologies can reduce peak demand, improve day-to-day reliability, provide emergency power in case of interrupted generation, reduce consumer and utility costs by easing load balance challenges, decrease emissions, and increase the amount of distributed and renewable energy that makes it into the grid. While energy storage has long been an area of concern for scientists and engineers, there has been no comprehensive single text covering the storage methods available to solar power producers, which leaves a lamentable gap in the literature core to this important field. Solar Energy Storage aims to become the authoritative work on the topic, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications, and emphasizing the latest technological developments driving this discipline forward. Expert contributing authors explain current and emergent storage technologies for solar, thermal, and photovoltaic applications. Sheds light on the economic status of solar storage facilities, including case studies of the particular challenges that solar energy systems present to remote locations. Includes information on: chemical storage mechanisms, mechanical storage tactics, pumped hydro, thermal storage, and storage strategies for systems of all sizes—from centralized utilities to distributed generation.

The United States and China are the world's top two energy consumers and, as of 2010, the two largest economies. Consequently, they have a decisive role to play in the world's clean energy future. Both countries are also motivated by related goals, namely diversified energy portfolios, job creation, energy security, and pollution reduction, making renewable energy development an important strategy with wide-ranging implications. Given the size of their energy markets, any substantial progress the two countries make in advancing use of renewable energy will provide global benefits, in terms of enhanced technological understanding, reduced costs through expanded deployment, and reduced greenhouse gas (GHG) emissions relative to conventional generation from fossil fuels. Within this context, the U.S. National Academies, in collaboration with the Chinese Academy of Sciences (CAS) and Chinese Academy of Engineering (CAE), reviewed renewable energy development and deployment in the two countries, to highlight prospects for collaboration across the research to deployment chain and to suggest strategies which would promote more rapid and economical attainment of renewable energy goals. Main findings and concerning renewable resource assessments, technology development, environmental impacts, market infrastructure, among others, are presented. Specific recommendations have been limited to those judged to be most likely to accelerate the pace of deployment, increase cost-competitiveness, or shape the future market for renewable energy. The recommendations presented here are also pragmatic and achievable.

Renewable Energy Technologies: Their Applications in Developing Countries presents an overview and assessment of technologies for energy-related projects in the rural sector of developing countries. This book discusses the important, but not dominant, role that new and renewable sources of energy (NARSE) will have in the Third World. Bioenergy fuel sources come from wood fuel, energy crops, agricultural residue and organic wastes, peat, biomass briquettes, biogas, and animal power. The text also describes the problems related to operating biomass engines and to the production of engine fuels such as alcohol fuels, vegetable oil, producer gas made from wood and charcoal. These problems concern land use and site location for growing these fuel crops, government policies or subsidies, as well as competition with prevailing petrol prices. Solar water heaters and photovoltaic cells can be used by households and in bigger institutions; ongoing technological developments mainly focus on cutting down costs and better manufacturing methods. The book also addresses other NARSE such as hydro, wind, and water power generation. This book is suitable for economists, environmentalists, ecologists, and policy makers involved in energy conservation and rural development.
