Standby power might seems insignificant on its own. But it does account for 5-10% of your energy bill. For a family that would equate to the costs of 10 Raspberry Pis....And mutilpying it by all the biilions of devices it adds up to a massive amount. Reported in 2008 to be around $4 Billion in the USA per year.
I have all my equipment on a power switch with a remote control - that switches off the power to all at once.
Let's keep things in perspective here, your other devices you say your able to control so you don't need consider them.
All that leaves is your Pi itself, maybe you have loads of them, but I'm assuming not. A single Pi running 24/365 is still a negligible cost when looking at your overall energy bill.

Well - the issue here is that previously as you could set in the CEC control settings, switching off the TV switched off the pi too and so this RC has a bug that stops this happening.
My other concern is that the Pi runs very hot and so I like to give it a rest. Also switching it off at the power without being able to shut it down can corrupt the system.
I have installed (auto installed actually) 0.4.0 , but now when I start rasplex and it show the start menu all menu items change into "search" (and they actually also get this function). I can go to the preferences menu (by pressing the left arrow on my remote) and there all seems fine. I also wanted to setup a fixed IP address fro the plex server but it seems not possible to press the "done" button after I entered the IP address.
Also the "search" menu problem now an then switches back to normal and then again to all "seach" menu's.
Also for some reason in some cases I also got a reboot of the rasplex. Very strange behavior. With version 0.3.1 I never got these problems.
I then flashed the SD again with 0.3.1 and all seems to work like before again, this way I hope to rule out any hardware problems.
Anyway know what is going on here anyone know why I get this kind of behavior with 0.4.0 ?
This is off topic - but as Adam_311 brought up thhis issues and does not seem to be signed up to the Kyoto Prococol
Assuming the Raspberry Pi has a 90% efficiency, the idle power usage with just network and HDMI monitor connected (no USB etc plugged in) is 0.9 * 12.5 * 0.19 = 2.14 watts
2.14 watts at 24 hours x 30 days = 1.541 kW/h (This is 1/2% of my total monthly energy bill)
2.14 watts x 24 hours x 365 days = 18.75 kW/h per year
Now if every person in the USA got a Raspberry Pi and left it on 24/365
18.75 kW/h x 313.9 million = 5,885,625,000 kW/h per year
In energy cost terms = US$1,000,556,250 per year
Wow over a billion dollars - - we had better get this Rasplex CEC settings power off bug fixed asap or someone is going to get a very big bill.
Oh my god we will kill the planet and bring about the downfall of the global economy with this bug. Who would have thought a media device could do such a thing, but the maths clearly shows it to be a certainty!

Wow Dude, your really blowing this way out of perspective!
For a start, there's little chance of everyone in America rushing out to buy one. Even if they did, some would and some wouldn't leave it running, despite what the Kyoto Protocol says.
As for your sums there, I'm no electrical expert nor mathematician. But what I can do is go to my electricity monitor and get a current reading, then pull the power on my Pi and re-read the output. It's fractions of a pence difference.
Now if that, albeit over a month, equates to half of your electricity bill then I surely do envy you
Raspery pi uses fu** all electric. I leave mine on 24/7. Only thing the shutdown button is needed for is when u need to put, either the USB or SD in the PC. ( once in a blue moon)
I think Adam_231 would change his mind if the bill was sent to him.
A Raspberry Pi left on all the time would be 1/2 percentage of my monthly usuage (Adam_321 missed the % symbol)
Yeah we all know it is unlikely that everyone in the USA is going to rush out to buy a Raspberry Pi that they will leave on - but everyone in the world is leaving on devices that they think are inconsequential or do not realise that the devices are taking power. So it is important to fix a bug that lets one power off a device instead of encouraging people to leave them on.
But what is more the AC power adapter that one uses to power the Raspberry Pi will continue to use power even if the Raspberry Pi is shutdown. and even if it is not plugged into the RaspberryPi but left plugged into a switched on socket. The AC power adapter can be using between 0.8 W to 2 W even when unpluugged from the device but left inthe socket with the switch on. That is unless the AC Power Adapter has special EcoSmart Technology that senses when it is in a standby state and then reduces power draw.
So you see it is important to switch off at the wall. And to switch off at the wall one needs to first power down the Raspberry Pi so as to not chance corrupting the system.

Before saying CEC PowerOff doesnt work, did you even configure it ? :)
The Power Saving features in System Preferences have no effect. They do not shutdown the device.
Perhaps they are there just for decorative reaons as users prefer to leave on the Raspberry Pi all the time. :wacko:
I'd have same question as the one i asked in the issue you filed.
If you want us to have a look into your issues, we'd like to have some more detailed description than : X doesnt work.
There are many users reporting issues and we'd like to save the guesswork and concentrate on scenarios where you can reproduce the issue, if any, to be able to fix it :)

Yes - I checked the configuration when I found it was not working as before - but the auto update had kept my previous configuration. I have had to set the WHEN TV IS SWITCHED OFF settings to IGNORE. Otherwise when I turn off my Samsung TV and AV using the remote the Raspberry Pi simply reboots and turns them on again. This happens for both the Suspend and Shutdown options.
The CEC configuration does however, on power on of Raspberry Pi, switch on the TV and AV and change to the TV to XMBC (Raspberry Pi) as active source as I had set before.
The Shutdown & Quit on the main screen also do not work and only reboot the Raspberry Pi
Similarly I set the Power Savings settings to Shutdown after 5 minutes. but this has no effect...
The only way to Shutdown the device is pull the power on it.

I would be happy to give you more information as to why the settings are not functioning but unfortunately if a setting does not function as it should, that is all one can say about it.
So one sets the Power Saving setting to Shutdown the Raspberry Pi after 5 minutes and waits and after a 1/2 hour it obvious that it does not do what its says on the box as the device is still not shut down.
Do you think there would be any log files of when nothing happens?

Annual cost of some other devices standby energy consumption (based on a U.S.A electrical costs of $0.17 per kWh and U.K. electricity costs of £0.134 per kWh:
Vampire energy accounts for 1 percent of the world's carbon dioxide emissions.
In the USA it takes over a dozen power plants to supply the energy used by devices on standby.
In the UK it takes 3 power plants to supply the energy used by devices on standby.
Great information there , thank you , where do you find this stuff out?
I have similar too yourself , a power block with a remote switch that switches 6 devices off and leaves two on ( router and cordless phone )
If most people who bought a PI left that on and switched everything else off , all would be a bit better perhaps :-)
It just makes sense to switch things off , it saves you money , simple as that .

I dont recall such a bug filed and still openned, so please file one and try to explain the exact steps to reproduce it.
Actually, I've spent a little time working to fix this today. Seems disabling the option in the preferences and then re-enabling it has fixed the video functionality.
I can now play videos via AirPlay using YouTube, Vimeo and Photos.app.
Some of the videos seem to just crash the player though, but that could be a network issue.

Maybe simple switch and/or timer could solve you problem also ;-). Your TV alone uses as much or more then a Rbi just in standby. Not to mention your Microwave, oven, clocks, etc etc ... All running 24/7. ;-)
