  • Of the many ages of man—the Stone Age, the Bronze Age, the Iron Age, etc.-that preceded the 1800s, and that led one into the other, none was as rewarding to mankind as the electrical age. We now stand in awe of the space age, andin fear we face the nuclear age. From electricity, however, has been drawn a n ever growing abundance o f light, power, warmth, intelligence, and medical aid-all beneficent, silent, and ready. Electricity is the one force in the arsenal of man that found no precedent in earlier history, nor was it drawn from classical times.

  • To accurately estimate energy savings attributable to the ENERGY STAR program, and target future efforts, current data are needed on the extent to which each type of office equipment is turned off or successfully enters low power mode when idle. Combined with measurements of the energy used in each power state, we can estimate typical unit energy consumption (UEC), which, combined with number of units currently in use, provides an estimate of total energy use, and program savings (Webber, Brown et al. 2002). In our ongoing technical support of ...
