Sky Plus energy usage question

Very simple really.
We are constantly reminded that leaving electrical items on standby uses a lot of energy and costs us lots of money and damages the environment etc etc...
on the telephone to a Sky engineer lst night who suggested that i leave sky on stand by when i go to bed instead of switching off at the socket.
Have the sky plus boxes been specifically designed to use minimal power on standby?
Will leaving it on standby use a lot of energy and cost a lot in electricity?

How much electricity does my Sky system use?
Experts estimate that set top boxes account for about 1.5% of home electricity use. It's a good idea to leave your system on standby when you're not using it, as it will use less electricity in this mode.
We're continuously developing new technologies to reduce the power required by our products. Electricity consumption of our set top boxes has been halved since we launched them. Sky is the only media company to have signed up to the voluntary EU Code on Energy Efficiency in Digital TV Service Systems and all our products are below the emissions levels it recommends.
Don't know if you would shorten their lifespan if you switched them off at the mains - that will cause a reboot whenever you switch on.

There are pros and cons of each.
1/ Electronics 'prefer' to be at a constant temperature. If they go cold, hot, cold every day you can get problems.
2/ If it is left switched on all the time, you will be vulnerable to voltage spikes (unless you use a surge protector) which can kill more modern power supply circuits.
3/ Sky boxes etc receive firmware upgrades at certain times.
If you were renting / leasing the box it would be best to switch it on /off because it wouldn't be your problem when it packed up. If there's a chance that you are going to have to pay Sky to come and fix / replace it, it would have to have saved a lot of electricity to be worth it! (I have a similar argument about modern overly complicated and often unreliable boilers)
I think the newer boxes might be slightly more efficient.
If the box is cold, it can't be using any power, if it's warm or even hot, then all this heat has come from your electricity. The label on the bottom of the Sky box shows the max power which I think is about 30W - hopefully it's using a lot less power than this most of the time - but Sky don't seem to be very good at specifics, they seem to put all their effort into marketing!
Another top tip: Leave plenty of air space around your Sky box - DO NOT COVER
ANY VENT HOLES and don't sit it directly onto carpet. If it stays cooler, it will prolong the life of the box.
This actually is optional. You can stop it (or start it) going into Autostandby.
We found it very annoying as the plug is quite far behind our equipment.
On your handset go into Services then Option 5
Turn it of at mains. Not a good idea as the harddrive within the unit it put in park mode that way. Also you do not know if recoding anything with pointless Anytime service on Sky+ or Sky HD box's.
No. Sky make up some phoney good PR about their standby function, but the fact is, unlike most other entertainment devices such as DVDs, TVs etc, every type of sky box has always been designed to remain continuously active in the background, and thus using a significant amount of electrical power even when pretending to be in 'standby'. It also continuously powers up the LNBs on your dish outside, which is a pure waste of energy as that doesn't even warm your house as a side effect.
Will leaving it on standby use a lot of energy and cost a lot in electricity?
Yes. It will still be using something like 20W in sky fake 'standby' mode, which for comparison is around 20 times that of a typical TV which has a genuine standby mode.
Our Sky+ box also tends to do drive maintenance overnight (not Anytime downloads...have disabled that, I mean disk defragmentation etc), generally at 4am. Although they may be using material amounts of power when on standby, for Sky+ it's definitely far less than in active mode, because (other than the burst of activity for maintenance) the hard drive's powered down.
My maths may be out, but if you unplug for say 10hrs a night, on dougz's figures that's 0.2KWH/day, or £6-7 / year. Is it really worth it?
