This depends heavily on hours of use. ENERGY STAR's annual figure is based on a fixed test assumption, not your actual viewing hours — a TV on 2 hours a day will cost much less than shown, one on 8 hours a day much more. Use it to compare models at the same size, not as your real bill.

15 ENERGY STAR certified models, from about $21 to $30 a year to run at the US average electricity rate. See how we calculate running costs.
