Most monitors today really shouldn't be using much more then 20W. My "TV" uses 8W. As measured with a power meter.
Wow! That is amazing.
My LG c1 TV pulls down 70watts when it is on. Although it is not hooked up to the computer, but runs its own OS like all the other smart TVs.
My Samsung monitor pulls about 40 watts continuously.
My Acer is around 30 wattish.
My computer box by itself pulls down 25-45 watts when it is browsing the internet, which is less then the the monitors I am looking at 30 + 40 = 70 watts.
My 2.1 computer speakers are always pulling down a few watts, not sure how many.
But the main sound system speakers are around 55 watts when idle. But this is likely because I am still using 80s tech from when I was a child.
Even my printer leeches 2-3 watts in idle.
I guess my watt consumption is in a completely different ballpark compared to yours. Along with that, what I view to be significant consumption.
( my electricity is at around 15 cents per kilowatt hour )
All of these electric costs seem irrelevant to me, as soon as I plug my car in they cease to be a significant component of my bill.
