The study shows that, on average, 75 inch TVs are slightly more efficient than 70 inch TVs.<\/p>\n\n\n\n 75 inch TVs use 203.36 kWh of electricity per year, on average.<\/strong> <\/p>\n\n\n\nThe most common 75 inch TV consumes 206 kWh, with the lowest consumption being 165.7 kWh.<\/p>\n\n\n\n These figures are for annual consumption, next let\u2019s briefly take a look at hourly consumption.<\/p>\n\n\n\n How much electricity does a TV use per hour?<\/h4>\n\n\n\nOn average, in On mode, TVs use 0.0586 kWh of electricity per hour.<\/strong><\/p>\n\n\n\n75 inch TVs use 0.1145 kWh of electricity per hour, on average, when On.<\/p>\n\n\n\n On average, when in On mode:<\/p>\n\n\n\n \n- 70 inch TVs use 0.1091 kWh of electricity per hour (p\/h).<\/li>\n\n\n\n
- 65 inch TVs use 0.0947 kWh of electricity p\/h.<\/li>\n\n\n\n
- 55 inch TVs consume 0.077 kWh of electricity p\/h.<\/li>\n\n\n\n
- 50 inch TVs use 0.0705 kWh p\/h.<\/li>\n\n\n\n
- 43 inch TVs consume 0.0478 kWh p\/h.<\/li>\n\n\n\n
- 40 inch TVs use 0.0341 kWh p\/h.<\/li>\n\n\n\n
- 32 inch TVs use 0.028 kWh p\/h.<\/li>\n\n\n\n
- 24 inch TVs use 0.0198 kWh p\/h.<\/li>\n\n\n\n
- 19 inch TVs use 0.0165 kWh of electricity per hour.<\/li>\n<\/ul>\n\n\n\n
To work out how much electricity your TV uses per hour, simply use the following formula:<\/p>\n\n\n\n Hourly electricity consumption (in kWh) = TV wattage x 1 (i.e 1 hour)<\/span> \/ 1,000<\/strong><\/p>\n\n\n\nFor example, the most common <\/strong>55 inch TV uses 82 watts when in On mode. Using the formula, this works out at 0.082. So, the most common 55 inch TV uses 0.082 kWh of electricity per hour.<\/p>\n\n\n\nBut what about when a TV is off?<\/p>\n\n\n\n How much electricity does a TV use when off?<\/h4>\n\n\n\nIf a TV is unplugged or disconnected from the power source, it will use no electricity.<\/p>\n\n\n\n However, all TVs, in the study of 107 of the most energy efficient TVs, use electricity on standby.<\/p>\n\n\n\n TVs use 0.5 to 3 watts of electricity when on standby.<\/strong><\/p>\n\n\n\nMost TVs in the study use 0.5 watts on standby, with the average being 1.3 watts.<\/p>\n\n\n\n Get details about the cost to run a TV in Standby mode, here<\/strong><\/a>.<\/p>\n\n\n\nTV power consumption calculator<\/h3>\n\n\n\nUse this TV power consumption calculator to estimate how much electricity your TV uses per hour, day, week, month and year, based on your own usage<\/strong>.<\/p>\n\n\n\nSimply enter your daily usage, for each mode, to see how much electricity your TV consumes.<\/p>\n\n\n\n And enter your TV\u2019s wattage (found on the back of your TV), or its actual power draw, if tested, which will be lower.\u00a0Then do the same for Standby mode.<\/p>\n\n\n\n Using your TV\u2019s wattage will show the maximum expected power consumption under normal operating conditions. While using your TV\u2019s actual consumption will result in a more accurate estimate, however, actual consumption figures are not readily available.<\/p>\n\n\n\n |
