Your TV, computer, gaming console, and phone chargers may seem like small energy users. Individually they are—but collectively, and especially when left on standby, electronics can add $5–$20 or more to your monthly bill. Here's where the hidden costs come from and how to reduce them.
TV Energy Consumption
Modern LED and OLED TVs are far more efficient than older plasma or CRT models. A 55-inch LED TV typically uses 60–90 watts when on; a 65-inch might use 80–120 watts. The bigger the screen and the brighter the settings, the more power it draws. Smart TVs also use power in standby mode to maintain connectivity—often 5–15 watts 24/7.
Computers and Monitors
A laptop uses 15–60 watts depending on load; a desktop PC can use 65–250 watts. Gaming rigs with high-end graphics cards may draw 300–500 watts under load. Monitors add 15–75 watts. If you work from home with multiple screens and a desktop running 8+ hours daily, that can easily add $15–$30 per month.
Gaming Consoles and Set-Top Boxes
Gaming consoles use 70–200 watts when gaming, but many draw 10–15 watts in standby for quick startup and updates. Cable boxes and streaming devices often run 24/7, using 15–30 watts each. Multiple set-top boxes and a console in standby can add $5–$15 monthly.
Chargers and Small Devices
Phone and laptop chargers draw minimal power when plugged in without a device—usually under 1 watt. But with dozens of chargers, smart speakers, and smart home devices, the total can add up. A single smart speaker might use 3–5 watts constantly.
How to Cut Electronics Energy Use
- Enable power-saving modes: TVs and computers have sleep and eco settings.
- Unplug or use smart strips: Cut power to entertainment centers when not in use.
- Turn off gaming consoles fully: Avoid instant-on modes that keep them in standby.
- Consolidate devices: One streaming device instead of multiple set-top boxes.
- Lower screen brightness: Reduces power draw on TVs and monitors.
"The average household has 40+ electronic devices. Even at 1–2 watts each in standby, that's 40–80 watts running 24/7—roughly $35–$70 per year at $0.12/kWh."
Estimate Your Electronics Bill
Use ElectriBill's calculator to add up your electronics. Enter wattage for TV, computer, and other devices, estimate daily hours, and see the impact. Don't forget to account for standby time—many devices draw power even when "off."
