Example Calculation
Let’s say you have a 55-inch LED TV that consumes 100 watts on average, and you watch it for about 4 hours per day.
Energy Consumption = (100 W x 4 Hours) / 1000
Energy Consumption = 0.4 kWh per day
To find out the monthly consumption, simply multiply by the number of days in a month:
Monthly Energy Consumption = 0.4 kWh/day x 30 days
Monthly Energy Consumption = 12 kWh
Estimating the Cost of TV Energy Consumption
Now that you know how to calculate the energy consumption, it’s essential to understand how that translates into cost. The cost is derived from the energy provider’s rate per kilowatt-hour (kWh).
Estimation Formula
The formula for estimating the monthly cost of operating your TV is:
Cost per Month = Monthly Energy Consumption (kWh) x Rate per kWh
Example Cost Calculation
If your energy provider charges $0.12 per kWh and your TV consumes 12 kWh per month:
Cost per Month = 12 kWh x $0.12
Cost per Month = $1.44
This example illustrates how even though the consumption might seem small, it can add up over time, especially if you have multiple devices running.
Reducing Your TV’s Energy Consumption
Fortunately, there are several effective strategies to minimize your television’s energy usage without compromising your viewing experience.
1. Enable Eco Mode
