Right now, while you read this, your TV is burning electricity. So is your gaming console. Your phone charger. Your microwave. That old printer you never use. They're all plugged in, all drawing power, all costing you money — even though nobody is using them.
This invisible drain has a name: phantom power. And it accounts for 5-10% of your total home energy bill. With average electricity rates hitting 17.45 cents per kWh and climbing, that "nothing" adds up to hundreds of dollars a year.
The fix? A smart plug that costs less than a large pizza. For $8-15 per plug, you get real-time energy monitoring, automated schedules, and the ability to kill phantom power from your phone — or with your voice. The best smart plugs for energy saving in 2026 pay for themselves within weeks, then keep saving you money every single month.
Here's exactly which ones to buy, how to set them up, and which devices to prioritize first.
Key Takeaways
- Smart plugs eliminate phantom power drain, saving you 8-15% on your electric bill
- Devices on standby ("off" but plugged in) waste 5-10% of your total home energy
- The TP-Link Kasa EP25 offers the best energy monitoring at under $15 per plug
- Schedule high-draw appliances to run outside peak hours (avoid 4pm-9pm) for extra savings
- Start with your entertainment center, space heater, and gaming console for the biggest impact
- Pair smart plugs with a smart thermostat for up to 25% combined energy savings
What Phantom Power Actually Costs You
Walk through your home right now and count every device that's plugged in but not actively being used. Your TV. The cable box. The game console in sleep mode. The soundbar. The laptop charger with no laptop attached. The smart speaker. The coffee maker with a clock display.
Every one of those devices draws power — all day, every day. This phantom load (also called vampire power or standby drain) typically accounts for 5-10% of a household's total electricity use. For the average American home, that's roughly $100-200 per year spent powering absolutely nothing.
And here's what makes it sting: electricity rates aren't going down. At 17.45 cents per kWh (the current national average), every watt your idle devices pull costs real money. A gaming console in rest mode draws 10-15 watts continuously. Your cable box? Up to 30 watts — whether you're watching it or not.
The traditional fix — unplugging everything manually — works but nobody actually does it. Smart plugs give you the same result with zero daily effort.
How Smart Plugs Save You Energy
A smart plug sits between your device and the wall outlet. When the plug is off, zero electricity reaches your device. No phantom drain. No wasted watts. No money burned.
But cutting power is just the starting point. Here's how smart plugs actually reduce your bill:
Schedule-Based Automation
Set your entertainment center to power down at midnight and turn on at 6pm. Your home office gear shuts off at 5pm and wakes up at 8am. No standby drain during the 12-16 hours you're not using those devices. This alone eliminates most phantom power waste.
Real-Time Energy Monitoring
Plugs with built-in energy monitoring show you exactly how many watts each device draws — in real time. You'll discover which devices are the worst energy vampires. That old mini-fridge in the garage? It might be costing you $15/month. You'd never know without measuring it.
Off-Peak Scheduling
Many utility companies charge more during peak hours (typically 4pm-9pm). Smart plugs let you schedule high-draw devices — like space heaters, portable ACs, and dehumidifiers — to run during cheaper off-peak windows. If your utility uses time-of-use pricing, this shift alone can cut 10-20% off your bill.
Voice and Remote Control
Left the house and forgot to turn off a lamp or a fan? Kill it from your phone. Leaving for vacation? Power down everything except the fridge with a single voice command. No more coming home to discover you've been heating an empty room for a week.

Which Devices to Plug In First
Not every outlet needs a smart plug. Focus on the devices that draw the most phantom power. Here's your priority list, ranked by typical standby waste:
- Entertainment Center (TV + soundbar + streaming stick + game console) Draws 30-80W combined on standby. Biggest single source of phantom power in most homes.
- Gaming Console (PS5, Xbox Series X) Rest mode pulls 10-15W continuously. That's $15-25/year doing absolutely nothing.
- Desktop Computer + Monitor Setup Sleep mode still draws 5-15W. Peripherals (speakers, external drives) add more.
- Space Heater or Window AC Schedule these to avoid peak-rate hours (4pm-9pm) and save on time-of-use pricing.
- Phone and Laptop Chargers Each draws 0.5-2W when plugged in with nothing attached. Small per charger, but you probably have 4-6 of them.
- Old Mini-Fridge or Garage Fridge Older fridges run inefficiently and cycle on/off all day. Use a monitoring plug to measure the actual cost — you might be shocked.
- Coffee Maker with Clock Display That always-on clock draws 2-5W. It's small, but a smart plug automates your morning brew AND kills standby.
Pro tip: Plug your Kill A Watt meter into the outlet first to measure exactly how much each device draws on standby. Then replace it with a smart plug for the worst offenders. If you want ongoing tracking, go straight for a plug with built-in energy monitoring.
Setting Up Energy-Saving Routines
A smart plug without a good routine is just a fancy on/off switch. Here are three schedules that save real money:
Morning Routine (6:00 AM)
- Turn on coffee maker
- Power up home office (monitor, desk lamp, printer)
- Turn off bedroom chargers
Night Routine (11:00 PM)
- Kill entertainment center (TV, soundbar, gaming console)
- Shut down home office completely
- Turn on bedroom chargers (charge overnight during off-peak)
- Turn off kitchen appliances (coffee maker, toaster oven)
Away Routine (triggered by phone location or manual)
- Kill all non-essential plugs with one command
- Keep fridge, security cameras, and router powered
- Activate random lighting schedule for security
Most smart plug apps (Kasa, Meross, Govee) let you build these routines directly. If you use Alexa, create grouped routines that control multiple plugs with a single voice command: "Alexa, good night" kills your entertainment center, office, and kitchen in one shot.
Smart Plugs + Smart Thermostats: The Power Combo
Smart plugs handle your devices. A smart thermostat handles your HVAC — which accounts for roughly 40-50% of your total energy bill. Combine both, and you're addressing the full picture.
Here's why they work better together:
- Space heater scheduling: Use a smart plug to run your space heater only during the hours you need it, while your thermostat lowers the whole-home temperature. Heat the room you're in, not the whole house.
- Window AC control: Smart plugs let you schedule window units to pre-cool your bedroom before you arrive, then shut off at night. Meanwhile, your thermostat manages the central system efficiently.
- Fan automation: Run ceiling or standing fans on a schedule to circulate air, allowing your thermostat to maintain comfort at a higher temperature setting (each degree up saves ~3% on cooling costs).
Want help choosing? Our guide to the best smart thermostats (Ecobee vs Nest) breaks down which one matches your setup. And if you want to see where all your energy goes before buying anything, start with a whole-home energy monitor.

How Much Will You Actually Save?
Let's run real numbers. Say you have a typical setup: entertainment center, gaming console, home office, and a few chargers. Those devices draw roughly 50-100 watts combined on standby, 24/7.
At 17.45 cents per kWh, that's approximately $75-150 per year in phantom power alone. Smart plugs with schedules eliminate nearly all of that. Add in off-peak scheduling for your space heater and window AC, and you're looking at 8-15% total savings on your electric bill.
A 4-pack of Meross plugs costs about $28-32. A 2-pack of Kasa EP25s runs about $24-28. Either way, the plugs pay for themselves within 1-3 months. Everything after that is pure savings.
That's what makes smart plugs one of the highest-ROI purchases you can make for your home. Not the flashiest smart home gadget — but the one that literally pays you back.
