Clock radio (in use)

"Clock radio (in use)" is the amount of time that you are listening to the radio. For example, if you use a clock radio for 2 hours every day, please enter "2" in the first field and select "hours/day" in the second field. Your cost per month and cost per year will be automatically calculated.

Clock radios continue to use energy when they are not "in use" (to power the clock). To calculate this cost, please use the "Clock radio (stand-by)" section.
