With the light bulb ban going into effect Jan 1... here is some interesting math: A single 60w incandescent bulb uses ~45kWh more than its CFL/LED counterpart over the 1000 hour life of that bulb. So, if you can buy that bulb (and destroy it) for <$0.45 then you're paying ~$0.01 to "save" a kWh. I paid ~$15000 for a 10kWp array that will produce ~360000 kWh over 20 years or ~$0.04/kWh. So... it's a mathematical fact that buying the remaining incandescent inventory and destroying it is $/$ a more cost effective way of reducing CO2 than buying solar panels... Once they're gone they're gone. Law states they cannot be manufactured or imported. Bulb smashing party?
