How much energy, on average, does a flat-screen computer monitor use per hour?
I'm trying to calculate the savings to my employer if all of our employees simply powered down their monitors before leaving work at night. I'm unable to find the info on the company's website; the majority of the monitors are HP.
It depends on a variety of factors including screen size and the colors and brightness used (white uses far more energy than black) and on LCD's (flat-panel) a lot of motion uses more power, but about 50 watts per monitor is typical during normal use (with about 2 watts when in standby).
So, multiply 50 times number of hours of use times number of monitors, divide by 1000, and that's how many kilowatt-hours you're using on the montiors.

It varies by monitor I would check how many Vaults your monitor uses then calculate it.
Multiply the Vaults by the cost which can be from your energy supplier.
