- The average household uses 8900kW of electricity per year.
- 8.8% is used for lighting = 783 kW
- Average household uses 8 Tons of CO2 = 0.7 tons impact from lighting
- Average household has 45 60W light bulbs
- Energy saver light bulbs are 454% more efficient than incandescent light bulbs. 60w = 13w energy saver.
