Want to chop $85 off your electricity bill in one easy step? Consider designating just one room in the house for watching television and not having multiple TVs set up all over the house. On average, a flat-screen TV uses about $7 a month in electricity -- not counting the cable box or other devices like gaming consoles and DVD players. But it's more than just economic savings: According to a study by the University of Michigan, 71 percent of teenagers have their own TV in their bedroom; kids 6 to 11 watch 28 hours of TV a week. The study showed excessive TV watching affected children's sleep, weight, grades and behavior. Instead of cutting the cord, have meaningful TV watching. And save a little money on the side, too.
