The standard monitor consumes more than the PC, so turn that off for a start.Next, the PC itself will probably consume around 130 watts, so if it's running for eight hours it will use about one kilowatt-hour of power, or about 10c worth. The monitor might consume about twice that amount is it was left on.It's no good putting the PC into sleep mode either, because it will stop receiving anything from the Internet.(The answer says that a typical PC consumes about 130 watts when it's just idling, such as downloading a file. Power is an instantaneous measure, and is measured in watts. The amount of electricity or "energy" used is measured in power x time or watt-hours. A unit of electricity is a kilowatt-hour which is the same as running a 100W light-bulb for 10 hours. Depending on where you live that costs around 10c. Even if your PC has a 400W power supply, that's only a measure of how much power the PC CAN consume at full load, not a measure of how much it does consume

Power consumption varies greatly depending on the computer. Certain CPUs and Video cards really suck up electricity. Newer computers often require more power than older computers. The reason people may think they use less is because they often come with LCD monitors. LCD monitors use much less electricity than the old CRT monitors. A good way to conserve electricity is just to turn off your PC if you won't be using it for a while. You can also set it to switch to low power mode when you are away from it.

Computers do take alot of energy to run. Especially of you have an older computer. Newer computers consume less energy but not by much. Our computer is left on all day our older computer would cost me about 60 dollars a month to keep on. I just got a brand new computer and now it cost about half that for my computer which is about a quarter of my electric bill. As far as how much wattage it uses I don't know the exact number.

a lot my parents electrical bill was about 140 to 160 without my computer. When i got my computer it jumped to a whopping 200 dollars. But i don't care i still love my computer. If you are trying to lower your bill invest in to solar panel. We did that this month and our bill is like 60 dollars. But the panels are kinda costly but they do pay out for them selfs in the long run.
