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.

Thays 50x the base load of my house, and would cost thousands a year to run idle. With current costs in the UK, close to $10,000

There were devices that consumed 80 watts in standby. I have a cabinet full of equipment including my cable modem, a computer (server, no monitor) with 8 mechanical hard drives. The idle current is 76 watts or so. How could something be so high?

'standby' for many devices used to mean 'leave all the electronics powered up, but turn the screen/sound off'.

I had a DirecTV satellite receiver with DVR. They rolled out an update and made a big deal their new "Energy Star ECO power savings mode."

I wondered how much power it could really save because it was a DVR with a spinning hard drive that would always record the last 30 minutes of the current channel even if you didn't set it to record anything explicitly.

So I measured it while on and also in "power savings mode" where the video output was off.

14.5W when on and 14.0W when in "power savings mode"

What a joke.

A modern phone with a 5 Ah ( ~ 18.5 Wh) battery can run for many hours streaming to a builtin screen, meaning it uses far less (anything over 45 minutes is more energy efficient) than a chromecast despite doing more. Same scenario with a laptop with a 60 Wh battery, which can also run a long time in idle, and even while streaming, and is able to resume from sleep in a second. Running more than 2.5 hours on battery means it's more energy efficient than a Chromecast.

And this has built in Chromecast. I love my Shield.

I love that my home screen is now jammed full of bullshit and it cannot be used without a Google account and if you use your personal Google account Nvidia needs a ton of permissions. Other than that I actually do the love the little device but I feel more and more jerked around when I shell out only to have junk foisted on me later.

All the ads on the home screen suck now. When I first got my shield I made another account just for it because I didn't want it connected with the rest of my google stuff.

Not tellies but an interesting look by Dave Jones[of EEVBLOG fame] into how/why simple devices can use up so much power when idle. A lot of it is down to lazy design of the AC>DC circuits https://www.youtube.com/watch?v=_kI8ySvNPdQ

It’s not lazy, it’s cost optimized. Like so many times, market forces just force any externalities outside the price signal.

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.)

Is that the case with all OLED displays? like a phone screen, etc.?

Is heating/hot water in that 1.5kW?

Heating and hot water is gas, cooling is electric.

Amazing. That's about a factor 4 more than average total consumption around here. Which I am beating by almost a factor 2.
