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. |

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. |
