4. Usage Patterns
How long you leave your television on each day plays a significant role in overall energy consumption. A TV that’s on for several hours daily will naturally consume more electricity than one that’s used sparingly.
Calculating Your TV’s Electricity Cost
To accurately determine how much it costs to run your television, you first need to know its wattage. This information is usually found in the user manual or on the back of the unit.
The general formula for calculating electricity costs is as follows:
Cost = (Wattage x Hours Used x Cost Per kWh) / 1000
For example, let’s say you have a 50-inch LCD TV that consumes approximately 100 watts. If you watch TV for 4 hours a day and your electricity rate is $0.13 per kWh, the calculation would be:
Cost = (100W x 4 hours x $0.13) / 1000 = $0.052
This means you would be spending about 5.2 cents a day or $1.56 a month just for watching TV.
Common TV Wattages
To give you a better idea, here’s a general range of electricity consumption for different types of televisions:
| TV Type | Screen Size | Average Wattage |
|---|---|---|
| LCD | 32 inches | 50 – 70 watts |
| LCD | 50 inches | 80 – 120 watts |
| LCD | 65 inches | 120 – 180 watts |
| OLED | 55 inches | 100 – 150 watts |
| OLED | 65 inches | 150 – 200 watts |
These numbers are averages and can fluctuate based on individual settings and brands.
Understanding Your Electricity Bill
In understanding your TV’s electricity consumption, it is also essential to review how your utility company calculates your bill. Most electricity bills are based on the kilowatt-hour (kWh) unit of measurement.
What is a Kilowatt-Hour?
A kilowatt-hour is the amount of energy consumed when a 1,000-watt appliance runs for one hour. Thus, if you’re using your 100-watt television for 10 hours in a day, you are consuming 1 kWh (100 watts x 10 hours = 1,000 watts, or 1 kWh).
Understanding this unit helps clarify how much that seemingly innocent TV time can add up month after month.
