I have every single device plugged in to a switchable extension cord for this reason. No need to trust a manufacturer, not even a 1-5W consumption (times the number of devices).

I also put everything except my fridge, freezer, and router on switchable extension cords. Why waste even a single watt-hour on things I don't use?

It feels like over optimization. The base load of my house is around 1kW which is still completely irrelevant in the scheme of how much owning the property costs. The literal cost you’re adding as well as the mental cost of having to switch things on and off all the time shouldn’t be ignored. There’s a timer on the outlets for the soldering gear though, that adds a bit of peace of mind.

(: guestimates are good enough, everything pales in comparison to the freezer, turn that off and the power bill goes down

Are freezers really that bad? Does it depend if they're chest or standup? I don't remember my bill going up when I added a freezer, I didn't really measure though.

A chest is much better. The reason is intuitive: if you open it the cold air remains inside except for a little turbulence at the top and, of course, the new air that pours in to replace whatever you’ve just removed.

Whereas, when you open an upright one, cold air immediately starts pouring out the bottom of the opening, with warmer air coming in at the top to replace it.

Modern freezers really aren't that bad. Chest freezers being better than standing, because less of the cold air escapes when it is opened.

The US requires all consumer appliances to have an Energy Guide sticker (the yellow and black thing) which estimates an annual KWh use and cost at average electric prices. My cheapo 4cuft chest freezer uses about 200 KWh annually, or about $25. Not nothing, but $2 a month isn't going to register compared to most things.

If you're wondering how much energy is consumed by your electronics, a base model kill-a-watt for about $30 will show you watts and cumulative watt-hours. It's a fantastic tool that pays for itself besides giving an eye-opening, interesting experience. You'd be surprised at the things in your house consuming electricity 24/7. Almost everything in my house is either on power strip surge protectors or just unplugged.

I’d actually recommend a wifi smart plug with energy monitoring Easier to read the display on your phone ;)

Yes, get a cheap IoT plug supported by Tasmota and enjoy monitoring, toggling and time-based schedules without "phone home" features :-)

Yea, but it keeps my food cool and thus edible for several days longer than it otherwise would. Power usage of a device isn't the problem, power used not doing useful work for me is.

Why? does turning off an oled TV cause problems?

Yes. OLEDs run a short matrix refresh cycle every few working hours and a long one every hundred or so after you put them to standby; you probably won’t break anything, but the TV quality will degrade quicker. (Not sure about the not breaking part, though ;) I leave mine powered on.)

It needs power or it degrades faster? Sounds like a great reason for me to never buy an OLED tv.

Television isn’t my primary choice for media, but when I do I just unplug it when I’m done. 0W standby. Same for basically everything other than the refrigerator and wifi.

You don’t want to do this with an OLED TV though.

I'm seeing videos and articles saying that leaving it on is to let the OLED pixels refresh every 4 hours. How important is it, really?

The pixel refresh thing doesn't seem to make any scientific sense to me as a layperson.

Your energy use is going to be much more impacted by how full you keep your freezer. For the same reason.. the more product you have in there, the less air you have in there.

Your chest freezer will typically use about the same about of yearly kWh as a standing freezer would, but the chest freezer will typically have about 30% more capacity.

So.. it's "better," but if you're not going to keep it full, you may not actually be saving any total energy.
