Energy eaters: Watching your fridge may be boring but it can save you money.

When it comes to energy, super-size television screens are even hungrier than refrigerators.

Here’s a breakdown of the annual electricity cost, based on the Department of Energy’s 2007 national average price for energy of 10.65 cents per kilowatt-hour. The researchers assumed eight hours of TV watching per day.
