A component in the America's Energy Future study, Electricity from Renewable Resources examines the technical potential for electric power generation with alternative sources such as wind, solar-photovoltaic, geothermal, solar-thermal, hydroelectric, and other renewable sources. The book focuses on those renewable sources that show the most promise for initial commercial deployment within 10 years and will lead to a substantial impact on the U.S. energy system. A quantitative characterization of technologies, this book lays out expectations of costs, performance, and impacts, as well as barriers and research and development needs. In addition to a principal focus on renewable energy technologies for power generation, the book addresses the challenges of incorporating such technologies into the power grid, as well as potential improvements in the national electricity grid that could enable better and more extensive utilization of wind, solar-thermal, solar photovoltaics, and other renewable technologies.

This volume examines the outlook for renewable energy in electricity generation-particularly wind and solar power-as a substitute for conventional fuels such as coal and natural gas. Economist Benjamin Zycher evaluates the central arguments in favor of policies that would make way for broader use of renewables and concludes that all are deeply problematic. "Renewable" energy sources are not superior in cost to conventional fuels; nor are they less taxing on the environment. The popular argument that increased use of renewables will create "green jobs" is likewise a fallacy-because wind and solar power are costly and inefficient, the net economic impact is a negative one. Zycher concludes that resource-use behaviors emerging from market competition are the best guides to effective, sustainable energy policies.

This textbook is about economically competitive renewable energy sources (RES), including onshore and offshore wind, solar and small-hydro plants, and focusing on the electricity production from these sources. Clearly divided into sections discussing the different RES, the textbook begins with an introduction of AC electrical circuits, aimed at non-electrical engineers. It then offers an economic assessment of renewable energy projects, before discussing photovoltaic technologies and concentrated solar power. It explores the theory of wind to power conversion, electrical generator types and electrical part of offshore systems. Presenting theoretical concepts related to the electrical framework associated with RES, alongside examples and solved problems, this book will clearly introduce the topic of renewable power sources to graduate students, researchers and practitioners alike. After reading the book, readers will be equipped to make a preliminary techno-economic assessment of a RES.

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.

Hydrogen and fuel cells are vital technologies to ensure a secure and CO2-free energy future. Their development will take decades of extensive public and private effort to achieve technology breakthroughs and commercial maturity. Government research programs are indispensable for catalyzing the development process. This report maps the IEA countries' current efforts to research, develop and deploy the interlocking elements that constitute a "hydrogen economy", including CO2 capture and storage when hydrogen is produced out of fossil fuels. It provides an overview of what is being done, and by whom, covering an extensive complexity of national government R & D programs. The survey highlights the potential for exploiting the benefits of the international cooperation. This book draws primarily upon information contributed by IEA governments. In virtually all the IEA countries, important R & D and policy efforts on hydrogen and fuel cells are in place and expanding. Some are fully-integrated, government-funded programs, some are a key element in an overall strategy spread among multiple public and private efforts. The large amount of information provided in this publication reflects the vast array of technologies and logistics required to build the "hydrogen economy."--Publisher description.

Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.

A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.
