Appliance Energy Use and Costs |
|
|
|
|
|||||
|
This fact
sheet provides information about the energy use and associated energy costs
of common home appliances. The average costs are based |
|||||||||
|
on NH average electric rate of $0.136 per kWh. Listed wattages are
averages only; wattage on your individual appliances may vary. |
|||||||||
|
|
|
|
|
|
|||||
|
For
example, an electric wall heater having 1500 Watts of power, on continuously
for 4 hours, would use 6000 Watt hours of energy, |
|||||||||
|
or stated in kilowatt hours, 6 kWh, multiplied by the rate $0.136 equals
the cost. |
