Phantom Load — The Electricity You're Paying for Without Knowing
Phantom load (also called standby power or "vampire power") is the electricity devices consume while switched off but still plugged in. Individually each device draws only a small amount, but combined — TV, cable box, router, computer, game console, microwave — a typical home draws 20–50 watts continuously. This adds up to $100–200 per year in wasted electricity.
The Biggest Standby Power Offenders
Cable and satellite boxes are often the worst, drawing 5–17 watts 24/7 even when "off." Routers draw 5–8 watts continuously, which is unavoidable if you need internet access. Desktop computers and monitors draw 5–10 watts in sleep mode. Game consoles in standby mode can draw 0.5–10 watts depending on network update settings. Turning off "instant on" features in TV and console settings significantly reduces standby draw.
How to Reduce Phantom Load
Smart power strips cut power to devices automatically when a control device (e.g., TV) is turned off. Unplugging chargers when not in use eliminates their small but constant draw. Enable "eco mode" or "power saving mode" in device settings to reduce standby consumption. For home entertainment systems, grouping TV, cable box, and speakers on one switched power strip makes it easy to cut all standby at once.
Energy Star Standby Standards
Energy Star certified products must draw 0.5 watts or less in standby mode. When buying new appliances, check the EnergyGuide label for standby power consumption. Replacing old, power-hungry standby devices with certified products can cut standby consumption by 50–90% per device.
Frequently Asked Questions
Electricity consumed by devices when switched off but still plugged in — keeping remote controls, clocks, and charge-ready circuits active.
The US DOE estimates standby power costs the average household $100–200 per year — about 5–10% of the annual electricity bill.
