Monthly Usage (in kWh) = (Daily Usage x Days in a Month)
Assuming 30 days in a month:
- For a 200-watt smart TV used 4 hours a day:
Monthly Usage = (0.8 kWh x 30) = 24 kWh
- For a 100-watt smart TV used 4 hours a day:
Monthly Usage = (0.4 kWh x 30) = 12 kWh
Cost Analysis
To calculate the cost of running your smart TV each month, multiply the monthly kWh usage by your local electricity rate. For example, if the average cost of electricity is $0.12 per kWh:
- For the 200-watt TV:
Monthly Cost = 24 kWh x $0.12 = $2.88
- For the 100-watt TV:
Monthly Cost = 12 kWh x $0.12 = $1.44
This indicates that while the operating costs can be reasonable, larger and more feature-rich models may contribute significantly to your energy bill.
