In California, at least, consumers are converting from incandescents and
CFLs to LEDs so quickly that planned new power plants will be unnecessary.
This is a Good Thing. Home Depot has massive displays of LED bulbs, which
are now down to around $3 per (in the FunSize 3-pack). IKEA is even cheaper.
I think everything in our house is now LED except for some candelabra-size
25-W bulbs in the dining room. My wife doesn't like the look of the LED
replacements in this category, but eventually they, too will go. Then our
electricity consumption due to lighting will be down by 84% for the entire
house.
Edison would have been amazed to put his hand on a cool 10-W LED bulb
that's putting our just as much light as a hot 60-W incandescent. Or maybe
he would have been jealous.

I was just thinking that I had removed all of the CFL bulbs from my
house, because I hate them, their horrid colour, their slow start up and
that they do not last and smoke. Then tonight my wife called me to say that
the hall light had stopped working, the last CFL in the house. No smoke,
just dead. It has hardly been used in the years we have had it.
I have replaced all my CFLs with Halogen clear bulbs (40 watts) which we
can still get through some loophole, at least for now. I care not that they
produce some heat as well as light, as it warms the house up who we have
the lights on in the winter. I am stockpiling them.
I have LEDs in the bathroom that don't appear to cause any noise,
ironically the 12 V halogen ones before did because of the SMPSU that they
used.
I also have a Phillips LED lamp bulb in a table lamp that is totally RF
quiet.

That sounds like the CFL failed as it was designed to fail.
CFLs draw more current as they age. Eventually the power supply is
overwhelmed by the current demand and fails. All the CFLs I've seen use
a
tiny (1/8 or 1/16 watt) resistor as a fuse. Before anything else gets
overloaded enough to fail, the little resistor acts as a fuse and opens.
But, being a resistor, it fails like a resistor often with some smell
and
brief puff of smoke. I suppose it might be possible for a flame as the
covering burns, but that should be inside the base enclosure. I've never
seen anything but a small puff of smoke if I am looking in that
direction
when it goes.
