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].

Group 1 - The article discusses the debate between sleeping with air conditioning versus open windows during hot summer nights, suggesting that air conditioning is generally more beneficial for health, especially for vulnerable populations like the elderly [1][3] - Recommended temperature settings for air conditioning are 22℃ to 26℃ for comfort, while at night, it is suggested to set the temperature to 28℃ for optimal comfort and energy savings [5][6] - The article highlights the importance of using air conditioning properly to avoid "air conditioning disease," which is often caused by improper usage rather than the air conditioning itself [3][6] Group 2 - It is advised to use the sleep mode on air conditioning units, which gradually increases the temperature during the night to prevent chills and save energy [7] - The article recommends positioning the air conditioning vents to blow air upwards to achieve a more even and comfortable room temperature [9] - Utilizing the dehumidification mode during humid weather can help reduce indoor humidity and save energy [10] - To combat dryness caused by prolonged air conditioning use, placing a bowl of water near the air vent can alleviate symptoms like dry eyes [11] - Regularly opening windows for ventilation is encouraged to maintain fresh indoor air and reduce harmful substances [12]
