Residential Miscellaneous Electricity
Historically, residential energy and carbon saving efforts have targeted conventional end uses such as water heating, lighting and refrigeration. The emergence of new household appliances has transformed energy use from a few large and easily identifiable end uses into a broad array of "miscellaneous" energy services. Miscellaneous electricity is a diverse end use category which includes household appliances such as TVs, VCRs, waterbed heaters, and even electric toothbrushes.
We use industry shipment data, lifetimes, and wattage and usage estimates of over 90 individual products to construct a bottom-up end use model (1976-2010). The model is then used to analyze historical and forecasted growth trends, and to identify the largest individual products within the miscellaneous end use.
We also use the end use model to identify and analyze policy priorities. In 1995, miscellaneous electricity accounted for about one fifth of residential electricity use, 235 TWh. From 1996-2010, we project that miscellaneous electricity will account for 90% of all future residential electricity growth, 115 TWh. Consumer electronics and halogen torchiere lamps are forecasted to account for 70% of miscellaneous growth.
Approximately 20% of miscellaneous electricity is consumed while appliances are in standby mode. Nearly all of standby consumption is attributed to consumer electronic product types. Surprisingly, about half of all consumer electronics energy is actually consumed while the products are technically "off".
About $1 billion, Ëœ20 TWh, could be saved in the U.S. annually if existing technology were applied to all household appliances that "leak" electricity. An additional 20 TWh of annual savings can be achieved by replacing halogen torchieres with compact fluorescent lamps developed in 1996 by Berkeley Lab researchers.
