Turn off monitors when not in use

Monitors, especially old CRT monitors, can consume a lot of energy. Make sure that they are turned off when not in use.
Replace old CRT monitors with LCD monitors

LCD monitors are much more energy efficient that CRT monitors. You can run three LCD monitors for the price of one CRT.

Shut down unused equipment

If it is not being used, turn it off.
Move computer equipment into basement where it is cooler

Keeping your system cooler (without firing up an air conditioner) will allow it to work more efficiently and require less internal cooling. A more efficient system requires less power.

Turn off screen savers

If your monitor is turned off, why do you need a screen saver running? All these things do is use up system resources and increase energy usage. If you do need a screen saver, then make sure that the screen saver just shows a black screen.

Turn down the brightness on your monitor

The brighter your monitor, the more power it consumes.

Buy devices that consume less power

Consider the wattage required for a device when you are purchasing and select devices that use less power.
