It’s a fact that essential home appliances such as televisions, computers, electric stoves, and microwaves continue to draw power if they’re not unplugged from the socket. These appliances are often the “culprits” behind high monthly electricity bills, even if you try to reduce your usage.

The simplest way to address this issue is to unplug appliances as soon as you’ve finished using them. According to the US Department of Energy, this practice can help an average household save up to $100 (over 2 million VND) a year.

Why does unplugging save electricity?

Many people mistakenly believe that turning off appliances means they’re no longer using electricity. In reality, these appliances continue to consume standby power even when they’re turned off but still plugged in. There are four common reasons for this:

– Some devices use a small amount of electricity to power indicator lights or displays.

– Computers are in sleep mode instead of being completely shut down.

– Chargers continue to draw power even after the device is detached.

– New-generation smart home appliances, such as washing machines, dryers, and refrigerators with always-on displays and internet connectivity, consume electricity even when not in use.

Unplug when not in use

How to avoid wasting money on unused electrical appliances

The first step is to remember to unplug appliances that aren’t being used. However, this can be inconvenient, especially if the outlet is in an awkward location, as is often the case in modern homes.

In such cases, you can take a more proactive approach by setting up automatic power shut-off systems:

– Use a power strip (a strip with multiple outlets): The advantage of this type of power strip is that it has its own power button, allowing you to turn off multiple devices at once with ease.

– Smart timer: You can use a smart timer or smart plug to remotely turn off appliances when they’re not in use.

Summary

Frequently asked questions

Silent energy vampires refer to household appliances that continue to draw power even when they’re switched off or in standby mode. Over time, the cumulative energy consumption of these appliances can significantly increase your electricity bills. Examples of such appliances include TVs, set-top boxes, game consoles, computers, phone chargers, and kitchen appliances with digital displays.

To identify silent energy vampires, you can use a power meter to measure the energy consumption of your appliances. Plug the appliance into the power meter, which is then plugged into the wall outlet. The power meter will display the amount of energy being used, even when the appliance is turned off. Look for appliances that consistently draw a notable amount of power.

To reduce their impact, unplug appliances when they’re not in use, or use power strips and remember to switch them off. This completely cuts the power supply to the appliances. Another option is to look for energy-efficient appliances with a low standby power consumption. You can also consider smart power strips that automatically cut power to appliances when they’re not in use.

Yes, certain appliances are notorious for being silent energy vampires. These include older appliances that don’t have energy-efficient features, as well as devices with external power supplies or those that use a remote control. Appliances with ‘instant-on’ functionality often continuously draw power to enable quick startup.

The amount of savings can vary depending on the number of silent energy vampires in your home and your electricity rates. However, it is estimated that a typical household can save up to $100 annually by unplugging appliances or using power strips to cut power when they’re not in use. This not only reduces your electricity bills but also helps reduce your carbon footprint.
