I unplugged my microwave
The Experiment
Wanting to reduce household energy use, I tested whether unplugging my microwave after each use would lower my electricity bill.
The experiment focused on standby power, or “phantom load,” which occurs when appliances consume electricity while idle.
What I Found
The microwave used about 3 watts while sitting unused, potentially adding up to roughly 26 kilowatt-hours annually.
However, after two weeks, unplugging it saved only about half a kilowatt-hour—just a few cents.
The Inconvenience
Resetting the clock every time became frustrating, while reaching the outlet was inconvenient. Although unplugging technically
reduced electricity use, the savings were too small to make much difference.
Better Ways to Save
The experiment showed that larger energy users offer greater savings. More effective strategies include using LED lighting, efficient appliances,
smart power strips, and adjusting thermostat settings. Unplugging the microwave may help, but it is “too small to justify the daily hassle for most households.”
