10 Common Household Items That Use More Electricity Than You Think

Published on August 3, 2025 • GreenEnergyTips.com

When it comes to saving electricity, most people focus on the big players like air conditioners and refrigerators. But did you know some of the most energy-hungry devices are also the ones you least expect? These sneaky electricity hogs might be quietly inflating your monthly bill.

1. Microwave Ovens

Microwaves are convenient, but they use more electricity than you might think — especially when used frequently or left plugged in. Even the clock display consumes power over time.

2. Fish Tank Equipment

Aquariums often require constant filtration, lighting, and heating — all of which can draw power 24/7. A larger tank can cost you more per month than you'd expect.

3. Gaming Consoles

Modern gaming consoles like the PlayStation or Xbox are powerful machines. Even in standby mode, they can draw a surprising amount of energy. Enable energy-saving settings to reduce usage.

4. Hair Dryers and Straighteners

Although they’re used briefly, hair dryers and straighteners consume a high amount of power while running. Frequent use adds up over time — especially in larger households.

5. Toaster Ovens

Smaller than conventional ovens, toaster ovens are often assumed to be more efficient. But depending on use, they can draw a lot of electricity — especially older models.

6. Space Heaters

Space heaters are notorious for their electricity usage. Running one for a few hours each day can easily double a room’s monthly energy cost. Consider better insulation or layered clothing.

7. Clothes Dryers

Dryers are among the top residential energy consumers. Opt for air-drying when possible or dry multiple loads consecutively to take advantage of retained heat.

8. Desktop Computers Left On

Leaving your PC on overnight or while idle for hours contributes to phantom load. Set it to sleep automatically or shut it down when not in use.

9. Always-On Chargers

Phone, laptop, and device chargers draw a small amount of electricity even when not charging. Unplug them when not in use or connect to a smart strip.

10. Electric Hot Plates and Kettles

These are energy-intensive devices, especially when used frequently. Heating water with electricity is one of the most energy-demanding tasks in the home.

Final Thoughts

While each device may not individually cause a spike in your bill, the combined effect of several in use can be substantial. The first step to controlling your energy bill is awareness. By identifying which devices consume the most electricity — even the small ones — you can take smarter action toward reducing your consumption.
