April 13th, 2009  |  Published in Energy Tips

The following list will give you an approximated AVERAGE monthly kilowatt hour usage for a variety of appliances. Energy saver models will use less and some older models will use more. Therefore, these are only approximated figures.

These figures are averages and vary according to your individual lifestyle and the energy efficiency of the appliance. For appliances not listed you can use the following to figure your monthly usage.

VOLTS X AMPS = WATTS. Normal voltage for small appliances is 120 volts.

(WATTAGE X ESTIMATED OPERATING HOURS X 30 DAYS) / 1000 kwh’s= ESTIMATED MONTHLY USAGE.
