Fallicy #1 - all CFL's are the same. Right now, they are a moving target as
the designs of their electronics packages becomes more sophisticated and
purpose-driven.
Dimmable CFL's are available in enough different wattages to be useful in a
wide variety of applications.
True that disposal is more critical especially because of the the mercury.
However, I've seen situations where CFL's outlast incadescents by 20:1.
They are both primarily made up of glass, which is recylcliable.
This is a very flawed argument. Industry is going to get the power they
need. They don't buy power for the fun of it.
Mixed bag.
In the summer, less heat means less need for air conditioning. In the
winter, less heat from electricity for lighting may have to be offset to
keep the rooms at the same temperature, but space heating often comes from
more efficient sources. Electricity generation has about 70% waste back at
the generating plant, plus significant losses due to transmission and
distribution. Natural gas doesn't have the 70% conversion cost, but it does
have some losses in transmission and distribution.
Only surely true in the winter. Even in the winter, space heating generally
comes by a more efficient path that was detailed above.
Clearly not true at all if you are cooling the room, which is true in maybe
90% of the US in the summer.

Quite apart from the problems of disposing of old CFLs, I
question the whole principle of Low Energy lighting.
In the summer, less heat means less need for air conditioning. In the
winter, less heat from electricity for lighting may have to be offset to
keep the rooms at the same temperature, but space heating often comes from
more efficient sources. Electricity generation has about 70% waste back at
the generating plant, plus significant losses due to transmission and
distribution. Natural gas doesn't have the 70% conversion cost, but it does
have some losses in transmission and distribution.
If
you have a conventional bulb, much of the energy output
is in the form of heat, which will help heat the room,
and consequently will reduce the need for other heating,
central or otherwise.
Only surely true in the winter. Even in the winter, space heating generally
comes by a more efficient path that was detailed above.
Putting in a low-energy lamp mean
that there is less heat being put into the room, and
consequently, more heat has to be supplied externally.
Clearly not true at all if you are cooling the room, which is true in maybe
90% of the US in the summer.
