Power Management Statistics

To know that you're reducing your power consumption, you need to know how much you're consuming. Several governmental agencies and energy companies offer energy calculators for you to properly calculate a reduction in your carbon footprint and electricity bills. If you think your computing habits consume more energy than an average user (see statistics below), pledge to practice a green technology tip.

Computer Energy Consumption (Average User)

Computer Type Energy Consumption
Desktop Computer 60-250 Watts
Computer with Active Screen Saver 60-250 Watts
Computer on Sleep or Standby 1-6 Watts
Laptop 15-45 Watts

Computer Monitor Energy Consumption (Average User)

Computer Monitor Type Energy Consumption
Typical 17" CRT 80 Watts
Typical 17" LCD 35 Watts
Sleeping Monitor 0-15 Watts
Monitor Turned Off 0-10 Watts

ENERGY STAR studies show that if every home office replaced just the computer equipment with ENERGY STAR labeled computer equipment, it would save 219 billion pounds of greenhouse gases. In addition, by using a smart power strip on your existing computer system, you can save more energy than by replacing your computer and you will be keeping more computers out of the landfills. The EPA found that a single compliant ENERGY STAR computer and monitor can save anywhere from $7 to $52 per year in electricity bills.
