A new method of presenting the potential for conservation is discussed. Supply curves of conserved energy provide a consistent accounting framework for assessing diverse conservation measures. They also permit simple comparison of conservation measures among themselves and with conventional...

The combined energy consumption of US televisions and videocassette recorders was about 40TWh per year in 1998, corresponding to 3.6% of national residential electricity consumption. The average household television energy consumption was about 310kWh per year, 23% of which was used while the...

The rapidly changing energy situation has led to new analyses of energy conservation from both physical and economic perspectives. A physics perspective suggests that the technical prospects for improved efficiency remain very great. An economics perspective suggests that conserved energy may be...

We compared Home Energy Rating Systems (HERS) ratings and actual utility billing data for about 500 houses in four states. We found that HERS can, on average, predict annual energy cost accurately. However, on an individual house basis the agreement between predicted energy cost and actual...

About 18% of all U.S. residential electricity, or 1600 kWh/yr per household, is used for miscellaneous appliances. Such appliances include waterbeds, dehumidifiers, television sets, well pumps, and clocks. The saturations, stocks, and electricity use for 35 appliances within the miscellaneous...

As part of its acid rain program, the U.S. EPA has established a system of tradable SO2 emission allowances. The regulations also permit electric utilities to earn emission allowances through conservation programs. The utility may verify the savings with “Conservation Verification Protocols...
