CFLs and LED bulbs
CFL and LED bulbs use about 4 the energy of incandescents
• CFL lasts 7500 hours, Incandescent lasts 750 hours
• Regular incandescents already banned in EU, and 2012 in USA save 23-1GW
• If all incandescents replaced with CFLs in USA
nuclear power plants

CFL Economics:

•
Assume: CFL = $3.00 using 18 W Incandescent = $0.40 using 75 W
Assume: 4 hours per day at $0.10/kWh
3.004 Days = 114
If CFL life = 7500 hours, then = 10 incandescents. Saving $43.75
0.018* D* 0.10 0.40+ 4* 0.075* D* 0.10
• CFL and mercury:
Illegal to put in garbage
―
- Dispose of properly - Home Depot, OSH, Ikea
- Burning coal for inefficient incandescents releases more mercury
