To fully grasp the impact of standby power, it is essential to understand how much energy your TV and other devices actually consume while on standby. The energy consumption can vary significantly depending on the make and model of your television, with estimates ranging from 0.5 watts to 10 watts.
Calculating Your TV’s Standby Power Consumption
To calculate the standby power usage, you can use the formula:
Energy (in kWh) = Power (in watts) x Time (in hours) / 1000
For example, if you have a TV that consumes 3 watts on standby and it stays in this mode for 20 hours a day:
Energy = 3 watts x 20 hours / 1000 = 0.06 kWh per day.
Now, let’s see what this adds up to in a year:
0.06 kWh/day x 365 days = 21.9 kWh/year.
The Financial Impact
To translate this into financial terms, we need to consider the cost of electricity. Assuming the average electricity rate is $0.13 per kWh, the yearly cost would be:
21.9 kWh x $0.13 = $2.85 per year.
Though this might not seem like much initially, it can become significant when you multiply this by multiple devices or consider the long-term financial implications.
