The 30 to 70 watts range gives you a good idea of the average performance, but several factors could change these figures:
- Brand and Model: Some brands emphasize energy efficiency, while others may not focus on it as much.
- Usage Patterns: Just like a refrigerator’s use varies throughout the day, the way you use your TV affects its power consumption.
For instance, using the TV for extended periods, particularly at higher brightness settings, will cause the wattage to lean more towards the higher end of that range.
Breaking It Down: Daily and Monthly Consumption
To put this into perspective, let’s break down the daily and monthly electricity consumption of a 32-inch TV:
- Daily Consumption:
To estimate daily electricity costs, we can use the formula:
Consumption (kWh) = (Watts × Hours Used) / 1000
If you watch TV for an average of 5 hours a day, and we take a midpoint of the wattage, say 50 watts:
-
Daily Consumption:
(50 W × 5 hours) / 1000 = 0.25 kWh per day -
Monthly Consumption:
Taking this daily figure and multiplying it over a month (30 days):
- Monthly Consumption:
0.25 kWh × 30 days = 7.5 kWh per month
Now let’s consider the cost of electricity, which varies by region, but a common average is about $0.13 per kWh in the U.S.
- Monthly Cost:
7.5 kWh × $0.13 = approximately $0.975
Therefore, watching a 32-inch TV for 5 hours every day could cost you around $1.00 a month in electricity.
