You can use the formula below to calculate energy costs:
Energy Cost = (Watts × Hours Used Per Day ÷ 1000) × Kilowatt-Hour Rate × Days Per Month
Assuming the rate is $0.12 per kWh:
If your TV consumes 100 watts:
Daily: (100 \, W × 4 \, hours \div 1000 = 0.4 \, kWh)
- Monthly (30 days): (0.4 \, kWh × 30 = 12 \, kWh)
- Annual: (12 \, kWh × 12 = 144 \, kWh)
Finally, multiply by the electricity rate:
– Annual Cost: (144 \, kWh × 0.12 = $17.28)
This means you would spend approximately $17.28 per year on electricity for this particular TV.
