Does Unplugging Appliances Save Electricity in Sri Lanka?
With rising electricity costs and frequent power cuts in Sri Lanka, many households are looking for ways to reduce their power consumption. One common piece of advice is to unplug appliances when not in use. But does this actually help save electricity, or is it just a myth?
The answer: Yes, unplugging certain appliances can save electricity, but the savings depend on the type of device and how often you use it. Some electronics continue to consume power even when switched off—a problem known as "phantom energy" or "vampire power."

Let’s explore!
How Much Electricity Do Appliances Waste When Plugged In?
Many modern appliances and gadgets still draw power even when turned off. This is called standby power consumption, and it can silently increase your electricity bill.
Common Appliances That Drain Power in Sri Lankan Homes
Televisions & Set-Top Boxes – LED TVs, Dialog TV, and PeoTV boxes often stay in standby mode.
Phone & Laptop Chargers – Many people leave chargers plugged in 24/7, wasting energy.
Microwaves & Rice Cookers – Appliances with digital clocks or standby lights consume power.
Fans & AC Remote Controls – Some fans draw small amounts of power waiting for remote signals.
Modems & Routers – SLT or other Wi-Fi routers often run continuously.
How Much Does Standby Power Cost in Sri Lanka?
According to the Ceylon Electricity Board (CEB), standby power can contribute to 5-15% of a household’s electricity bill. For example:
If your monthly bill is LKR 5,000, phantom energy could cost you LKR 250–750 per month.
Unplugging just a few devices could save LKR 300–500 monthly.
Does Unplugging Appliances Really Help in Sri Lanka?
The impact varies depending on the appliance. Some devices barely use standby power, while others are major energy wasters.
Appliances Worth Unplugging
✔ Entertainment Devices (TVs, set-top boxes, speakers)
✔ Chargers (phone, laptop, tablet)
✔ Kitchen Appliances (microwaves, blenders, rice cookers)
✔ Computer Equipment (monitors, printers)
Appliances You Don’t Need to Unplug
✖ Refrigerators (Unplugging will spoil food)
✖ Clocks & Emergency Lights (Very low energy use)
✖ Wi-Fi Routers (Needed for internet access)
Easy Ways to Save Electricity Without Unplugging Everything
If unplugging devices seems inconvenient, try these alternatives:
1. Use Multi-Plugs with Switches
Turn off multiple devices at once with a single switch—great for TVs, chargers, and gaming consoles.
2. Enable Power-Saving Modes
Many modern TVs, ACs, and fans have energy-saving settings—activate them!
3. Unplug Chargers After Use
Leaving phone chargers plugged in wastes electricity even when not charging.
4. Upgrade to Energy-Efficient Appliances
Look for 5-star energy-rated devices to reduce standby power consumption.
Should Sri Lankans Unplug Appliances?
Yes—but focus on high-power devices. Unplugging TVs, chargers, and kitchen gadgets can lead to noticeable savings, especially with Sri Lanka’s high electricity rates. For other appliances, use smart switches or power strips to minimize waste.
By making small changes, Sri Lankan households could save LKR 3,000–6,000 per year—just by being mindful of standby power!
