Data
- Average kWh per home per year for lighting is 1700 kWh1
- EU Co2e emissions due to electricity generation is 0.296 kg Co2 per kWh2
- Average power consumption of 800-lumen (60-watt equivalent) LED bulb is 8.35 W3
LED efficiency factor
The LED efficiency factor is used to convert regular light bulb w consumption to LED watt consumption.
x = LED efficiency factor
60 W * x = 8.35 W | /60
x = 0.139
Average kWh per home per year for lighting with LED lighting
Average kWh per home per year for lighting * LED efficiency factor
1700 kWh * 0.139 = 236.3 kWh
kWH’s saved by switching to LED for a year
Average kWh per home per year for lighting – Average kWh per home per year for lighting with LED lighting
1700 kWh – 236.3 kWh = 1463.7 kWH
Co2 saved by switching to LED for a year
kWH’s saved by switching to LED for a year * EU Co2e emissions due to electricity generation
1463,7 * 0,296 = 433,2 kg Co2e
You can save approximately 433,2 kg Co2e a year in your household by switching to LED bulbs. You can save 433,2 kg Co2e a year by switching to LED bulbs.
