BestPractices Program tip sheet discussing preventive maintenance strategies for compressed air systems.

Small Wind Electric Systems: An Idaho Consumer's Guide provides consumers with information to help them determine whether a small wind electric system can provide all or a portion of the energy they need for their home or business based on their wind resource, energy needs, and their economics. Topics discussed in the guide include how to make a home more energy efficient, how to choose the correct turbine size, the parts of a wind electric system, how to determine whether enough wind resource exists, how to choose the best site for a turbine, how to connect a system to the utility grid, and whether it's possible to become independent of the utility grid using wind energy. In addition, the cover of the guide contains a regional wind resource map and a list of incentives and contacts for more information.

NREL's International & Environmental programs work to bring renewable energy technologies to developing nations, and to improve health, local economies, community development, and the environment. These programs provide expertise throughout the world in rural energy, integrated resource assessment, technology options analysis, training on renewable energy topics, renewable energy policy assistance, greenhouse gas mitigation, clean energy technology transfer, rural electrification, and air quality protection.

An assessment team conducted a pinch analysis on major production processes at a Rohm and Haas chemical plant. Several potential projects were identified, which could yield annual savings totaling 2.2 million MMBtu and almost$7.7 million.

This paper reviews the current status of the commercial PV Industry. It assesses the current status of commercially available modules, most of which use silicon wafers or ribbons. My analysis will show that the choice of Si wafers or substrates, once deemed to be the most important aspect, ended up making only negligible differences for commercial products, as long as cells are prepared by diffusion and screen printing. I will also address the prospects and requirements for both next generation thin-film modules and super-high (>20%) efficient commercial crystalline Si cells. It is shown that traditional recombination loss analyses provide a poor tool for understanding limitations of cell and module performance, because those analytical schemes ignore dominating interactions between different loss mechanisms (e.g., of surface and bulk recombination).

Summary of AMCAST Industrial Corporation's plant-wide assessment to identify energy and cost saving opportunities at the corporation's facility in Wapakoneta, Ohio.

The primary focus of this work is a new adaptive controller that is designed to resemble the standard non-adaptive controller used by the wind industry for variable speed wind turbines below rated power. This adaptive controller uses a simple, highly intuitive gain adaptation law designed to seek out the optimal gain for maximizing the turbine's energy capture. It is designed to work even in real, time-varying winds.

Future solar photovoltaics-hydrogen systems are discussed in terms of the evolving hydrogen economy. The focus is on distributed hydrogen, relying on the same distributed-energy strengths of solar-photovoltaic electricity in the built environment. Solar-hydrogen residences/buildings, as well as solar parks, are presented. The economics, feasibility, and potential of these approaches are evaluated in terms of roadmap predictions on photovoltaic and hydrogen pathways-and whether solar-hydrogen fit in these strategies and timeframes. Issues with the ''hydrogen future'' are considered, and alternatives to this hydrogen future are examined.

This subcontract report describes how Energy Conversion Devices, Inc., has developed and built 7 generations of roll-to-roll amorphous silicon PV production equipment. In the ECD/United Solar production process, we deposit about a 1-mm-thick, 12-layer coating consisting of a metal/oxide backreflector, a 9-layer a-Si/a-SiGe alloy triple-junction solar cell, and top transparent conductive oxide coating onto 125-mm-thick, 35.5-cm-wide stainless-steel webs in a series of three roll-to-roll deposition machines. In the PV Manufacturing R&D 6 program, ECD is building upon these accomplishments to enhance the operation of the present production machine, and lay the foundation for improvements in the next-generation machine. ECD has completed the Phase I work for the first two Tasks, and will complete the Phase I work for the second two tasks within the next two months. In the following report, we summarize the Phase I work in each of these tasks. We have involved United Solar production personnel in each of these Tasks. This is important for two reasons: First, the collaboration of ECD and United Solar personnel keeps the projects responsive to the developing needs at United Solar; and most of the tasks affect operations and consequently need the support of United Solar production and QA/QC managers.

Due to the development of the solar energy industry, a significant increase of polysilicon feedstock (PSF) production will be required in near future. The creation of special technology of solar grade polysilicon feedstock production is an important problem. Today, semiconductor-grade polysilicon is mainly manufactured using the trichlorosilane (SiHCl3) distillation and reduction. The feed-stock for trichlorosilane is metallurgical-grade silicon, the product of reduction of natural quartzite (silica). This polysilicon production method is characterized by high energy consumption and large amounts of wastes, containing environmentally harmful chlorine based compounds. In the former USSR the principles of industrial method for production of monosilane and polycrystalline silicon by thermal decomposition of monosilane were founded. This technology was proved in industrial scale at production of gaseous monosilane and PSF. We offered new chlorine free technology (CFT). Originality and novelty of the process were confirmed by Russian and US patents.
