With 4 hours a day, electricity at $0.18/kWh and £0.26/kWh all-in.

A 55-inch LED TV uses about 80 W: four hours a day is about 115 kWh a year. Old plasma sets used three to four times as much.

Brightness matters a lot: “Vivid” or “Dynamic” modes can double consumption compared with “Standard” or “Cinema”. A recent TV uses under 0.5 W on standby.
