Core Insights - The article highlights the often-overlooked electricity consumption of televisions, which can exceed that of larger appliances like air conditioners and refrigerators due to their increasing size and functionality [1][3]. Group 1: Electricity Consumption Details - Modern televisions, especially large-screen models (55 to 100 inches), can consume significant power, with a 75-inch 4K smart TV using 150-200 watts during normal operation, while a 1.5 HP energy-efficient air conditioner consumes around 1000 watts [1]. - Increasing the brightness of a TV by 10% can lead to an 8%-10% increase in electricity consumption, particularly when watching in low-light conditions [3]. - Televisions in standby mode still consume power, typically around 5-15 watts, with some complex models reaching up to 20 watts. This can accumulate to significant costs over a year [5][7]. Group 2: Long-Term Usage Patterns - Leaving the TV on for background noise can lead to higher electricity consumption than expected. For instance, a 75-inch TV running for 8 hours daily can consume approximately 432 kWh annually, costing around 260 yuan [11]. - The cumulative effect of these habits can result in substantial electricity bills, often surpassing that of other household appliances [11]. Group 3: Energy-Saving Tips - To reduce electricity consumption, it is recommended to completely power off the TV and unplug it after use, rather than just using the remote control [13][15]. - Adjusting brightness and volume settings according to the environment can lead to significant savings, with energy-efficient modes available on many smart TVs reducing consumption by 15%-20% [17][20]. - When purchasing a new TV, opting for energy-efficient models with lower power ratings can lead to long-term savings on electricity bills [18][20]. Group 4: Other Appliances - Besides televisions, other household appliances like set-top boxes, routers, washing machines, and microwaves also consume power in standby mode. It is advisable to unplug or switch off these devices when not in use to further reduce electricity costs [21][23].
