How Much Energy Does Your Computer System Use?

• A typical desktop PC may require approximately
  100 watts of electrical power
• Add 50-150 watts for a 15-17 inch monitor,
  proportionately more for larger monitors
• Conventional laser printers can be as much as 100
  watts or more when printing though much less if
  idling in a sleep mode
• Ink jet printers use as little as 12 watts while
  printing and 5 watts while idling
