Alarm clock radio electricity usage

What is electricity consumption of average/common alarm clock radio?

A typical household item, alarm clock radios are used to program wake-up times to the sound of the radio or preloaded music. While some older versions or ones with plenty of extra functions can consume up to 5 watts of electricity, modern alarm clocks with built-in radios that are Energy Star certified utilize between 1 and 2 watts. A typical alarm clock radio is expected to consume 2 watts.

To determine the energy usage of a typical alarm clock radio utilizing 2 Watts for 24 hours a day at $0.10 per kWh, click calculate.

Kilowatts per dayhelp Here you will see a value for how much energy (in watts, kilowatts or megawatts) the device will consume per day if it is used for the time you specify. The formula "Hours used per day" × "Power use" is used.:

Watts Kilowatts Megawatts

Hours Used Per Day: Indicate the average number of hours per day that the device is used. If the daily power usage is less than one hour, enter the number as a decimal (for instance, 30 minutes a day equals 0.5).

Power Use (Watts): Type in the watts that represent the device's typical power use.

Price (kWh): Enter the price per kilowatt hour you pay typically; our calculators use a default value of 0.10 (10 cents). Check your power bill for the precise cost.

It would not be a terrible idea to unplug your alarm clock radio if you will be gone for a long time so that it won't consume extra energy.
