Refrigerators

Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper or a peso bill so it is half in and half out of the refrigerator. If you can pull the paper or bill out easily, the latch may need adjustment, the seal may need replacing, or you may consider buying a new unit. Regularly defrost manual-defrost freezers and refrigerators Frost buildup decreases the energy efficiency of the unit. Don’t allow frost to build up more than one quarter of an inch.
Smart Power Strips

Television
Switch off your TV when you’re not watching. Switching to standby is better than leaving your TV on, but it’s still more energy-efficient to switch it off completely. Make sure the brightness of your TV is right for your room. Factory settings are typically brighter than necessary.
