The average US household wastes $100–$200 per year on phantom load — electricity drawn by devices that are “off” but still plugged in. Your TV, game console, cable box, computer monitor, and phone chargers all do this. Smart power strips cut that waste automatically, with no behavior change required from you.
LED bulbs are a separate but equally fast win. If you still have any incandescent or CFL bulbs, swapping them saves 75–80% on lighting electricity and the bulbs last 15–25 years. At California rates, each bulb swap pays back in a few months.
A cable box uses nearly as much power off as on (~15W, ~$20/year). A gaming console in standby: ~10W. A TV: 1–5W. A home theater receiver: 5–15W. None of these feel significant alone — together they add up fast.
| Device | Standby watts | Annual cost (CA rates) |
|---|---|---|
| Cable / satellite box | 10–18W | $15–$26/yr |
| Gaming console (PS5/Xbox) | 0.5–13W | $1–$19/yr |
| TV (modern LED) | 0.5–3W | $1–$4/yr |
| Home theater receiver | 5–20W | $7–$29/yr |
| Desktop computer + monitor | 2–10W | $3–$15/yr |
| Microwave (display clock) | 2–4W | $3–$6/yr |
| Phone / laptop chargers (idle) | 0.1–0.5W each | Small but accumulates |
A Kill A Watt meter (~$25) plugs between your device and the wall and shows real-time wattage. Plug it into your TV setup or home office and see exactly what each device draws in standby. Takes 30 seconds per outlet. Great for prioritizing where to focus.
A smart power strip has one “control” outlet and several “switched” outlets. When the device in the control outlet (e.g., your TV) turns off, the strip automatically cuts power to everything else (receiver, console, cable box). Zero standby draw. Nothing to remember.
For your home office: plug your monitor into the control outlet and your desktop, speakers, and lamp into the switched outlets. When the monitor sleeps, everything else shuts off.
Check every fixture. Incandescents are warm-colored and get hot to the touch. CFLs are spiral-shaped and take a few seconds to brighten. Both should go. Modern LEDs are available in every color temperature from warm white (2700K, like incandescent) to daylight (5000K). Most people prefer 2700K–3000K for living spaces, 4000K for kitchens and bathrooms.
California utilities frequently run programs where you can get free LED bulbs at participating retailers (Home Depot, Lowe’s, Walmart) or by mail. These are fully subsidized — you just pick them up. Check the link for your utility before spending anything.
For appliances that need to stay on (router, modem) or devices in awkward spots, a smart plug lets you set a schedule or control it by voice or app. Program your home office smart plug to cut power at midnight and restore at 7am. Costs ~$10–$15 each and works with Amazon Alexa, Google Home, and Apple HomeKit.
