1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt.

Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant.

So...

To calculate the kilowatt hours:

.1 kilowatts (from above, knowing the energy use of the bulb)

Multiplied by 24 hours in a day

Multiplied by 30 days...

.1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours
