The computers in your school are wasting energy. You can help your school save money. Implement computer monitor power management.
What Y’All Need to Remember:
- Screen savers DO NOT save energy!
- A typical monitor uses 60-90 watts
- While in sleep mode a monitor uses 2-10 watts
- Your Energy Star features may not be enabled
- Use free Energy Star software to capture savings
- Utilize your network, put all monitors to sleep at once
- Turn off your monitor at night
- Save energy, save money, prevent pollution
Some actual examples from districts that already set their monitors to sleep:

If all of the estimated 1.2 million computer monitors in Texas schools were enabled for monitor power management, Texas would save up to $20.5 million each year:
