What use more power - the Clock vs the MicrowaveWhen I first heard that the Clock on a Microwave used more energy than Microwave itself in most homes, I thought, "Oh boy, another energy myth". After all, I knew that the oven uses about 1000 watts while the clock uses six. But then I thought, wait a minute, the clock is running 24 hours a day, while the oven is running just a few minutes a day. Then I did the math: How much energy the clock uses in a day: 6 (watts) x 24 (hours) = 144 (watt-hours) How long it takes the microwave to the same amount of energy: 144 watt-hours / 1000 watts = 0.14 hours, or 8.6 minutes This means that if you use a typical microwave oven for less than 9 minutes/day, the clock uses more electricity than the oven.
So it's not a myth
