Computers and other electronic equipment use electricity around the clock, even when not in use. Encourage employees to turn off all office equipment after hours and on weekends. Likewise, turn off lights.
By plugging office equipment into power strips, it makes it easier to turn them all off when not in use. Better yet, purchase a smart power strip, which senses when a product is not in use and eliminates its standby power consumption.
Screen savers save computer screens, not energy. Your monitor uses almost full power when the screen saver appears. Automatic switching to sleep mode or manually turning monitors off is always the better energy-saving strategy.
Use of plug-in timers to automatically turn printers, copiers, and simialr machines off is also an option
Heat loss resulting from loose or corroded electrical connections can also mean reduced operating efficiency. These conditions can also lead to arcing or a fire. An infrared survey of the electrical system should be performed at least every three years
For refrigerators, water coolers, and freezers maintain an air-gap of at least 3 inches between the back of the appliance and the wall. Also,clean condenser coils regularly.
