Questions about TV power

In the federal test, the middle ENERGY STAR 55–64″ TV draws about 119 watts, so 5 hours a day uses about 0.595 kWh. Across sizes, the range is 28–170 watts. A kilowatt-hour (kWh) is 1,000 watts for one hour.

At 119 watts for 5 hours a day, the middle ENERGY STAR 55–64″ TV uses about 18.1 kWh a month. Its cost is that kWh times your price per kWh. The calculator above multiplies it by your electric company’s average price, with all charges included, and shows the math.

The yellow EnergyGuide label shows the kWh a year your TV used in the federal test, at 5 hours a day. Multiply that by 1,000 and divide by 1,825 (5 hours × 365 days) for its watts, and type them into the watts field above.
