Average annual savings by eliminating standby / vampire power drain
What Is Vampire Power?
Vampire power — also called phantom load or standby power — is electricity consumed by electronic devices when they appear to be off but are still plugged in. Every device with a standby mode, clock display, remote control receiver, or "instant-on" feature draws power continuously.
According to the Lawrence Berkeley National Laboratory, vampire power costs the average American household $150–$200 per year — roughly 10% of total electricity consumption. Nationally, this waste totals about $19 billion per year.
The fix is surprisingly simple and costs about $25.
The 10 Worst Energy Vampires in Your Home
These devices draw the most standby power, ranked by typical annual cost:
- Cable/satellite box: ~$30–$50/yr (often runs 24/7 even when "off")
- Gaming console (PS5/Xbox): ~$25–$40/yr (instant-on mode)
- Desktop PC + monitor: ~$20–$35/yr (sleep mode still draws power)
- Large TV (55"+): ~$15–$25/yr (smart TV apps update in background)
- Microwave: ~$10–$20/yr (clock draws constant power)
- Stereo / audio receiver: ~$10–$15/yr
- Phone/tablet chargers: ~$5–$10/yr each (unplugging all saves $15–$30)
- Inkjet printer: ~$8–$12/yr
- Coffee maker: ~$6–$10/yr (display clock)
- Smart home devices (Alexa, Google Home): ~$5–$8/yr each
The $25 Fix: Smart Power Strip
The easiest solution for entertainment centers and home offices is a smart power strip. These strips detect when a "master" device (like your TV or PC) turns off and automatically cut power to all connected "slave" devices (cable box, gaming console, speakers, etc.).

Know Your Hogs: Energy Monitor
Before you buy anything, it's worth knowing exactly which devices are costing you the most. An energy monitor plug gives you real-time wattage and monthly cost estimates for any appliance.

🛒 View on AmazonPlug any device into the energy monitor for 48 hours. Multiply the daily kWh by 365, then by your local electricity rate. Most people are shocked to discover their old desktop PC costs $60/yr in standby power alone.
Free Vampire Power Fixes
You don't have to buy anything to start saving right now:
- Unplug phone chargers when your phone is fully charged or not in use. Each charger costs $5–$10/yr plugged in idle.
- Enable PC sleep mode — go to Power Settings and set sleep to activate after 10 minutes idle. Saves $15–$25/yr vs. screen saver mode.
- Unplug the TV at night — Smart TVs use 5–10W standby, running app updates and firmware downloads 24/7.
- Microwave: unplug when not in use — the clock on a microwave can cost $10–$15/yr. Use your phone for the time instead.
- Use a basic power strip with a switch — flip one switch to cut all devices at once. Free (use one you already own).
