Understanding Energy Consumption: Kilowatt-Hours
When you’re evaluating your TV’s power consumption, it’s essential to consider how electricity is billed. Power companies charge by the kilowatt-hour (kWh), which is a measure of energy consumed over time.
To calculate the monthly consumption:
- Find the average wattage of your TV.
- Multiply it by the number of hours you watch each day.
- Multiply that result by the number of days in a month.
- Finally, divide by 1,000 to convert watts to kilowatts.
For example, if you have a 100-watt TV that you watch for 5 hours a day:
100 watts * 5 hours = 500 watt-hours per day
Over a month (30 days):
500 watt-hours * 30 days = 15,000 watt-hours
And converting that to kilowatts:
15,000 watt-hours ÷ 1,000 = 15 kWh
If your electricity cost is $0.12 per kWh, your monthly TV usage would cost:
15 kWh * $0.12 = $1.80
