Many people unplug appliances when they are not in use, believing it helps reduce electricity bills. But does this habit actually make a difference?
The answer is yes—although the amount you save depends on the type of device and how often it remains plugged in.
What Is Phantom Energy?
Even when turned off, many electronic devices continue to draw a small amount of electricity. This is often called:
- Phantom power
- Standby power
- Vampire energy
These devices remain partially active so they can perform functions such as:
- Displaying clocks
- Maintaining settings
- Responding to remote controls
- Staying connected to networks
Over time, this small energy use can add up.
Common Devices That Use Electricity While Turned Off
Many household items continue consuming power when not actively being used, including:
- Televisions
- Cable boxes
- Game consoles
- Computers
- Printers
- Coffee makers with digital displays
- Microwaves with clocks
- Phone chargers left plugged in
Individually, the consumption may seem minor, but together they can contribute to higher energy bills.

How Much Can You Save?
The savings vary depending on:
- The number of devices in your home
- Their standby power consumption
- Local electricity rates
Homes with many electronics may notice greater savings by reducing unnecessary standby power.
While unplugging everything won’t eliminate your electricity bill, it can help lower energy waste.
Devices Worth Unplugging
The biggest energy-saving opportunities often come from:
Entertainment Systems
Televisions, streaming devices, speakers, and gaming consoles frequently remain in standby mode.
Computer Equipment
Desktop computers, monitors, printers, and accessories can consume electricity even when idle.
Kitchen Appliances
Some appliances with digital displays draw power continuously.
Chargers
Phone and laptop chargers may continue drawing small amounts of electricity when left plugged into outlets.
Devices That Can Stay Plugged In
Certain appliances generally use very little standby power or are designed to remain connected, including:
- Refrigerators
- Freezers
- Routers and internet equipment
- Security systems
- Medical devices
These should typically remain plugged in unless instructed otherwise by the manufacturer.
An Easier Alternative
Instead of unplugging devices one by one, many people use power strips.
With a single switch, multiple devices can be disconnected from power when not in use.
This approach is convenient and may help reduce standby energy consumption.
Additional Benefits
Reducing unnecessary power use can:
- Lower electricity bills
- Reduce energy waste
- Decrease environmental impact
- Protect some electronics from power surges
These benefits can make unplugging certain devices a worthwhile habit.
Common Myths
Myth: Everything uses large amounts of electricity when off.
Most devices use only small amounts of standby power. However, multiple devices combined can create noticeable energy consumption.
Myth: Unplugging will dramatically reduce your bill overnight.
Savings are typically gradual and depend on your home’s electronics and usage habits.
Myth: Chargers use huge amounts of power when not connected.
Most modern chargers use very little electricity when left plugged in, though unplugging them can still eliminate unnecessary consumption.
