Several years ago I was hunting down the source of interference to my audio recording equipment. I had replaced all the incandescent bulbs with CFs a few weeks before and with wet weather the problem became intolerable. I suspected the CF bulbs and borrowed a Fluke Power Quality meter to test them. The switching power supplies in them produce odd-order harmonics clear off the end of the scale and introduce a phase shift in the source power that reduces power factor to about 0.7. That power factor it totally unacceptable to utilities and if you're an industrial site they'll make you correct it by installing large, expensive capacitors. I mentioned this to a City Light muckei muck who said, "Oh really!" and went of as though he intended to do something about it. I never heard more.

I still use the CFs on hand but haven't bought more. You off-grid folks note that they will produce nearly as much electromagnetic interference as a square-wave inverter. Tube type units with ballasts are no problem.

And, of course, I got the word "permaculture" on the front page with me.

Please forward far and wide. I like the idea that my local newspaper sees
thousands of people looking at this article and thinks "hey, we should talk
about permaculture more often."
