This two-page performance spotlight describes how, in 2003, Kodak's facilities in Rochester, New York, significantly improved the energy efficiency of its two lake-water pumping stations to save more than $100,000 annually in energy and maintenance costs. The project reduced energy use by more than 1 million kilowatt-hours per year and allowed fewer pumps to operate at any one time, while maintaining previous pumping performance levels. A U.S. Department of Energy Qualified Pumping System Assessment Tool Specialist at Flowserve Corporation assisted in the initial system assessment that resulted in this project.

A Clean Cities publication regarding the National Partner Award winners announced at the 2004 Clean Cities Conference.

Reverse Osmosis (RO) is a method of purifying water for industrial processes and human consumption; RO can remove mineral salts as well as contaminants such as bacteria and pesticides. Advances in water treatment technologies have enhanced and complemented the conventional RO process, reducing energy and water consumption, lowering capital and operating costs, and producing purer water. This publication of the Department of Energy's Federal Energy Management Program introduces RO, describes the benefits of high-efficiency reverse osmosis (HERO), and compares HERO with RO/electrodeionization (EDI) technology.

This guide describes the general use, input file formatting, compilation and execution of the STOMP (Subsurface Transport Over Multiple Phases) simulator, a scientific tool for analyzing single and multiple phase subsurface flow and transport. A description of the simulator's governing equations, constitutive functions and numerical solution algorithms are provided in a companion theory guide. In writing these guides for the STOMP simulator, the authors have assumed that the reader comprehends concepts and theories associated with multiple-phase hydrology, heat transfer, thermodynamics, radioactive chain decay, and relative permeability-saturation-capillary pressure constitutive relations. The authors further assume that the reader is familiar with the computing environment on which they plan to compile and execute the STOMP simulator. The STOMP simulator requires an ANSI FORTRAN 77 compiler to generate an executable code. The memory requirements for executing the simulator are dependent on the complexity of physical system to be modeled and the size and dimensionality of the computational domain. Likewise execution speed depends on the problem complexity, size and dimensionality of the computational domain, and computer performance.

This fact sheet recognizes the 2003 Clean Cities National Partner Award winners and their outstanding efforts to promote alternative fuels and alternative fuel vehicles.

In the ongoing discussion of what needs to be done to stabilize atmospheric CO2 by mid-century (Hoffert 1998), one possible option would be to add about 10-20 terawatts (trillion watts, or TW) of photovoltaics (PV) in place of conventional sources. PV would help because, unlike burning fossil fuels, it produces no CO2. However, 10-20 TW is an enormous amount of energy. In peak Watts, the way PV installations are generally rated, it is about 50-100 TWpeak (TWp) of PV. Would we have enough materials to make this much PV? As we explain in this PV FAQ, we think our planet has enough feedstock materials for PV to meet the ''TW challenge.''

The cover of this guide contains the results of the 2003 National Corn Producer Survey Wind Energy Issues.

In August 2004, the San Jose Mercury News, a Knight-Ridder company, upgraded the compressed air system at its printing facility in California. Before the upgrade, the compressed air system had been performing erratically and energy costs were on the rise. Therefore, the Mercury News commissioned a system-level evaluation of the compressed air system by Air Perfection, a U.S. Department of Energy Allied Partner. The evaluation estimated potential energy savings and suggested improvements, which the plant carried out. The result is a compressed air system that performs better and saves energy because of better compressor control, fewer leaks, more stable pressure levels, and improved air treatment.

This document assists federal agencies in incorporating emissions market opportunities in their energy projects, including emission reduction credit markets and cap and trade. It looks at how potential emissions costs/revenues can be incorporated into project proposals, how groups can apply for emissions allowances, and how agencies can sell emissions allowances and receive the financial benefit. The fact sheet also outlines how FEMP can provide assistance throughout the process.

This handbook describes the assembly and operation of an enhanced Modified Faraday Cup (MFC) diagnostic device for measuring the power density distribution of high power electron beams used for welding. The most recent version of this diagnostic device, [1] Version 2.0, contains modifications to the hardware components of previous MFC designs.[2] These modifications allow for more complete capture of the electrons and better electrical grounding, thus improving the quality of the acquired data and enabling a more accurate computed tomographic (CT) reconstruction [3,4] of the power density distribution of the electron beam to be performed.
