Most people with computers think you can save energy by simply enabling a screen saver. However, it does nothing but display an image of your choosing. You can place your computer in "sleep mode" which makes the hard drive and computer monitor use low power. When you are not using your computer equipment, turn your equipment completely off. Turn your monitor off when you leave for a meeting, class or go to eat. In addition, purchase Energy Star computer equipment when you are looking at buying new equipment.
Sometime people can inadvertently waste a lot of energy when copying and printing materials. Print and copy only materials that you need. Try to edit on the computer, rather than editing directly on paper. If you simply need a copy for review, save to a flash drive to review the material later. Send materials and documents via e-mail, rather than printing a copy for everyone on your distribution list. Organize your e-mails to save pertinent information, rather than printing every e-mail you receive.
When you are not using the lights in a room, keep the lights off. The College of New Jersey recommends a "10 Minute Rule" which states, "If you do not plan to be in your room or office for more than 10 minutes, turn off your lights." Rather than use electric lighting, use natural lighting when it is bright enough. In addition, place compact fluorescent bulbs or light emitting diode (LED) bulbs in desk lamps.
Keep heat in a room by closing the blinds and curtains when it is cloudy outside and at night. Open your drapes, blinds or curtains during the sunlight hours of cold seasons to let the sun heat the room. When it is hot outside and you need a cool room, keep your blinds and curtains closed to block the direct rays from the sun. In addition, set thermostats to 68 degrees and dress according to the weather. Also, use hot water only when it is necessary.
