Best Practices in the Petroleum Industry
Nicholas P. Cheremisinoff and Paul Rosenfeld
This is the first in a series of volumes (Handbook of Pollution Prevention and Cleaner Production) on cleaner production and pollution prevention. The intent of the series is to provide guidance on best practices, technologies, and approaches to managing environmental aspects. Best Practices in the Petroleum Industry provides an overview of cleaner production methods, technologies, and practices for refineries and gas plant operations. The key environmental aspects are illustrated by case studies of major incidents that have resulted in catastrophic releases of oil and refined products, with a critical assessment of the methodology and calculation procedures that the industry relies on when preparing emissions inventories. The authors offer alternative approaches to providing more accurate emissions estimates, and guidelines on cleaner production and pollution prevention practices for improving overall environmental performance.

School Operations and Maintenance: BEST PRACTICES FOR CONTROLLING ENERGY COSTS (PDF file)
This guidebook helps K-12 school system business officials and facilities managers integrate energy efficiency into school building operation and maintenance. It also identifies common energy-efficient strategies that have been proven successful in a wide variety of American schools. Princeton Energy Resources International prepared this guidebook in collaboration with the Alliance to Save Energy and HPowell Associates, under a grant from the U.S. Department of Energy, EnergySmart Schools. The Guidebook has been very well received in the K-12 schools community and there has been a tremendous demand for the document at conferences and workshops.

On the web, the Guidebook is being marketed as a companion piece to the Energy Design Guidelines for High Performance Schools and with other K-12 school decision-maker peices. The Guidebook is also available for download from the Department of Energy, Rebuild America website at and the Association of School Business Officials International website at

Operational Constraints and Economic Benefits of Wind-Hydro Hybrid Systems: Analysis of Systems in the U.S./Canada and Russia (PDF)
There is an increasing recognition of benefits from the synergy of wind-hydro, especially in cold weather climates, but little analysis has been performed to quantify the extent of these benefits. In addition, each location presents a unique set of technical and economic conditions that significantly affect results. This paper, presented at the European Wind Energy Conference, in Madrid, Spain (June 16-19, 2003) reviews current experience with such systems, and recent analysis and data that examines and quantifies potential benefits. The paper also highlights the factors that should be considered to perform a comprehensive assessment of the benefits from such systems.

Assessment of The Commercial Potential For Small Gasification Combined Cycle and Fuel Cell Systems Phase II Final Draft Report (PDF)
A project recently completed for the U.S. Department of Energy, Office of Coal and Power Systems, reviews the status of gasification technology and assesses the potential for integration with fuel cell and gas turbine systems for small-scale (less than 50MW) power generation applications. The report also recommends R&D activities for accelerating commercial acceptance of small-scale integrated coal-gasification systems.

Waste-To-Energy and Renewable Energy Projects in Central and Eastern Europe (PDF)
PERI recently completed an assignment for USTDA identifying a pipeline of renewable and waste-to-energy projects for USTDA feasibility study grants. Selected projects were presented by project sponsors at a USTDA Conference in Prague, Czech Republic in December 2002. Mr. Rezaiyan, PERI's Vice President, also made a presentation at the conference discussing the trends in the renewable and waste-to-energy industry.

Preserving the U.S. Department of Energy, Geothermal R&D Program Legacy
November 15, 2003

It is clear to many users that U.S. geothermal technical publications and data, and citations to them, are broadly scattered among a number of different libraries. The libraries are maintained by the federal government in generalized collections, at the Department of Energy's National Laboratories; a library maintained by the main U.S. geothermal energy association, the Geothermal Resources Council (GRC); and libraries maintained by individual firms and consultants in the geothermal industry.

Geothermists have produced a large amount of literature over the past 25 years. Because of declines in the rate of geothermal system development by industry and large reductions in government funding for geothermal research, the impetus for using and extending many of the studies and reports has declined since the late 1980's. Today, many collections are being hidden in closets, shifted from place to place, discarded, or simply lost.

The Office of Geothermal Technologies at the Department of Energy (DOE) Washington Headquarters asked PERI to conduct a brief survey of where the technical literature developed by the DOE Geothermal Research Program has ended up, how to find it, and what broad steps might be useful to ensure that important information remains accessible. This research has yielded the following two reports. Click on the links below to view the reports.

  1. Preserving the Geothermal R&D Legacy: E-Archiving 25 Years of U.S. DOE Research (PDF)
    This 2003 report discusses possible methods for improving the availability of a great deal of technical information about U.S. geothermal resources and technologies that has resulted from government-sponsored research on geothermal energy since 1974. This document assesses the problems facing preserving legacy information, including identifying and selecting significant reports to preserve, harvesting the reports, developing/utilizing a repository system, and providing online access to the reports.

    Note: This is the report we would like you to review if you are participating in the PERI survey to nominate geothermal reports for long-term archiving and electronic retrieval.

    If you would like to support our efforts preserving the U.S. Geothermal R & D Legacy, please download and complete our survey. You can access the survey by clicking on this link: geothermal-survey.doc. You must save the survey to your hard drive. Once you have completed the survey, attach the file in an email addressed to Dr. Dan Entingh at We appreciate your insight and support.

  2. Geothermal Studies and Analyses. Report 6A. Status of DOE Geothermal Technical Report Collections (PDF)
    This 2002 paper was the initial survey for beginning to make sense out of what has been done, and the approaches the U.S. geothermal energy community might take in the future, for preserving documents and reports that are valuable to the entire geothermal community. It has many leads to useful collections and indexes of geothermal technical reports.
