This major report analyzes the potential for electricity conservation in seven residential end uses?refrigerating, freezing, water heating, lighting, central air conditioning, cooking, and clothes drying. The analysis is based on the Pacific Gas and Electric Company service territory. It explores the costs and savings of a range of new, energy-efficient technologies including some in the prototype stage, such as heat pump and microwave clothes dryers, bi-radiant ovens, evacuated panel refrigerator insulation, and low temperature dishwashers. The authors, develop three alternative scenarios of energy demand through 2005, documenting the potential for up to 56% reduction in peak power demand and 44% reduction in electricity consumption. Prepared for the Pacific Gas and Electric Company, the report is relevant for any utility or government program planner.
