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) | |
|---|---|
| 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) | |
|---|---|
| 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.
