Computers run off of DC power. There is an internal converter on desktops, and the large block on a laptop cord is the converter for them. On laptops, a battery runs things, batteries are DC power.

The best thing you can do to save energy is to get one of the modern flat monitors - those use much less energy than the old-fashioned big (CRT) screens. The electrical specifications on the power supply (often limited to something like 500W) merely refer to the MAXIMUM power that the power supply may deliver; if that power is passed, the power supply might get damaged. However, depending on what is inside the computer (how many hard disks, what kind of CPU, etc.), the computer may actually use quite a bit less.
My computer consumes about 75 watts with normal use. If I am using the CD or DVD it will be higher. Fast graphics or other intensive uses could push it higher. It has a Phenon triple core processor and a 450 watt 80% efficiency power supply. Using a cheaper power supply, usage was about 83 watts.
I am using a 16" asus lcd monitor which consumes 14 watts. I think my 22" at home uses about double that.

A desktop computers power/energy consumption varies from system to system. Every monitor and PSU (power unit) model has its own rated power usage. If you look up your monitors (screens) power usage online and then add that to your PSU (Big power box inside of case that powers all the insides) You will have you power usage. That is only an estimate as the efficiency and amount of power required (less power used when your not doing anything, more when your doing something such as gaming/internet) also effect the outcome.
For a gaming, enthusiast, graphic design, high end system a 750W-1200W PSU are most commonly used.
For a basic home used computer the power usage varies from approximately 300W-750W

Organisms use energy computer uses energy, so the answer is pretty much everything.
What sort of energy does a computer use?
Solar energy
Does a virus use energy?
maybe cause the computer uses energy
What kind of energy does a computer produce?
Computers do not produce energy, they use/consume energy.
How much energy is used making a computer?
me
What energy trans formations are in a computer?
Electronic circuits, such as the one used in a computer, use electric energy. As it is used up, such energy is converted into heat energy.
What source of energy does a computer use?
A computers energy source is electricity. When using a computer plugged in or not it is drawing electricity from the battery or from a plug which is connected into the PC and a wall outlet. When there is no electricity the computer cannot function.
What type of energy does computers use?
The type of energy a computer uses is electricty.
What energy is produced when a computer is use?
heat and light
Is a washer wii and a computer a use of energy?
Yes, all use a certain type of energy known as electricity.
How much energy does Google use?
They use way to much energy, but what would we do with out google. :)
Does turning down the brightness on your computer save energy?
of course it does, you don't use the energy to keep it running, hence, you save energy.
