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.
Renewable Power Pathways is the result of a study by the National Research Council (NRC) Committee for the Programmatic Review of the Office of Power Technologies (OPT) review of the U.S. Department of Energy's (DOE) Office of Power Technologies and its research and development (R&D) programs. The OPT, which is part of the Office of Energy Efficiency and Renewable Energy, conducts R&D programs for the production of electricity from renewable energy sources. Some of these programs are focused on photovoltaic, wind, solar, thermal, geothermal, biopower, and hydroelectric energy technologies; others are focused on energy storage, electric transmission (including superconductivity), and hydrogen technologies. A recent modest initiative is focused on distributed power-generation technologies. This report reviews the activities of each of OPT's programs and makes recommendations for OPT as a whole and major recommendations for individual OPT programs.
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.
Sustainability is a new, important discourse aimed at promoting a new strategy in the development of energy, water and environmental (EWE) systems — the key components that affect the quality of life on our planet. It is becoming increasingly clear that the quest for sustainable development requires integrating economic, social, cultural, political and ecological factors. The behavior and properties of an EWE system arise not merely from the properties of its component elements, but also to a large degree also from the nature and intensity of their dynamic interlinkages. This volume helps clarify the complexity of these problems by providing a deeper understanding of the implications of the different aspects of sustainability.This work contains a collection of selected, peer-reviewed and state-of-the-art reflecting papers that were presented at the Third Dubrovnik Conference on Sustainable Development of Energy, Water and Environment Systems that was held in June 5-10, 2005 in Dubrovnik, Croatia.
This report is a guidebook to help airports understand renewable energy opportunities. The report includes instructions and tools to evaluate proposed renewable energy projects and their alternatives so that an informed decision that maximizes financial, self-sustainability, environmental, and social benefits can be reached. The report lays out what a business case is, why renewable energy is important, and what a business case for renewable energy looks like. It describes the importance of identifying the project objective and understanding how renewable energy might fit into an airport’s vision. A decision-making matrix is included that contains criteria used to evaluate a renewable energy project with a system for weighting each factor based on an airport’s particular objectives. The report presents a business case in the context of an airport’s typical master planning and capital improvement planning processes including engagement of key stakeholders. The report provides a model business case that evaluates a solar photovoltaic facility, a fossil fuel generator, and a fuel cell as options for providing on-site electricity generation to improve an airport’s energy stability and resiliency. It also includes examples of renewable energy business cases from both aviation and non-aviation organizations to highlight lessons learned. A sample request for proposals and a sample power purchase agreement are provided for project implementation. A CD-ROM (CRP-CD-177) provides supplemental information.
