Does Unplugging Your Microwave Save Money? A Two-Week Test Suggests the Impact Is Minimal
A common energy-saving habit—unplugging household appliances to reduce “phantom” or standby power use—was recently tested with a focus on the microwave.
The idea behind the practice is simple: many modern appliances continue to draw small amounts of electricity even when not in active use, often to power digital clocks, standby displays, or responsive control systems. Over time, these small draws are believed to contribute to higher electricity bills.
In this case, a two-week informal test examined whether unplugging a microwave after each use would meaningfully reduce energy consumption. The findings suggested that while the appliance does use a small amount of standby power, the overall impact is minimal.
Microwaves typically consume only a few watts when idle, primarily to keep the clock running or maintain quick-start functionality. Even when extrapolated over an entire year, the total cost of this standby usage was estimated to amount to only a small amount in electricity expenses.
The results indicate that while unplugging appliances may reduce energy waste in principle, the microwave’s contribution to household electricity bills is relatively minor compared to larger energy-consuming devices.
