Wear comfortable business attire. Dress appropriately for cooler temperatures. Turn off any lights that are not needed, especially in unused offices and conference rooms. Turn down the remaining lighting levels if you can. Turn off your computer if you are out of the office for more than a few minutes.
Some computers have a low power stand by mode.
Check to see if your computer is set for it. If a Stage 3 is imminent, back up your computer and don't forget to frequently save what you are working on, to be ready if the power goes off. These actions can be taken quickly to reduce electricity consumption. With a little bit of planning, you can save even more energy and money. When It's Cold Outside Check your heating ducts to make sure that they are properly connected and not leaking air.
