It depends on your monitor type of course, but a typical computer display in use consumes about as much energy as an incandescent room bulb, i.e. 100 watts or less.

In sleep mode, it's only 0-15W. If you're in front of it and don't even notice it's on, then it's asleep and you're using little to no energy.


(My iMac is set to sleep after 20 minutes, and the hard drives switch off after another 10 minutes of inactivity.)

Same here... standby / sleep mode after a period of inactivity

I leave all my computers and peripherals on. Most are Energy Star. I'm not worried about power consumption nor costs (at least not right now; I may if these fuckers get the NEMA 3.0 that they are proposing). Nor am I worried about product life.

All of these devices are negligible power levels I believe relative to dishwasher, washer, dryer, AC/Furnace, oven and other large, regularly used appliances.

The only thing I turn off for the evening is the TV/receiver. For no real reason other than habit.

I haven't encountered any real reason to turn anything off; many things have a sleep/quick resume state.

Yes they go to sleep after a set period of time.

The only time my desktop computer and monitor are turned off is when I'm going out of town for a while. The monitor does not "sleep". I do reboot the PC every so often.

Just looked up the specs on mine.

Max: 29 watts
Sleep Mode 0.3W

Definitely not worth turning off.

I leave mine on 24/7, except when I'm leaving town for more than 4 or 5 days.

I run through a UPS, with monitoring. When in sleep mode, the power usage is so minimal, it's undetectable in my readouts. I have some monitors that have been in constant use for excess of 10 years. We tend to upgrade rather than replace, and then they get used elsewhere (kids, garage, security systems, etc). I believe we own about 1 dozen of various flat-screen types. We've had one quit in the last 14 or so years. It was probably dropped.

As far as hurting your monitor somehow by leaving it on...if it was left fully on, then yes technically you'd be imposing on the service life of the display (which is still pretty long, like 10-20 years), but if it's going into sleep mode automatically, then basically no worries.

(That all said, I do have a 10-year old iMac whose screen is failing, but that is due to faulty board, a known issue with 2011 iMacs, and not the display itself. Time for a new iMac as soon as the refresh is launched. )
