It might seem silly but I always unplug my microwave when it’s not in use.

A while back, I plugged my microwave into my Kill-a-Watt meter and found it was using 2 1/2 watts per hour, when the microwave was off to power the clock and controls 24-7. 60 watt hours a day, doesn’t sound like a lot but there are 365 days a year, and that works out to be nearly 22 kW/h a year.

At 15 cents a kilowatt hour, that’s $3.30 a year. Not a real big expense, but every little thing adds up. Not to mention the carbon emissions, the pollution from the extraction of coal, uranium and natural gas to spin the turbines.

Not a lot, but electricity isn’t free and unplugging the microwave isn’t a lot of work.
