This book was released on 2017-06-11 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard incandescent light bulb, which still works mainly as Thomas Edison invented it, converts more than 90% of the consumed electricity into heat. Given the availability of newer lighting technologies that convert a greater percentage of electricity into useful light, there is potential to decrease the amount of energy used for lighting in both commercial and residential applications. Although technologies such as compact fluorescent lamps (CFLs) have emerged in the past few decades and will help achieve the goal of increased energy efficiency, solid-state lighting (SSL) stands to play a large role in dramatically decreasing U.S. energy consumption for lighting. Since the publication of the 2013 National Research Council report Assessment of Advanced Solid-State Lighting, the penetration of SSL has increased dramatically, with a resulting savings in energy and costs that were foreshadowed by that study. What was not anticipated then is the dramatic dislocation and restructuring of the SSL marketplace, as cost reductions for light-emitting diode (LED) components reduced profitability for LED manufacturers. At the same time, there has been the emergence of new applications for SSL, which have the potential to create new markets and commercial opportunities for the SSL industry. Assessment of Solid-State Lighting, Phase Two discusses these aspects of changeâ€"highlighting the progress of commercialization and acceptance of SSL and reviewing the technical advances and challenges in achieving higher efficacy for LEDs and organic light-emitting diodes. This report will also discuss the recent trends in SSL manufacturing and opportunities for new applications and describe the role played by the Department of Energy (DOE) Lighting Program in the development of SSL.

Download or read book The Power of Change written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-30 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity, supplied reliably and affordably, is foundational to the U.S. economy and is utterly indispensable to modern society. However, emissions resulting from many forms of electricity generation create environmental risks that could have significant negative economic, security, and human health consequences. Large-scale installation of cleaner power generation has been generally hampered because greener technologies are more expensive than the technologies that currently produce most of our power. Rather than trade affordability and reliability for low emissions, is there a way to balance all three? The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies considers how to speed up innovations that would dramatically improve the performance and lower the cost of currently available technologies while also developing new advanced cleaner energy technologies. According to this report, there is an opportunity for the United States to continue to lead in the pursuit of increasingly clean, more efficient electricity through innovation in advanced technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies makes the case that America's advantagesâ€"world-class universities and national laboratories, a vibrant private sector, and innovative states, cities, and regions that are free to experiment with a variety of public policy approachesâ€"position the United States to create and lead a new clean energy revolution. This study focuses on five paths to accelerate the market adoption of increasing clean energy and efficiency technologies: (1) expanding the portfolio of cleaner energy technology options; (2) leveraging the advantages of energy efficiency; (3) facilitating the development of increasing clean technologies, including renewables, nuclear, and cleaner fossil; (4) improving the existing technologies, systems, and infrastructure; and (5) leveling the playing field for cleaner energy technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies is a call for leadership to transform the United States energy sector in order to both mitigate the risks of greenhouse gas and other pollutants and to spur future economic growth. This study's focus on science, technology, and economic policy makes it a valuable resource to guide support that produces innovation to meet energy challenges now and for the future.

Download or read book Prospective Evaluation of Applied Energy Research and Development at DOE Phase One written by National Research Council and published by National Academies Press. This book was released on 2005-06-27 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 projectâ€"development of the methodologyâ€"began in December 2003. Phase two will make the methodology more robust and explore related issues, and subsequent phases will apply the methodology to review the prospective benefits of different DOE fossil energy and energy efficiency R&D programs. In developing this project, three considerations were particularly important. First, the study should adapt the work of the retrospective study. Second, the project should develop a methodology that provides a rigorous calculation of benefits and risks, and a practical and consistent process for its application. Third, the methodology should be transparent, should not require extensive resources for implementation, and should produce easily understood results. This report presents the results of phase one. It focuses on adaptation of the retrospective methodology to a prospective context.
Download or read book Solid State Lighting written by Timothy Lee Kelly and published by . This book was released on 2004 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining an understanding of the technical progress and potential of semiconductor light emitting materials with an analysis of market adoption reveals useful insights into challenges and opportunities in the growing field of solid state lighting. The integration of discrete LEDs into solid state lighting systems is identified as a critical area of both technical and business development and the key to creating useful products and expanding new markets. Analysis of conventional and emerging optosemiconductor lighting industries highlights important differences of influence within the value chain. For solid state lighting, the significance of system integration shifts control away from large LED manufacturers and closer to the end user. Special focus on companies pursuing the system integrator role compares strategies for technology based niche players with strategies for joint venture companies formed by alliances of large lighting and semiconductor companies. Based on technology capability, industry conditions, and historical analogy, solid state lighting is projected to achieve wider adoption primarily through the growth of new applications and markets, not through the substitution of existing lighting business.
