Liquid Refrigerant Pumping Incorporating Superheat Suppression in Commercial Refrigeration Systems for Capacity Boosts and Energy Savings Liquid refrigerant pumping technology has given refrigeration systems capacity boosts while saving electrical energy. Using this technology, liquid refrigerant entering the liquid line is pressurized by a small centrifugal pump. The pressurized amount is equivalent to the pressure loss between the receiver and the thermostatic expansion valve (TEV) inlet. By increasing the pressure of liquid refrigerant, the associated saturation temperature is raised, while the actual liquid temperature remains the same. The liquid therefore becomes subcooled and will not flash if exposed to pressure drops in the liquid line.
Log Homes and Energy Efficiency Log homes may be hand-made on-site or pre-cut in a factory for delivery to the site. Pre-cut log home kits have been produced since 1923. Log home manufacturers can also customize their designs. Wall thickness' range from 6-16 inches (152-406 millimeters [mm]). The log industry enthusiastically promotes the energy efficiency of log buildings. While there is general agreement on the aesthetic value of log homes, their energy efficiency is disputed.
Low Cost Energy Efficiency Programs This study, performed by Pacific Energy Associates (PEA) and The Regulatory Assistance Project (RAP), was undertaken to determine through empirical research the relative success of utility energy efficiency programs with a track record, and that are compatible with a competitive industry. By “compatible with a competitive industry” we mean that they are low cost or have no cost to the sponsoring utility or government entity, yet are effective in saving energy and offering customers desired services. Our focus was on commercial and industrial energy efficiency programs.

Land, Energy and Water: The Constraints Governing Ideal U.S. Population Size An article by David Pimentel and Marcia Pimentel. This is the third of a series of NPG FORUM papers exploring the idea of optimum population. Taken together the papers constitute a cross-disciplinary study of carrying capacity in relation to many variables. The issues raised by the authors of the series are interesting, thought provoking, even frightening, but most of all crucial to national policies. Without any consensus as to whether our population should be larger or smaller, decisions we are making as a nation create our demographic and resource future.
Lighting Research Center (LRC) The Lighting Research Center (LRC) is part of the School of Architecture at Rensselaer Polytechnic Institute. It was formed in 1988 with the goal of changing architecture, through lighting that is energy efficient and responsive to human needs. This web site features links to other lighting resources on the web, descriptions of the LRC's research projects, a catalog of lighting publications, and information for students interested in the LRC's Master of Science in Lighting graduate degree program. Visitors can also request free publications and subscribe to a free newsletter on new lighting technologies, Lighting Futures.
Low Cost Energy Efficiency Programs - Summary This study, performed by Pacific Energy Associates (PEA) and The Regulatory Assistance Project (RAP), was undertaken to determine through empirical research the relative success of utility energy efficiency programs with a track record, and that are compatible with a competitive industry. By “compatible with a competitive industry” they mean that they are low cost or have no cost to the sponsoring utility or government entity, yet are effective in saving energy and offering customers desired services. Their focus was on commercial and industrial energy efficiency programs.
Low Cost Passive and Hybrid Solar Retrofits Solar Energy systems don't have to be complicated or expensive to do an effective job of saving energy. The familiar active systems and their associated hardware - pumps, thermostats, rooftop collectors, etc. - represent only one method of converting a home to solar heat. There are simpler and cheaper alternatives. Passive solar systems, unlike active solar systems, require no significant mechanical equipment and operate without any external power. Instead, they rely on natural heat movement through convection, conduction and radiation.

National Conservation Guild It is the purpose of the National Conservation Guild to promote energy conservation technologies, financing programs and products to energy comsumers. Since 1973 a core of energy conservation conscious consumers and programs have provided the financial foundation upon which technologies and products have been developed and improved. A perusal of this website will provide many examples. The National Conservation Guild provides a forum/marketplace that consumers and Journalists can utilize to keep abreast of these developments. The Guild website also offers a showplace for energy conservation innovations to be displayed. Profits provided from sales through the Guild are used to further spread the news of these developments.
National Energy Audit (NEAT) Software National Energy Audit (NEAT) software was developed at ORNL for DOE's Weatherization Assistance Program, which provides funds for installing energy efficiency measures in the homes of low-income families with children, the elderly, and people with disabilities. In 1995 NEAT is being used by about 500 local agencies in 30 states to make retrofitting decisions for more than 80,000 low-income, single-family dwellings. Several electric and gas utilities have adopted it for demand-side management programs to reduce consumption of and peak demands for electricity and natural gas.
National Energy Conservation Association (NECA) The National Energy Conservation Association (NECA) is a nonprofit, industry organization championing energy conservation in buildings and fostering a professional and profitable industry environment.

NEGAWATT POWER: The Cost and Potential of Electrical Efficiency Resources in Western Europe By Florentin Krause (Principal Investigator), David Olivier & Jonathan Koomey. The present report points to another economic prize that is equally large or larger, but at risk of being forgotten. This prize is found in the enormous potential for using electricity more efficiently, both in a technical and in an economic sense. These so-called negawatt resources exist because the markets for energy efficiency suffer from pervasive problems of high transaction cost.
