I just measured it with our handy $20 KILL-A-WATT meter and the FIOS set-top-box… when off (on “standby”)… uses 16W! That’s 24/7. Even if you are not watching TV and carefully turned the thing off.
Here’s the math for a year:
16 * 24 * 365 / 1000 = 140 KWh
If you pay $0.15/KWh then that’s $21 per year you pay** for that. In the Northeast in some city/towns, you probably pay closer to 0.20 or maybe 0.23 if you pay extra for GREEN electricity (Or use NEW ENGLAND WIND FUND if you use a Municipal).
Anyway, the important point is that this is approximately the equivalent to 1/2 of the output of a typical 230W solar-electric PV panel on a reasonably South-facing roof in MA for a year according to PVWATTS.
IOW, turn junk off with a powerstrip! It’s cheaper than buying solar panels!
And Verizon, you can do better! Shame shame! Some things in our house use less than 1W when “turned off”! Not 16W!
**In the winter, this extra 16W is helping to heat your house, but there are much cheaper ways to heat your house than using phantom loads!
