Although today’s flat-panel televisions use far less energy than previous models, you can easily increase the savings even more. Go to your TV’s picture set-up menu and choose the “home” or “standard” screen setting – the “vivid” or “retail” settings are unnecessarily bright and burn up to 20 percent more power. Don’t forget to disable the “quick start” function that allows your TV to boot up a few seconds faster, but eats significantly more power during the 19 hours or so your TV is in standby mode but not being used. Or in order to save even more power, you can simply turn off your TV when not in use.
