I turn most of my HiFi off, but I am guilty of leaving my TV on (and my computer - which is probably much worse but is obviously not a problem because it wasn't mentioned in the article)
What I find curious is the graph that shows the expected current consumption of TVs in the future - it seems to bare no resemblence to past trends, and also says nothing of the fact that LCD TVs use less than half the current of a CRT (well, when working).
I have never consumed a TV though I am sure they're tasty (if a little crunchy) you want to get it before the capacitors blow up, that leaves a nasty aftertaste (in the whole house...)
At least you'd think that in winter the extra heat from stereos goes into heating the house, and if it's thermostatically controlled that's ok. In summer there's no excuse.
Am I right in thinking that high end hifi are designed to be left on all the time?
I still can't work out where the TV's get all the currents that they're consuming? Tescos?

They're not specifically designed to be left on, more that they sound better when they are. Thermal stability and all that. Jagwap can tell you all the pixy dust crap about why.
*50,000,000 (conservative count of DVD+TVs in the UK, but we have to allow for them to be on and in use some of the time)
that's 250MW, roughly the output of a nuclear power station!
and that's ignoring the computers... which have 250W+ power supplies... (I doubt they use 250W all the time, but why else have 300W or 400W power supplies if you're not going to use them?)

Another detailed and in depth report - NOT!

TV - <2W
PVR - doesn't say but max power is 24W
DVD - 1W
So not too bad.
But then there is my computer and server which I leave on - Oops! Although my server is a low power mini-itx job.
