Energy vampires are devices that feed on electricity all the time — even when they’re not in use. Some of the most common items in your home are the biggest culprits, including TVs and DVRs, and chargers for cell phones, laptops, MP3 players and handheld gaming devices.

In fact, all of these devices together can account for up to 20 percent of your monthly energy costs. But you can fight back with smart energy use. Check out these videos starring Sir Purr, the Carolina Panthers’ mascot, as he learns about energy vampires and then fights them in an effort to reduce his energy use and save money.
