Energy consumption is probably not the first thing anyone considers when buying a new TV. Compared with obsolete CRTs, today’s LED-illuminated TV displays use very little energy, between 94 and 267 kilowatt-hours per year for a typical 55-inch display. (A CRT television of less than half that size used about twice as much energy.)
