If you don’t have the manual on hand, you can often find this information online by searching for your TV model along with “wattage” or “power consumption.”
Calculating Your TV’s Energy Cost
Once you know your TV’s wattage, you can easily estimate its energy usage over time and what it costs you. The formula to calculate energy consumption in kilowatt-hours (kWh) is straightforward:
Energy Consumption (kWh) = (Watts / 1000) * Hours of Use
Once you have the energy consumption rate, multiply it by your local electricity rates to find the overall cost.
Example Calculation
Let’s assume your 55-inch LED TV consumes approximately 120 watts and you watch it for 5 hours a day. Here’s how you would calculate your daily energy consumption and costs:
- Find daily energy consumption in kWh:
-
(120 Watts / 1000) * 5 hours = 0.6 kWh
-
Multiply by your electricity rate (let’s say $0.12 per kWh):
- 0.6 kWh * $0.12 = $0.072 per day
To find the monthly cost, multiply by 30:
– 0.072 * 30 = $2.16
Now you can make informed decisions about using your television in an energy-efficient way.
Tips for Reducing Your TV’s Wattage Consumption
While understanding your TV’s wattage is essential, implementing energy-saving practices can significantly reduce your electricity bills:
