"A modern TV uses significantly less energy than one from a decade ago - which makes sense, given how much more power-efficient today's display panels have become. According to Perch Energy, the average power consumption of an old TV runs around $54 per year in energy costs. Because LED-backlit TVs and OLEDs consume less power than traditional LCD screens, newer models cost about $32 annually."
"In large part, the bigger your screen size, the more power your TV requires. But there are ways to attenuate your TV's power consumption every time you turn it on. Here are some settings you can change to save more money on your next electricity bill. Even if it's just tens of dollars that you're ultimately saving, it's still a little less money coming out of your pocket, and that's the goal."
"Ratings range from A to G, with an A rating being the highest and most energy-efficient. However, it is rare to find a TV with an A rating. For a smart TV, a rating of D or E is considered highly efficient. New TVs certified by ENERGY STAR must have comparable features and be 25% more energy-efficient than competitors. While many energy-efficient televisions may cost more upfront, you'll quickly recover the difference in price through energy savings."
Modern LED-backlit and OLED televisions consume noticeably less power than older LCD models, lowering annual energy costs from about $54 to roughly $32. Larger screen sizes generally increase power consumption, but users can reduce usage by adjusting TV settings. EnergyGuide labels and ENERGY STAR certification provide comparable metrics for efficiency, with ratings from A to G and D or E often considered efficient for smart TVs. ENERGY STAR-certified new TVs must be about 25% more energy-efficient than competitors. Energy-efficient models may cost more initially but typically recoup the difference through reduced electricity bills.
