How much energy does a computer use if left on? I just want to know how much is being wasted. Give me an average

According to my electric company (JCPandL), a computer, on average, uses 600 Watts. This translates into $.07 per hour if the cost is $.11 kkWh (kilowatthour).

This was a great question.I have been wondering about this every time i get my electric bill but never called to ask them.So thank u.

Lots. My husband and I used to leave ours on all the time.
But, our electric bill was always huge. When my husband lost his job, we started cutting back. We shut the computer down when we weren%26#039;t using it. Our electric bill went down by $30.00 the next month. That was just with one computer and monitor. Next, we switched to those energy efficent light bulbs and it went down another $40.00 a month.

A computer actually uses surprising little energy to run. It is a modern day piece of equipment and with each new model they may have more and more bells and whistles as far as progams, but they are built to use less and less energy. You will note that in later models you have batteries that last longer and are more efficent, thus proving that all computer companies as not energy hogs.
The strange thing about a lot of computers is that if you use them daily, and use them a lot,it pays to leave them on, or in the resting position vs turning them on and off. You use more energy turning on and off a computer then you do just leaving it on all the time. i know I leave my notebook on all the time and just wake it up when I want to use it. I turn it off when I am leaving the house and traveling. A lot of modern electronics have been built this way, they just don%26#039;t draw the kind of energy used in older models. Companies know that it is better for the machines and the environment to make the machinery work this way. They also like to make things easier for the consumer. If one company does it they all have to do it, competition does help the consumer and the ecology.

It pays to leave them on, or in the resting position vs turning them on and off. You use more energy turning on and off a computer then you do just leaving it on all the time. It is also better for the equipment to keep it on so that it reduces the wear and tear of on and off.

When fully on, I would guess the computer consumes about 100W-300W. It has to do with the type of CPU, chipset, monitor, etc.

I cannot think of why it would take much more power to turn on a computer than to keep it on. I think that%26#039;s nonsense. It takes about a minute to turn on a computer. Even if it consumes 10 times the power during that time (which it doesn%26#039;t), you break even by having it off for just ten minutes.

Of course, it consumes less when it%26#039;s in various standby states (monitor off, hard drive off, standby, etc). I always use hibernate mode, which consumes 0W, and restarts exactly where you left off. Chip designer
