BoB, I wasn't talking about coal power. I just wanted to remind some
people that there are tens of former coal mines in the world that have
been abandoned because of an uncontrolled fire. Most of them are in
Russia and in China. Those produce lots of CO2.

> "Very poor efficiency" is a meaningless subjecive term.  Yes the power supply in a CFL is only converting about 20% of the electricity to light, but that is 400% better than an incandescent wihch only produces 5% light at best!  Hence the 4-to-1 savings from using CFL's.
