   a One unit is one system, appliance, or piece of equipment. The number of units is assumed to equal the number of households, except where shown.
   b Consumption per unit is assumed to equal consumption per household, except where shown.
   c Households with both central air-conditioning and individual room units are counted only under "Central."
   d Households with both main space-heating systems and secondary equipment are counted only under "Main System." 
   e Energy used to heat water coming into the washer is excluded.
   f Only those households where the most-used range top is electric and where more than one meal per week is cooked are counted.
   g Only those households where the most-used oven is electric and the oven is used more than once per week are counted.
   h Only those households where the coffee maker is used more than once per week are counted.
   i "Lighting" includes indoor and outdoor uses. Halogen torchiere lamps are not included.
   j "PC" includes desktop and laptop personal computers.  "Printer" includes printers with and without fax/copiers.
   k "Stereo" includes component and compact stereo systems and portable stereos ('boom boxes").
   l "Other End Uses" includes many end uses, such as the operation of irons, hair dryers, electric blankets, power tools, and air cleaners, not specifically listed, as well as errors that may be present in estimates of annual consumption.
  - = Not applicable.
   Notes: • Totals may not equal sum of components due to independent rounding.  • This table does not reflect the interactive effects of appliance usage, particularly in the case of interactions between appliance usage estimated from RECS data and appliance usage estimated from other sources.
