Some approximate values are given in the table below regarding to power
consumption of the household appliances. The values of power consumption for
these appliances might actually be varied from these figures. The consuming
power is generally measured in the units of watt-hours. The value of power
consumption for any appliance is mostly given on the tags of the appliances.
However, it can also be calculated by multiplying the average hours used in a
day with the following given values. In this way, value of the power
consumption per day in watt-hours can considerably be measured.
Some items for example coffee maker and blender are generally used daily
for only the part of an hour. A 600-watt household appliance utilized for 5
minutes per day consumes 50 watt-hour per day. Lower and upper ranges are given
for some appliances. Lower limit is considered to be for the technologically
developed and more efficient models of appliances. The power consumption for
some home appliances is denoted with “NA” which might be due to the
non-electric sources.

* TV’s,VCR’s and other
devices left plugged in, but not turned on, still draw power.
**To estimate the number of hours that a refrigerator actually operates at its maximum wattage, divide the total time the refrigerator is plugged in by three. Refrigerators, although turned "on" all the time, actually cycle on and off as needed to maintain interior temperatures. |
