Changing lightbulbs will indeed do very little. It's back to pre-industrial living to have any real impact on CO2 levels in the atmosphere. You first Al baby!

One thing is for sure. These CFL bulbs take more energy to manufacture. They have electronics in them. And lots more materials. semiconductors,Capacitors, resistors,PC boards,coper,wires,magnet wire,ferrite core,lead solder,Mercury,Florescence coating. Did anyone ever consider all of that in relation to energy. They would never withstand EMP either. The old bulbs would be unfazed by EMP.
