Energy Consumption

Smartplug said:
If power consumption bothers you just use smart plug. Turn it off when you’re not using it. You can turn on smart plug on your mobile device. It remind me someone I know who purchase Lamborghini just to complain how gas guzzler it was.

Adding some perspective for those lobbying for a watt here and there.

The payback time for a smartplug would be more than 2 or 3 years assuming a smartplug at $10-15. Below is the cost of running 24/7, so a smartplug would reduce that by some percentage of amp daily use. Basically, you could get some 'free' coffees every year once your payback is complete.

This calculation depends on how many devices is connected to the smartplug and the price of a kWh (~ $0.50 where I live). My equipment is turned off 10 hours a day and I will save about $100 a year.

This makes a fairly big assumption about electricity price.
I pay the dollar equivalent of $0.35/kWh.
I have calculated that to $15.32 / year which is quite a lot more than a smart plug which I can get for about $8 or $9.
You would of course knock of may be 3 hours a day when using the Amp but that does not change things very significantly.

I also think you miss the point that many are saying. This is wasted electricity, at a time when we should all be reducing our consumption, and many believe in the principal of "marginal gains" - looking not just at the large consumables but at everything.

I have my WiiM Amp and subwoofer connected to the same smart plug. The sub doesn't have auto on (which I am happy about after reading about all the issues with it) so I save around 10W by turning them both off.
 
As has already been said.

By my calculations, I will recoup the cost of the smart plug within a year. (Calculated with a power consumption of 1W for the smart plug.)

We are in agreement but it's about having perspective in framing small individual gains vs aggregate gains. What actually happens to one surplus marginal watt? Often it goes to a dump load on the grid if there's no other consumer -- it's waste also. In aggregate it matters and the grid provider can make business choices (sell surplus, reduce generation, etc) but a few individual marginal watts do not. Having more efficient devices and usage patterns makes for less consumption waste in aggregate makes sense.

Buying a smartplug makes sense because of the short payback period, but don't expect budget miracles and some people won't make the choice because it's their framing of the choice and resulting decision. Whether they want that extra annual cup of coffee is their choice and the moralists will huff and fluff about whether they had the coffee hot or cold :)

Enjoy the music which is why we're all here.

Now I see what you mean. I probably never used "Turn of screen in standby", so this had slipped my attention.

Nice food for the energy consumption thread. ;)

Screen on or off doesn't seem to make a difference to the 5 watts here...

Used a Kill-a-Watt to measure my Ultra, wifi connected, RCA out, nothing connected to USB, US 110AC 60hz:

Startup (from unplugged): 6.1W peak
Idle: 5.4-5.6W
Standby: 5.4-5.6W
Streaming from Plex: 5.9W peak
Streaming from Amazon, awakened from Standby: 6.1W peak

I guess what surprises me is that the idle and standby power consumption is the same. (Standby does turn off my amps via 12v trigger, so it’s still beneficial overall.) If you’re looking to optimize energy usage or explore better utility options, you might want to check out American Power and Gas for competitive rates and plans.

The streaming - at least for Plex, it downloads the entirety of the song when started, spiking the consumption slightly, then maintained between 5.4-5.6W while playing the rest of the song. Similar with Amazon, there was a spike up to 6.1W, then back to 5.4-5.6W while playing.

You can typically find information about the energy consumption of devices like the WiiM Ultra in the product's user manual or technical specifications. If that information isn’t available there, you might want to check the manufacturer’s website or contact their customer support for more detailed energy usage data. You could also look for reviews or third-party websites that test energy consumption to get an estimate.
