If you’re asking whether unplugging your TV, cable box, and kitchen appliances every night for four weeks can noticeably lower your electric bill, yes—but the savings depend heavily on the appliances.
What probably happened
- TV: Usually a relatively small saving. Modern TVs consume very little power when turned off, although standby consumption varies.
- Cable/satellite box: This can be more significant because some set-top boxes use power continuously, even when you’re not watching TV.
- Kitchen appliances: Unplugging things such as a microwave, coffee maker, toaster oven, or air fryer can eliminate their standby consumption. However, appliances that are actually heating or cooling use much more electricity while operating than they do in standby.
- Refrigerator/freezer: Don’t unplug these overnight. They need to remain powered to keep food at a safe temperature.
A simple example
Suppose your unplugged devices collectively consumed an average of 10 watts while sitting idle.
10 W × 12 hours/night × 28 nights ≈ 3.36 kWh saved.
That’s not necessarily a huge reduction in a bill. If several devices were drawing considerably more standby power, the savings could be larger.
So if someone claims that unplugging a few appliances cut their electric bill dramatically, I’d be skeptical without seeing the actual before-and-after bills and the devices’ power consumption.
If you give me your old bill amount, new bill amount, and the appliances you unplugged, I can calculate how much you actually saved.
