Have you checked the Power management functions on your computer? Is yours set to “Always On” through days, nights and weekends?
In addition to the waste of energy, consider the following environmental effects:
| A. Computer and screen always on | 860 kwh per yr | 1804 lbs CO2/yr |
| B. Computer always on, screen on during work hours | 420 kwh per yr | 880 lbs CO2/yr |
| C. Computer and screen on during work hours | 200 kwh per yr | 418 lbs CO2/yr |
| D. As for C with screen sleep mode set to 15 minutes | 150 kwh per yr | 308 lbs CO2/yr |
| E. As for D with standby mode set to 1 hour | 130 kwh per yr | 275 lbs CO2/yr |
Office equipment accounts for approximately 7% to 10% of
office energy that is consumed. Minimizing our usage through power management
of our PCs and monitors will bring positive reductions to our energy profile.
