Adjust the room temperature when you are leaving a space for an extended period of time.
Use space heaters only when necessary and turn them off when not in the room.
Opening and closing a window to adjust the temperature affects more than just your space.
Unplug electrical office appliances when possible. Cell phone chargers, laptop chargers and other battery charging devices continue to use electricity even when not in use.
Shut your computer down. Standby and hibernate modes still use power when it is often unnecessary.
Turn off the lights when you are not in the room.
