Operational Features
Smart TVs come with a multitude of features like built-in streaming applications, voice recognition, and enhanced graphic capabilities, often leading to increased power usage.
Viewing Time
How long you have the TV turned on daily also impacts the overall energy consumption. The longer you use the TV, the more electricity consumption accumulates, although this doesn’t affect the amps it draws at any single moment.
Understanding Energy Consumption Costs
Knowing how many amps your TV uses can also help you estimate your energy costs. Electricity costs can vary by region, but you can calculate your TV’s operational cost with this formula:
Calculating Electricity Costs
- Find the wattage of your TV (from the specifications).
- Multiply the wattage by the number of hours you watch TV each day.
- Multiply that result by your local electricity rate (usually given in kWh).
For example, if your TV uses 100 watts and you watch it for 5 hours a day:
Daily Consumption = (100W x 5 hours) / 1000 = 0.5 kWh
If your electricity cost is $0.12 per kWh:
Daily Cost = 0.5 kWh x $0.12 = $0.06
Over a month (30 days), this totals approximately $1.80.
