Calculating energy usage over a year:
- Incandescent:
- LED:
- 60 watts × 5 hours/day = 300 watt-hours/day
- 9 kWh/month (as calculated before) = 108 kWh/year
- Cost: 108 kWh × $0.12 = $12.96/year
- 10 watts × 5 hours/day = 50 watt-hours/day
- 1.5 kWh/month = 18 kWh/year
- Cost: 18 kWh × $0.12 = $2.16/year
The savings are evident. Switching to an LED allows for more than $10) saved each year for just one bulb. If you have a dozen bulbs in your home, you’re looking at over $120 saved annually.
