Summarizes the current status of solid-state lighting (SSL) technologies and products - light-emitting diodes (LEDs) and organic LEDs (OLEDs) - and evaluates barriers to their improved cost and performance. This title discusses factors involved in achieving widespread deployment and consumer acceptance of SSL products.

This report by the National Research Council's (NRC's) Committee on Review of the U.S. DRIVE Research Program, Phase 4, follows three previous NRC reviews of the FreedomCAR and Fuel Partnership, which was the predecessor of the U.S. DRIVE Partnership (NRC, 2005, 2008a, 2010). The U.S. DRIVE (Driving Research and Innovation for Vehicle Efficiency and Energy Sustainability) vision, according to the charter of the Partnership, is this: "American ...

The United States is responsible for nearly one-fifth of the world's energy consumption. Population growth, and the associated growth in housing, commercial floor space, transportation, goods, and services is expected to cause a 0.7 percent annual increase in energy demand for the foreseeable future. The energy used by the commercial and residential sectors represents approximately 40 percent of the nation's total energy consumption, and the s...

The scientific and technological progress in inertial confinement fusion has been substantial during the past decade. However, many of the technologies needed for an integrated inertial fusion energy system are still at an early stage of technological maturity. For all approaches to inertial fusion energy there remain critical scientific and engineering challenges. In this interim report of the study An Assessment of the Prospects for Inertial...

In 2001, the National Research Council (NRC) completed a congressionally mandated assessment of the benefits and costs of DOE's fossil energy and energy efficiency R&D, programs, Energy Research at DOE: Was It Worth It? The Congress followed this retrospective study by directing DOE to request the NRC to develop a methodology for assessing prospective benefits. The first phase of this project?development of the methodology?began in December 20...

The 21st Century Truck Partnership (21CTP), a cooperative research and development partnership was launched in the year 2000 with high hopes that it would advance the technologies used in trucks and buses, yielding a cleaner, safer, more efficient generation of vehicles. This book examines the overall adequacy and balance of the 21CTP.

The Vision 21 Program is a relatively new research and development (R&D, ) program. It is funded through the U.S. Department of Energy's (DOE's) Office of Fossil Energy and its National Energy Technology Laboratory (NETL). The Vision 21 Program Plan anticipates that Vision 21 facilities will be able to convert fossil fuels (e.g., coal, natural gas, and petroleum coke) into electricity, process heat, fuels, and/or chemicals cost effectively, wi...

In legislation appropriating funds for DOE's fiscal year (FY) 2000 energy R&D, budget, the House Interior Appropriations Subcommittee directed an evaluation of the benefits that have accrued to the nation from the R&D, conducted since 1978 in DOE's energy efficiency and fossil energy programs. In response to the congressional charge, the National Research Council formed the Committee on Benefits of DOE R&D, on Energy Efficiency and Fossil Ener...

The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual verti...

In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the secur...

In July 2010, the National Research Council (NRC) appointed the Committee to Review the 21st Century Truck Partnership, Phase 2, to conduct an independent review of the 21st Century Truck Partnership (21CTP). The 21CTP is a cooperative research and development (R&D, ) partnership including four federal agencies-the U.S. Department of Energy (DOE), U.S. Department of Transportation (DOT), U.S. Department of Defense (DOD), and the U.S. Environme...

Events and analyses have suggested that global production of oil might peak in the future. To explore this issue, the NRC held a workshop, funded by the Department of Energy. This report provides a summary of the workshop including the key points, issues and questions raised by the participants, and it identifies topics for follow-up studies.
