Firstly, find the wattage of your LED TV. You can usually find this information in the user manual or on the manufacturer’s website.
2. Calculate Daily Consumption
Use the formula:
Daily Consumption (kWh) = (Wattage / 1000) x Hours Used
For instance, if your TV is 100 watts and you watch it for 5 hours per day:
Daily Consumption = (100 / 1000) x 5 = 0.5 kWh
3. Calculate Yearly Consumption
Multiply the daily consumption by the number of days in a year:
Yearly Consumption = Daily Consumption x 365
Continuing our example:
Yearly Consumption = 0.5 kWh x 365 = 182.5 kWh
4. Find the Cost
Finally, multiply the yearly consumption by your local utility rate (usually expressed in cents per kWh). If your rate is $0.13:
Yearly Cost = Yearly Consumption x Utility Rate
So, the total yearly cost would be:
Yearly Cost = 182.5 kWh x $0.13 = $23.73
By performing this simple calculation, you can get a rough idea of how much you spend on keeping your LED TV running each year.
Practical Tips for Reducing Energy Consumption
