The Annual Energy Consumption: What to Expect
To convert the technical figures into practical, understandable terms, it’s essential to consider how these numbers translate into annual energy usage. Suppose you have an LED TV rated at 100 watts, and you watch it for 5 hours a day.
Calculating Annual Power Consumption
To find the total energy consumption per year in kilowatt-hours (kWh), we can use the following formula:
Power (kW) x Hours Used x Days Used = Annual Consumption (kWh)
For our example:
Power in kW = 100 W / 1000 = 0.1 kW
Annual Consumption = 0.1 kW x 5 hours x 365 days = 182.5 kWh
Getting a Realistic Picture: Cost Implications
Now that we know the annual consumption, we can assess the financial impact. If the average cost of electricity is $0.13 per kWh, you can calculate your annual expenditure based on this usage:
Annual Cost = Annual Consumption (kWh) x Cost per kWh
So,
Annual Cost = 182.5 kWh x $0.13 = $23.68 per year
This is an approximate figure that helps illuminate the cost of running your TV.
