In 2000, the Corning glass plant in Greenville, Ohio, consumed almost 114 million kWh of electricity and nearly 308,000 MMBtu of natural gas in its glassmaking processes for a total cost of approximately $6.4 million. A plant-wide assessment indicated that improvement projects could save nearly $26 million and reduce natural gas use by 122,900 MMBtu per year, reduce electrical use by 72,300,000 kWh per year, and reduce CO2 emissions by 180 million pounds per year.

This PV FAQ fact sheet answers the question ''How much land will PV need to supply our electricity?'' The answer is that PV could supply our electricity with little visible impact on our landscape.

How long does a PV system have to operate to recover the energy-and the associated generation of pollution and CO2- that went into making the system? Energy paybacks for rooftop systems range from 1 to 4 years, depending on the system. Based on models and real data, the idea that PV cannot pay back its energy investment is simply a myth.

This PV FAQ fact sheet discusses whether we will have enough of the feedstock materials used for energy-significant PV production. The answer is that, for a set amount of PV production, we will indeed have enough materials.

This publication charts a 5-year planning cycle for the U.S. Department of Energy Solar Energy Technologies Program. The document includes anticipated technical plans for the next 5 years for photovoltaics, concentrating solar power, solar water and space heating, solar hybrid lighting, and other new concepts that can take advantage of the solar resource. Solar energy is described as a clean, abundant, renewable energy resource that can benefit the nation by diversifying our energy supply.

This report updates the 1999 economic analysis of NREL's photobiological hydrogen production from Chlamydomonas reinhardtii. The previous study had looked mainly at incident light intensities, batch cycles and light adsorption without directly attempting to model the saturation effects seen in algal cultures. This study takes a more detailed look at the effects that cell density, light adsorption and light saturation have on algal hydrogen production. Performance estimates based on actual solar data are also included in this study. Based on this analysis, the estimated future selling price of hydrogen produced from algae ranges $0.57/kg to $13.53/kg.

The Weirton Steel Corporation performed a plant-wide energy assessment of its steel mill plant in Weirton, West Virginia. Based on the assessment results, the company found strong economic justification for six projects that would reduce the use of fossil fuel, electrical energy, and water. All of the projects would save fossil fuel either for heating steam or firing the furnace. This savings totals 108,300 million British thermal units (MMBtu) annually or $1.27 million. Other yearly savings include 119 million gallons of water ($87,110) and 84,000 kilowatt-hours (kWh) or $3,357 of electrical energy. All of the projects could be applied to other steel mills and possibly other industries using steam processes and furnaces.

Fact sheet compares emissions testing of Dual-Fuel liquefied natural gas (LNG) and diesel Los Angeles Bureau of Sanitation refuse trucks, performed by DOE's Advanced Vehicle Testing Activity.

Results of a Next Generation Natural Gas Vehicle engine research project: A Caterpillar C-12 natural gas engine with Clean Air Power Dual-Fuel technology and exhaust gas recirculation demonstrated low NOx and PM emissions.

This publication is one of a series of case studies of energy-efficient modern laboratories; it was prepared for''Laboratories for the 21st Century,'' a joint program of the Environmental Protection Agency and the U.S. Department of Energy Federal Energy Management Program. It is intended for those who plan, design, and construct public and private-sector laboratory buildings. Because of its many energy-efficient and environmental features-such as natural ventilation, daylighting, and high-efficiency heating and cooling equipment and fume hoods-Bren Hall at the University of Santa Barbara, California, received a Platinum rating (the highest) in 2003 through the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program.

This report summarizes the results of a lifecycle assessment of a renewable hydrogen production process employing wind/electrolysis. Resource consumption, energy requirements, and emissions were determined in a cradle-to-grave manner on the operations required to transform raw materials into useful products, including the material production processes required to construct the wind turbines, electrolyzer, and hydrogen storage tanks.

Partnering for Success features the R & D and industrial energy management best practices and accomplishments of manufacturers who are partnering with DOE.

This trifold brochure is especially for visitors to the SERF who are viewing the PV Manufacturing R&D project display cases.

HOMER, the micropower optimization model, helps users to design micropower systems for off-grid and grid-connected power applications. HOMER models micropower systems with one or more power sources including wind turbines, photovoltaics, biomass power, hydropower, cogeneration, diesel engines, cogeneration, batteries, fuel cells, and electrolyzers. Users can explore a range of design questions such as which technologies are most effective, what size should components be, how project economics are affected by changes in loads or costs, and is the renewable resource adequate.
