As you may already know, February 17, 2009 marks the end of the analog TV signal, which means that if you haven’t already switched over to digital TV (if your cable doesn’t run through a box before it hits your TV), you’re going to need to pick up a digital-to-analog converter box to keep watching TV. Unfortunately, it’s expected that 22 million of these boxes are going to be purchased by Americans to keep their signal running, which amounts to more than 3 billion kilowatt hours, or roughly $270 million in additional electricity costs. So, if you are one of the people who is planning on picking up one of these boxes, make sure to check for the Energy Star rating on the package, or check out Energy Star’s website to get up-to-date advice on the best options available.Photo credit: DVice.com
