Obstacles and opportunities in the commercialization of the solid-state-electronic fluorescent-lighting ballast
The Solid State Ballast (SSB) Program, aimed at improving the efficiency of fluorescent lights, is described. The first generation of solid state electronic ballasts has been developed and the technology has been transferred to the private sector. This report examines the opportunities for rapid dissemination of this technology into the marketplace. It includes a description of product characteristics and their influence on the commercialization of the SSB, a description of the technology delivery system presently used by the ballast industry, an analysis of the market for SSB, and identification of some high-leverage opportunities to accelerate the commercialization process.

Environmental characterization of two potential locations at Hanford for a new production reactor
This report describes various environmental aspects of two areas on the Hanford Site that are potential locations for a New Production Reactor (NPR). The area known as the Skagit Hanford Site is considered the primary or reference site. The second area, termed the Firehouse Site, is considered the alternate site. The report encompasses an environmental characterization of these two potential NPR locations. Eight subject areas are covered: geography and demography; ecology; meteorology; hydrology; geology; cultural resources assessment; economic and social effects of station construction and operation; and environmental monitoring. 80 refs., 68 figs., 109 tabs
Challenges for energy efficiency improvement under the CDM -the case of energy-efficient lighting
The CDM under the Kyoto Protocol has so far been unable to mobilize activities of households and service industries to improve end-use energy efficiency. This is mainly due to the lack of or the cumbersome requirements of the few existing baseline and monitoring methodologies as well as the difficulty to prove project additionality. We assess methodologies for projects distributing compact fluorescent lamps to households. The approval of the first large-scale methodology took more than 2 years and in the interaction with the regulatory bodies, the methodology became very cumbersome, especially regarding monitoring requirements. Four sample groups are required and the technology that has to be used for measuring utilization of CFLs does not yet exist. Therefore, project developers are not applying the large-scale methodology but try to use the pre-defined small-scale methodology. But even the small-scale methodology requires a substantial amount of data and measurements. A “Programme of Activity” approach could reduce monitoring costs through limiting monitoring to a sample of projects. Moreover, monitoring experts could be trained and thus monitoring mistakes reduced compared to single project settings. A deemed savings methodology was recently approved which alleviates but does not completely eliminate monitoring needs. It considerably reduces CER volumes compared to the other two methodologies and thus project developers have to assess the trade-off between higher monitoring costs and lower CER volumes
