The resolution and refresh rate of your TV also impact its energy consumption. Higher resolutions, such as 4K or 8K, require more power to display the increased number of pixels. Similarly, higher refresh rates, such as 120Hz or 240Hz, also consume more energy.
Smart TV Features
Smart TVs with built-in Wi-Fi, streaming capabilities, and voice assistants consume more energy than non-smart TVs. This is because these features require additional processing power and memory, which increases energy consumption.
Calculating Your TV’s Energy Usage
To calculate your TV’s energy usage, you’ll need to know its power consumption in watts. You can find this information on the TV’s packaging, manual, or by searching online. Once you have the power consumption, you can use the following formula to calculate your TV’s energy usage:
Energy Usage (kWh) = Power Consumption (W) x Number of Hours Used
For example, if your TV consumes 100 watts of power and you use it for 4 hours a day, its daily energy usage would be:
Energy Usage (kWh) = 100 W x 4 hours = 0.4 kWh
To calculate your TV’s monthly energy usage, multiply its daily energy usage by 30:
Monthly Energy Usage (kWh) = 0.4 kWh x 30 = 12 kWh
How Much Does it Cost to Run a TV?
